communication protocols from year-to-year.

The tables below highlight changes for GM, Ford, and Chrysler. If this seems confusing; don’t worry. Your tool makes it easy. Based on the VIN information selected during Scan Tool setup, the processor is automatically recognized. All you have to do is choose the correct adapter cable and jumper wires (if necessary). Details on adapter cables and jumper wires may be found in “Diagnostic Link Connectors (DLC)” on page 2-4

OBD II stands for On-Board Diagnostics version II. OBD II is a system that the Society of Automotive Engineers (SAE) developed to standardize automotive electronic diagnosis. Technicians now can use the same tool to test any OBD II compliant vehicles without special adapters. The SAE established guidelines that provide:

• a universal diagnostic test connector, called the data link connector (DLC), with dedicated pin assignments.

• a standardized location for the DLC, visible under the dash on the driver’s side.

• a standardized list of diagnostic trouble codes (DTCs) used by all manufacturers.

• a standardized list of parameter identification (PID) data used by all manufacturers.

• the ability of the vehicle system to record a freeze frame of the operating conditions when a fault occurs.

• expanded diagnostic capabilities that records a code whenever a condition occurs that effects vehicle emissions.

• the ability to clear stored codes from vehicle memory with the scan tool.

In addition, SAE has published hundreds of pages of text defining a standard communications protocol that establishes the hardware, software, and circuit parameters of OBD II systems. Unfortunately, vehicle manufacturers have different interpretations of this standard communications protocol. As a result, the generic OBD II communications scheme used will vary, depending on the vehicle.

Getting Started

SAE publishes recommendations, not laws, but the Environmental Protection Agency (EPA) and California Air Resources Board (CARB) made many of SAE’s recommendations legal requirements that vehicle manufacturers were required to phase in over a three-year period. Beginning in 1994, vehicles with a new engine management computer – about 10% of each manufacturers fleet – were supposed to comply with OBD II standards. For 1995, OBD II systems were to appear on about 40% of the new vehicles sold in the USA. Some of the 1994-1995 OBD II systems were not fully compliant, so the Government granted waivers to give manufacturers time to fine-tune their systems. Beginning in 1996, most of the new vehicles sold in the USA were fully OBD II compliant.

DIAGNOSTIC LINK CONNECTORS (DLC)

The Data Link Connector (DLC) allows the scan tool to communicate with the vehicle’s computer(s). Before OBD II, manufacturers used different data link connectors to communicate with the vehicle. The proper DLC adapter cable must be used to connect the tool to the vehicle. Also, the vehicle’s DLC may be found in several different places and have many different configurations. The following describes the DLCs used by Ford, GM and Chrysler. The DLC location and types for domestic vehicles can be looked up in the charts in “Appendix

A - Data Link Connectors".

OBD II (J1962)

Beginning in 1996, vehicles sold in the United States use the J1962 (OBD II) DLC, a term taken from a physical and electrical specification number assigned by SAE (J1962). The DLC should be located under the dashboard on the driver side of the vehicle. If the DLC is not located under the dashboard as stated, a decal describing its location should be attached to the dashboard in the area the DLC should have been located.

Because the OBD II J1962 connector has power and ground, you only need a single cable connection to the tool for both power and tool communications. Attach the OBD II adapter cable to the extender cable, both supplied with the tool, to connect the tool. Certain pins in the connector are reserved

Vehicle Power

When using the OBD II J1962 or Chrysler LH adapter cables, the power to the tool comes from vehicle Data Link Connector (DLC). All other vehicles will require power connection to the cigarette lighter, accessory plug, or the vehicle battery using battery clip adapters. If you are unsure of what DLC adapter to use, then refer to “Appendix A - Data Link Connectors".

Some vehicle cigarette lighters are not powered when the ignition is in the OFF position. Therefore, you may wish to use battery clip adapters.

Using The Scan Tool

Printer Interface

The scan tool is designed as a Data Terminal Equipment (DTE) device with a DB9M (9-pin D-shape male) connector to interface with a compatible serial printer.

Compatible Printers

The printer must have a serial RS-232 interface circuit and be compatible with the Epson FX format. The following printers are recommended:

❒ Seiko DPU-414 ❒ Kodak DICONIX 180si (serial printer model) ❒ Lexmark Model 2480 with optional serial interface (p/n 12T0154) ❒ Panasonic KX-P1131 printer

Cabling

❒ Type: A standard RS-232 type cable. ❒ Scan Tool end: DB9F (female) connector. ❒ Printer end:

• Use a DB9M (male) connector for the Seiko and Kodak printers.

• Use a DB25 male connector for the Lexmark and Panasonic printers.

• If the printer uses a different connector, then an adapter or different RS-232 cable is required. Adapters are available at most local PC stores or electronics outlets.

Serial Port Settings

❒ Default settings for the scan tool are: 9600 Baud, 8 Data Bits, No Parity

and 1 Stop Bit.

❒ Ensure the settings on the scan tool and printer match. ❒ For the Lexmark and Panasonic printers, ensure the printer’s interface

selection is set to either “auto” or “serial”.

The printer and scan tool must have the same communication settings. You can change the scan tool’s settings if necessary.

✓ If vehicle communicates using a Controller Area Network (CAN), O2

Monitor tests are NOT supported by vehicle. A message is displayed. See Diagnostic Monitor Test to see O2 Monitor data.

OBDII regulations require applicable vehicles monitor and test 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). Sensors are named (xy) for their position to both cylinder banks and catalysts.

• The O2 sensor for cylinder bank 1 has prefix 1y while O2 sensor for cylinder bank 2 has prefix 2y.

• The O2 sensor upstream of catalyst (closest to engine) has suffix x1 while O2 sensor downstream of catalyst has suffix x2. If vehicle contains more catalysts, O2 sensor downstream of second catalyst has suffix x3 and O2 sensor downstream of next catalyst has suffix x4.

• For example, O2S21 is upstream O2 sensor for cylinder bank 2.

The following O2 sensor tests are available:

1) Rich to Lean sensor threshold voltage

2) Lean to Rich sensor threshold voltage

3) Low sensor voltage for switch time

4) High sensor voltage for switch time

GM HISTORIC (OBD I) DIAGNOSTICS

✓ Some 1994 and 1995 vehicles use the 16-pin OBD II connector, but are not

OBD II compliant. They still use the OBD I application software. Refer to “Appendix A - Data Link Connectors".

Manual Info

The Manual Info function instructs the user what section of the manual to use. This section covers GM Historic (OBD I) Diagnostics.

Read Codes

The Read Codes function is used to retrieve all stored Diagnostic Trouble Codes (DTCs) from the control module(s). This can be performed with key ON engine OFF (KOEO) or key ON engine RUNNING (KOER). Two types of codes were used by GM in the Historic System: Current codes and History codes. Prior to 1986, all codes were referred as Current Codes. From 1986 through 1995, both codes were used as the PCM was able to differentiate them.

The tool automatically displays the type of codes that pertain to the vehicle under test. The DTC types are defined as follows:

• History Codes — intermittent codes placed in the vehicle’s memory when the trouble originally occurred, and will remain there even if the trouble has been corrected. If no trouble after 50 engine warm-up cycles, the DTC erases.

• Current Codes — codes transmitted through the PCM’s data stream when a trouble condition is active and cannot be erased. The problem must be repaired to remove the DTC.

✓ On some vehicles, all codes are Current Codes, because the PCM cannot

distinguish Current Codes from History Codes. The only way to determine this is to erase the code and then drive the vehicle to see if the code returns.

Perform the following:

1) Set Parking Brake

2) Turn Key On-Engine Off or Running.

3) Put Transmission In Park Or Neutral.

The Erase Codes function deletes the DTCs from the vehicle’s computer memory. Perform this function with KOEO or KOER. This function should be performed only after the systems have been checked completely and DTCs have been documented.

After servicing the vehicle, erase the stored DTCs, perform a road test, and then verify no new codes have been stored. If DTCs return, the problem has not been corrected or other faults are present.

✓ Some codes can only be removed by repairing the faults that caused

them. Therefore, these codes will remain in the vehicle’s memory until the condition is repaired.

✓ Not all trouble codes can be automatically erased using the scan tool.

Some vehicles require a manual erasing procedure. If possible, the tool performs the appropriate Erase Codes procedure for your vehicle.

✓ The computer has a “learning” ability to compensate for minor variations

View Data

The View Data function allows the user to view the vehicle Parameter Identification Data (PIDs) in real time. As the PCM monitors PIDs, they are simultaneously transmitted to the scan tool. The PIDs are continuously updated at the PCM’s rate.

In addition to reading codes, View Data is the most useful diagnostic function for isolating the cause of a vehicle operation problem. Viewing data is also used for observing sensor data and the ON/OFF state of switches, solenoids, and relays.

View Data can be performed with the ignition key On-Engine Off or Running.

Field Service

Field Service is a special diagnostic mode to monitor fuel system operation and

read DTCs. Some GM service manuals may refer to this mode as the Field Service Mode Check. This mode works on vehicles equipped with a 12-pin ALDL connector with a wire present in Pin-B, Diagnostic or Test Enable. The scan tool enters this mode by grounding Pin-B: shorting Pin-B to Pin -A (ground).

Field Service Mode can be operated with the ignition Key On-Engine Off (KOEO) or with the Key On-Engine Running (KOER).

✓ Vehicles equipped with climate control computers do not use Field Service

Mode.

✓ Some 1994 & 1995 vehicles equipped with a 12-pin ALDL connector with

pins A and B shorted will not cause the CHECK ENGINE light to flash codes.

KOEO Procedure

In the KOEO Procedure, Field Service can check relays, solenoids and the idle speed motor, and obtain DTCs using the CHECK ENGINE light.

1) Turn ignition Key ON but DO NOT Start Engine.

2) On scan tool, place Field Service On.

3) The Check Engine light will begin to flash codes. Each DTC is displayed three (3) times. The DTCs are displayed starting with the lowest numbered one. After all DTCs are displayed, the sequence keeps repeating until the ignition key or Field Service mode is turned OFF.

— Count CHECK ENGINE Light Flashes to obtain trouble codes. The first

digit is sent first. A short pause separates digits while a long pause separates each DTC. All codes contain 2 digits.

— DTC 12 (No RPM reference pulse) should display first since the engine

is not running. If not, problems exist in the PCM or Check Engine light circuitry.

Code 12 will look like:

FLASH-pause-FLASH-FLASH — long pause.

Code 23 will look like:

FLASH-FLASH-pause-FLASH-FLASH-FLASH — long pause.

4) When Field Service Mode is ON, most computer controlled Relays and Solenoids will be turned ON, except for the fuel pump relay and fuel injectors. Toggle the Field Service Mode On and Off.

❒ Use a voltmeter to measure Relays and Solenoids input voltage to

verify On/Off conditions. An ohmmeter could be used to check the continuity between the relay’s switch terminals.

❒ The Idle Air Control (IAC) valve is fully seated to the zero position by

the PCM.

❒ The Exhaust Gas Recirculation (EGR) solenoid is energized for 25

seconds.

KOER Procedure

With the engine running, the Field Service mode can be used to measure base timing, check open loop/closed loop operation, and determine if the engine is running rich or lean.

1) Engage parking brake and block drive wheels.

2) Verify engine is cold. If engine is hot or warm, allow it to cool.

3) On scan tool, place Field Service On.

4) Start engine and place transmission in Park or Neutral. The Check Engine light will flash once.

5) Warm the engine by idling for 2 minutes at 2000 RPM.

6) Observe Check Engine light.

• If Check Engine light flashes 2.5 times a second, the on-board computer is operating in Open Loop.

• When the engine warms up to normal operating temperature, the on-board computer is now operating in Closed Loop. The Check Engine light should flash once a second. The on-board computer is now operating in Closed Loop.

• If Check Engine light...

— flashes equally ON/OFF, then the fuel system is running normally. — is mostly ON, then the fuel system is running Rich. — is mostly OFF, then the fuel system is running Lean.

7) On some engines, the spark advance timing is fixed during Field Service Mode. This allows the technician to measure the engine base timing.

IMPORTANT

This system applies to GM vehicles manufactured from 1996 to present. Some GM vehicles in 1994 and 1995 were equipped with this system. Refer to “Appendix A - Data Link Connectors". GM vehicles manufactured from 2002 to present automatically use Global OBD II Diagnostics.

✓ If an Error Message displays, make sure the OBD II connector is

securely attached, and the ignition key is ON. Cycle the ignition key to OFF for 10 seconds, then ON. This may be required to reset the computer. If required, select YES to try again. If the problem still exists, refer to “Error Messages” on page 8-2.

✓ Specific GM Enhanced functions are defined in this section. Refer to

“Section 4 - Global OBDII Diagnostics" for other functions.

Manual Info

The Manual Info function, instructs the user what section of the manual to use. This section covers GM Enhanced (OBD II) Diagnostics.

Refer to “” on page 4-1 of Global OBDII Diagnostics.

Read Codes

The Read Codes function retrieves Diagnostic Trouble Codes (DTCs) from the vehicle’s computer module(s). This function can be performed with the KOEO or KOER. These codes cause the computer to illuminate the Malfunction Indicator Lamp (MIL) when an emission-related or driveability fault occurs. The MIL is also known as the “service engine soon” or “check engine” lamp.

The GM Enhanced reads DTC’s from the engine or powertrain module (ENG), Transmission Module (Trans), or Transfer Case Module (XFER).

Not all GM vehicles support DTC status. Some only use the Global OBDII Read Codes command. For a description of these screens, refer to the Global OBDII section of the manual.

• Current Codes — codes transmitted through the PCM’s data stream when a trouble condition is active and cannot be erased. The problem must be repaired to remove the DTC.

• Intermittent Codes — indicates the current code has been set at least once but possibly not enough to cause a history code to be stored.

• Pending Codes - These are codes that are developing, but are not quite a Current Code.

In GM Enhanced OBD II, if DTCs are present, then three conditions (or statuses) may accompany each DTC definition.

GM Code Types:

• MIL (Malfunction Indicator Lamp): REQUESTED or NOT REQUESTED An emissions-related DTC is requesting the MIL (Check Engine/Service

Engine Soon) to be ON.

• Since IGN (ignition): PASS, FAIL, P/F, or NOT RUN Provides the DTC status during this power-up. P/F (Pass/Fail) indicates the

PCM detected the DTC that passed and failed at least once during this power-up cycle. NOT RUN means the PCM has not tested for the condition that set the DTC during this power-up cycle.

• Since Clear: PASS, FAIL, P/F, or NOT RUN Provides the DTC status since the last time the codes were erased. P/F indicates the PCM test that detected the DTC passed and failed at least once since the last Erase Code. NOT RUN means the PCM has not tested for the condition that set the DTC since the last Erase Code.

FORD HISTORIC SELF-TEST ROUTINES

Due to different processor calibrations, the Ford Function List for a particular vehicle may or may not appear as shown. Based on the vehicle information entered at the Vehicle Setup menu, the tool automatically recognizes the computer system installed.

If the function is not supported by the vehicle, than the scan tool does not display it.

✓ Ford vehicles manufactured from 2002 to present automatically use Global

OBD II Diagnostics.

✓ Most Ford vehicles prior to 1996 use the EEC-IV system. Vehicles with

Mazda-sourced engines use the Mazda Electronic Control System (MECS). Refer to “Appendix A - Data Link Connectors".

✓ If the Scan Tool displays an Error Message, make sure the adapter cable

is securely attached and the ignition key is ON. Cycle the ignition key to OFF for 10 seconds, then ON. This may be required because the Ford system allows only one Self-Test function to be performed for each Key ON. Attempt the test selected again and if the problem remains, refer to “Error Messages” on page 8-2.

Manual Info

The Manual Info function instructs the user what section of the manual to use. This section covers Ford Historic Self-Test Routines

Read KOEO Codes

The Read KOEO Codes function activates the KOEO (Key On Engine Off) and Continuous Memory self-tests which retrieves KOEO and Continuous Memory DTCs from the PCM.

• KOEO DTCs are transmitted through the PCM data link when a trouble condition is active. KOEO codes remain until the trouble condition becomes inactive – usually when the fault is repaired.

• Continuous Memory DTCs are stored in vehicle’s memory at the time of occurrence during continuous self-test monitoring. They will remain there until the problem does not reoccur within 40 warm-up cycles, Fast KOEO codes have been read, or the Erase Codes function has been run. Continuous memory codes follow the KOEO codes in the data stream.

The DTCs are transmitted in two formats; both transmit the same information:

• Slow Codes are regular service codes that allow the user to identify the faults with an analog voltmeter or the check engine light. Slow codes are transmitted within 3 minutes.

• Fast Codes are transmitted within seconds and must be read with a diagnostic tool. Retrieving Fast Codes erases Continuous Memory Codes, Slow Codes does not. Fast Codes do not apply to MECS vehicles.

Erase Codes

The vehicle service manual may recommend erasing Continuous Memory Codes from vehicle’s memory, and then driving vehicle to duplicate the malfunction before beginning a diagnostic test. If KOEO codes were read using Fast Codes, the memory codes have already been erased.

Only Continuous Memory Codes can be erased from the vehicle without repairing the fault. To remove KOEO and KOER Codes, the fault must be repaired since they only exist when a fault exists.

Cylinder (Cyl) Balance Test (EEC-IV Vehicles)

✓ The Cyl Balance Test is only applicable to engines equipped with EEC-IV

Sequential Electronic Fuel Injection (SEFI or SFI) .

The Cyl Balance Test identifies a weak cylinder(s) on EEC-IV vehicles. A weak cylinder may be caused by low compression, poor valve seating, fouled spark plugs, damaged fuel injectors, and other cylinder faults. The PCM shuts off the fuel supply to each cylinder and measures the RPM drop. The PCM then calculates variations between cylinders thus identifying the weak ones.

Refer to “Erase Codes” on page 4-5 of Global OBDII Diagnostics. Perform this KOEO. After erasing the DTCs, verify new ones have not been set using the Read All DTC function.

IMPORTANT

View Data

The View Data function allows you to view the vehicle’s Parameter Identification (PID) data in real time. As the computer monitors the vehicle, the information is simultaneously transmitted to the scan tool. Apart from Read Codes, View Data is the most useful diagnostic function for isolating the cause of a vehicle driveability problem. View data is also used for observing sensor data and the status of switches, solenoids, and relays.

Select View Data from the Ford Function List and press

Ford arranges the PIDs in six groups:

❒ Standard Info: viewing of analog

sensor signals, such as measured voltage from O2 sensors, temperature sensors, and air flow sensors.

❒ O2 Sensor Info: viewing oxygen sensor information. ❒ Misfire Info: viewing of cylinder misfire information. ❒ Auto Trans Info: viewing of automatic transmission information. ❒ Man Trans Info: viewing of manual transmission information. ❒ A/C Info: viewing of air conditioning information.

Until all monitors have ran the absence of a Diagnostic Trouble Code (DTC) does not mean the fault has been fixed.
