Actron Automobile Parts 9620 User Manual

SFI or SEFI:  
Sequential Fuel Injection or Sequential Electronic Fuel Injection. A fuel injection system  
that uses one or more injectors for each cylinder. The injectors are mounted in the  
intake manifold and are fired individually.  
ST:  
Short Term fuel trim.  
TBI:  
Throttle Body Injection. A fuel injection system having one or more injectors mounted in a  
centrally located throttle body, as opposed to positioning the injectors close to an intake  
valve port. TBI is also called Central Fuel Injection (CFI) in some vehicles.  
TDC:  
Top Dead Center. When a piston is at its uppermost position in the cylinder.  
Throttle Body:  
A device which performs the same function as a carburetor in a fuel injection system. On a  
throttle body injection (TBI) system, the throttle body is both the air door and the location of  
the fuel injectors. On port fuel injection systems (PFI, MPFI, SFI, etc.), the throttle body is  
simply an air door. Fuel is not added until the injectors at each intake port are activated. In  
each case, the throttle body is attached to the accelerator pedal.  
TPS:  
Throttle Position Sensor. Potentiometer-type sensor connected to the throttle shaft. Its voltage  
signal output increases as the throttle is opened. The PCM uses this signal to control many  
systems such as idle speed, spark advance, fuel delivery, etc.  
TTS:  
Transmission Temperature Sensor. A resistance sensor mounted in the transmission  
housing in contact with the transmission fluid. It sends a voltage signal to the PCM indicating  
the temperature of the transmission.  
VECI:  
Vehicle Emission Control Information. Adecal located in the engine compartment containing  
information about the emission control systems found on the vehicle. The VECI is the  
authoritative source for determining whether a vehicle is OBD II-compliant.  
VIN:  
Vehicle Identification Number. This is the factory-assigned vehicle serial number. This  
number is stamped on a number of locations throughout the vehicle, but the most prominent  
location is on top of the dashboard on the driver’s side, visible from outside the car. The VIN  
includes information about the car, including where it was built, body and engine codes,  
options, and a sequential build number.  
VSS:  
Vehicle Speed Sensor. Sends a frequency signal to the PCM. The frequency increases as  
the vehicle moves faster to give the PCM vehicle speed information used to determine shift  
points, engine load, and cruise control functions.  
WOT:  
Wide-Open Throttle. The vehicle operating condition brought about when the throttle is  
completely (or nearly) open. The PCM will typically deliver extra fuel to the engine and de-  
energize the A/C compressor at this time for acceleration purposes. The PCM uses a  
switch or the Throttle Position Sensor to identify the WOT condition.

Closed Loop (CL):  
Safety Precautions  
A feedback system that uses the O2 Sensor(s) to monitor the results of combustion.  
Based on the signal(s) from the O2 sensor(s), the PCM modifies the air/fuel mixture to  
maintain optimum performance with lowest emissions. In closed loop mode, the PCM  
can “fine tune” control of a system to achieve an exact result.  
General Safety Guidelines to Follow When Working on Vehicles  
To prevent accidents that could result in serious injury and/or damage  
to vehicle or test equipment, carefully follow these safety rules and  
test procedures at all times when working on vehicles:  
CO:  
Carbon Monoxide  
Continuous Memory Codes:  
See Pending Codes.  
• Always wear approved eye protection.  
• Always operate the vehicle in a well-ventilated area. Do not inhale exhaust  
gases — they are very poisonous!  
CPS:  
Crankshaft Position Sensor. Sends a frequency signal to the PCM. It is used to reference  
fuel injector operation and synchronize spark plug firing on distributorless ignition  
systems (DIS).  
• Always keep yourself, tools and test equipment away from all moving or hot  
engine parts.  
CTS:  
• Always make sure the vehicle is in Park (Automatic transmission) or neutral  
(manual transmission) and that the parking brake is firmly set. Block the  
drive wheels.  
Coolant Temperature Sensor. A resistance sensor that sends a voltage signal to the  
PCM indicating the temperature of the coolant. This signal tells the PCM whether the  
engine is “cold” or “warm”.  
• Never lay tools on vehicle battery. You may short the terminals together  
causing harm to yourself, the tools or the battery.  
Data Link Connector (DLC):  
Connector providing access and/or control of the vehicle information, operating  
conditions, and diagnostic information. Vehicles with OBD II use a 16-pin connector  
located in the passenger compartment.  
• Never use scan tool if its internal circuitry has been exposed to any liquids.  
• Never smoke or have open flames near vehicle. Vapors from gasoline and/or  
charging battery are highly flammable and explosive.  
Data Stream:  
The actual data communications sent from the vehicle’s PCM to the data connector.  
• Never leave vehicle unattended while running tests.  
DEPS:  
• Always keep a fire extinguisher suitable for gasoline/electrical/chemical fires  
handy.  
Digital Engine Position Sensor.  
Detonation:  
See Knock.  
• Always use extreme caution when working around the ignition coil, distributor  
cap, ignition wires, and spark plugs. These components contain high voltage  
when the engine is running.  
DTC:  
Diagnostic Trouble Code. An alphanumeric identifier for a fault condition identified by  
the On Board Diagnostic System.  
• When performing a road test, never operate the scan tool alone while driving  
the vehicle. Always have one person drive the vehicle while an assistant  
operates the tester.  
DI/DIS:  
Direct Ignition/Distributorless Ignition System. A system that produces the ignition spark  
without the use of a distributor.  
• Always turn ignition key OFF when connecting or disconnecting electrical  
components, unless otherwise instructed.  
Duty Cycle:  
A term applied to signals that switch between “on” and “off”. Duty cycle is the percentage of  
time the signal is “on”. For example, if the signal is “on” only one fourth of the time, then the  
duty cycle is 25%. The PCM uses duty cycle type signals to maintain precise control of an  
actuator.  
• Always follow vehicle manufacturer’s warnings, cautions and service proce-  
dures.  
ECT:  
WARNING!  
Engine Coolant Temperature sensor. See CTS.  
Some vehicles are equipped with safety air bags. You must follow  
vehicle service manual cautions when working around the air bag  
componentsorwiring.Ifthecautionsarenotfollowed,theairbagmay  
open up unexpectedly, resulting in personal injury. Note that the air  
bag can still open up several minutes after the ignition key is off (or  
even if the vehicle battery is disconnected) because of a special  
energy reserve module.  
EFI:  
Electronic Fuel Injection. Any system where a computer controls fuel delivery to the engine  
by using fuel injectors.  
EGR:  
Exhaust Gas Recirculation. The PCM uses the EGR system to recirculate exhaust gases  
back into the intake manifold to reduce emissions. EGR Recirculation is used only during  
warm engine cruise conditions. EGR flow at other times can cause stalling or no starts.  
EPA:  
Environmental ProtectionAgency.

Appendix B:Glossary & Definitions  
Section 1: Vehicle Computer Systems  
A/C:  
1.1 Introduction  
Air Conditioning.  
This section describes the engine computer control system, types of sensors and how  
the computer controls engine fuel delivery, idle speed and timing. Additional information  
may be found in the technical support books at your local library or auto parts store. The  
more known about the computer system, the easier the problem can be diagnosed.  
A/F:  
Air/Fuel ratio. The proportion of air and fuel delivered to the cylinder for combustion. For  
example, an A/F ratio of 14:1 denotes 14 times as much air as fuel in the mixture. A  
typical ideal A/F ratio is 14.7:1.  
Computer controls were originally installed on vehicles to meet federal government  
regulations for lower emission levels and improved fuel economy. This began in the early  
1980’s when basic mechanical systems were no longer able to accurately control key  
engine parameters. A computer could be programmed to control the engine under various  
operating conditions, making the engine more reliable. While these early systems were  
very limited in scope of their diagnostics, providing only 10-14 trouble codes, they did help  
guide the vehicle repair process.  
AC Clutch Relay:  
The PCM uses this relay to energize the A/C clutch, turning the A/C system on or off.  
AC Pressure Sensor:  
Measures air conditioning refrigerant pressure and sends a voltage signal to the  
PCM.  
AC Pressure Switch:  
In 1994, manufacturers began equipping vehicles with a new class of computer technology  
which puts more processing power under dash than ever before. It is called On-Board  
Diagnostics version II, or OBD II. It is required on all vehicles sold in the US beginning  
January 1, 1996 (though most domestic manufacturers introduced it earlier than required),  
and offers increased system monitoring and diagnostic information. This new system stores  
a library of more than 650 general trouble codes and another approximately 400  
manufacturer-specific codes, all of which can be accessed with the scan tool. These codes  
cover Body Systems (B-Codes), Chassis Systems (C-Codes), Communications Codes  
(U-Codes), and Powertrain Systems (P-Codes). Now, basic terms are standardized and  
all generic codes will share a common format and terminology that manufacturers and the  
Society of Automotive Engineers (SAE) designed.  
A mechanical switch connected to the A/C refrigerant line. The switch is activated  
(sending a signal to the PCM) when the A/C refrigerant pressure becomes too low.  
Actuator:  
Actuators such as relays, solenoids, and motors allow the PCM to control the operation  
of vehicle systems.  
Air Injection Reaction (AIR) System:  
An emission control system operated by the PCM. During cold starts, an air pump  
injects outside air into the exhaust manifold to help burn hot exhaust gases. This  
reduces pollution and speeds warm-up of oxygen sensors and catalytic converters.  
After the engine is warm, the air will either be “dumped” back to the atmosphere (or into  
the air cleaner assembly) or sent to the catalytic converter.  
The OBD II Professional Scan Tool performs OBD II functions on ALL makes of OBD II  
compliant vehicles from 1994 and up.  
Bank 1:  
1.1.1 What The Computer Controls  
The main control areas of the vehicle computer are fuel delivery, idle speed, spark advance,  
and emissions controls. Some on-board computers may also control the transmission,  
brakes, and suspension systems as well.  
The standard way of referring to the bank of cylinders containing cylinder #1. In-line  
engines have only one bank of cylinders. Most commonly used to identify the location of  
oxygen sensors. See O2S, Sensor 1, Sensor 2.  
Bank 2:  
The standard way of referring to the bank of cylinders opposite cylinder #1. Found on V-  
6, V-8, V-10, etc. and horizontally opposed engines. Most commonly used to identify the  
location of oxygen sensors. See O2S, Sensor 1,Sensor 2.  
1.1.2 What Has Not Changed  
Acomputer-controlled engine is very similar to the older, non-computerized engine. It is still  
an internal combustion engine with pistons, spark plugs, valves, and camshaft(s). The ignition,  
charging, starting, and exhaust systems are very similar as well. Test and repair of these  
systems are the same as before. The technical manuals for these components provide  
instruction on how to perform the tests. Additionally, compression gauges, vacuum pumps,  
engine analyzers, and timing lights will continue to be used.  
BARO:  
Barometric Pressure Sensor. See MAP Sensor.  
Boost Control Solenoid:  
A solenoid that is energized by the PCM, in order to control supercharger boost pressure.  
Brake Switch Signal:  
1.1.3 Computer Control System  
An input signal to the PCM indicating that the brake pedal is being pressed. This signal  
is typically used to disengage Cruise Control systems and Torque Converter Clutch  
(TCC) solenoids. See also TCC.  
The vehicle on-board computer, or Powertrain Control Module (PCM), is the “heart” of the  
system. It is sealed in a metal box and connected to the rest of the engine by a wiring  
harness. The PCM is commonly located in the passenger compartment, behind the  
dashboard (kick panel position), although some manufacturers locate the PCM in the  
engine compartment. The PCM is programmed by the factory. The program is a complex  
list of lookup tables and instructions telling the computer how to control the engine based  
on various driving conditions. It does this using sensors to monitor what is happening and  
then provide feedback through a network of switches and actuators throughout the vehicle.  
CAM:  
Camshaft Position Sensor. Sends a frequency signal to the PCM in order to synchronize  
fuel injector and spark plug firing.  
CARB:  
California Air Resources Board. Governing body for emissions control in California.  
CKP REF:  
Crankshaft Position Reference.

REL TPS (0 - 100%)  
Relative Throttle Position is relative throttle position at normal position.  
1.2 Data Link Connector and Location  
The tester communicates with the vehicle PCM via a data  
link connector (DLC) – also referred to as a J1962  
connector. The term J1962 is taken from physical and  
electrical specification number assigned by SAE (Society of  
Automotive Engineers).Astandardized DLC means all compliant  
vehicles will use the same DLC with the generic link information available on the same  
pins regardless of vehicle make or model. In addition to the connector definitions, is a  
guideline on where the connector is to be located in the vehicle. This guideline states  
that the DLC should be located under the dashboard on the driver side of the vehicle.  
However, not all OBD II DLCs are located under the dash on the driver side. If required,  
refer to vehicle service documentation for the DLC location.  
SECONDAIR (AIR_STAT: UPS, DNS or OFF)  
Commanded Secondary Air Status is on newer vehicles and actuators to control pollu-  
tion control.  
UPS - UP STREAM module is demanding that secondary air be added at exhaust  
manifolds  
DNS- DOWN STREAM module is demanding secondary air be added at catalytic  
converter  
OFF - Module is demanding no secondary air to be added.  
ST FTRMxy (-100 - 99.22%)  
Short-term Fuel Trim Bank calculated value represents the short-term relation of fuel  
metering on a fuel-injected engine.  
NOTE: Short-term Fuel Trim calculated value that has a positive percentage is a rich fuel  
trim and if a negative percentage is present the fuel trim is lean.  
ST FLTRMx (-100 - 99.2%)  
Short-term Fuel Trim value represents the short-term relation of fuel metering on a fuel-  
injected engine.  
NOTE: Short-termFuelTrim valuewithapositivepercentageisarichfueltrimandifanegative  
percentage is present the fuel trim is lean.  
THR POS (0 - 100%)  
Absolute Throttle Position is the position the throttle is located. The more the throttle is  
closed the less percent shown.  
THROT CMD (0 - 100%)  
DLC Location  
Commanded Throttle Actuator Control is the position of the throttle. If throttle is closed the  
percent will be 0 and if wide open 100%.  
1.3 OBD II Scan Tool Hookup  
The OBD II cable attached to the scan tool fits the OBD II DLC. Because the OBD II J1962  
connector contains dedicated pins for power and ground, only a single cable connection is  
required for both scan tool power and PCM communication.  
TRIPS SNC CLR (0 - 255)

2.3.1 I/M Readiness  
Purpose of the I/M Readiness test is to display current information on emissions-related  
systems. These systems are required by OBD II regulation to be monitored for emissions  
testing. OBD II I/M Readiness Monitors are strategies designed to test operations of emission  
related systems or components. The computer module uses these monitors to check for  
correct operations of system and components as well as out of range values. The computer  
module may perform a special test on a system or component to complete the monitor. It  
may be required to operate vehicle under certain conditions in order to perform an accurate  
test. If computer module loses power, or codes are erased, monitors may be cleared.  
The scan tool displays the state of vehicle OBD II Monitors.

2.3.6 View Freeze Data  
Section 3: Diagnostic Trouble Codes (DTC)  
When an emission-related fault occurs, certain vehicle conditions are recorded by the  
on-board computer. This information is referred to as a Freeze Frame data. The information  
is a “snapshot” of operating conditions at time of a fault. This data can be overwritten by  
faults with a higher priority.  
3.1 DTC Format  
Diagnostic Trouble Codes (DTCs) consist of a five-digit alphanumeric code. The DTC  
format and types are shown below. When the on-board computer recognizes and identifies  
a problem, a DTC for that fault is stored in memory. These codes are intended to help you  
determine the root cause of a problem.  
NOTE: If codes were erased, then freeze frame data may not be stored in vehicle memory.

OBD II regulations require that applicable vehicles monitor and test the oxygen (O2)  
sensors to determine problems related to fuel and emissions. The O2 Monitor Test  
allows retrieval of completed O2 sensors monitor test results.  
O2 sensors are located before (upstream) and after (downstream) catalyst(s). The  
sensors are named (xy) for their position relative to both cylinder banks and catalysts.  
J2012 and ISO 15031-6 are standards for all DTCs, established by SAE, International  
Organization for Standardization (ISO) and other governing bodies. Codes and definitions  
assigned by this specification are known as Generic OBD II codes. OBD II requires  
compliance with standards, and has made it standard for all cars, light trucks, APVs,  
MPVs, and SUVs sold in U.S. Codes not reserved by SAE are reserved for manufacturer  
and referred to as Manufacturer Specific.  
• The O2 sensor for cylinder bank 1 has the prefix 1y while the O2 sensor for  
cylinder bank 2 has the prefix 2y.  
• The O2 sensor upstream of the catalyst (closest to the engine) has the suffix x1  
while the O2 sensor downstream of the catalyst has suffix x2. If vehicle contains  
more catalysts, the O2 sensor downstream of the second catalyst has the suffix  
x3 and the O2 sensor downstream of the next catalyst has the suffix x4.  
Periodically, new DTCs are defined and approved by SAE, ISO and other governing  
bodies. The scan tool software will be periodically updated to reflect these changes. For  
more information regarding DTC updates, please call our Technical Support line at  
1-800-228-7667 (8:00 – 6:00 EST Monday – Friday), or send an email to  
• For example, O2S 21 is the upstream O2 sensor for cylinder bank 2.  
The following O2 sensor tests are available:  
• Rich to Lean sensor threshold voltage  
• Lean to Rich sensor threshold voltage  
• Low sensor voltage for switch time  
• High sensor voltage for switch time
