GENERIC SCAN TOOL MANUAL CONTENTS
"GST" is an acronym for Generic Scan Tool Manual.
Included in the contents of this GST manual is a summary table of the vehicle specific OBD II Emission Related Engine and Transmission DTCs. This table contains all necessary Malfunction Criteria, Threshold Values, Secondary Parameters, Enabling Conditions, Monitoring Time Length, Frequency of Checks, and MIL Illumination to accurately monitor and diagnose the Engine Emissions and Transmission and perform all functions required to run Modes 01 through 09 with a hand held scan tool. For a further description of the monitor strategies, a document reference has been provided throughout this GST manual to the applicable OBD System Strategy document.
This GST manual also contains the step by step pin point test procedures to accurately diagnose the suspected component or system once a DTC has been set. All references to repair procedures and wiring diagrams will be found within the diagnostic test procedure.
DIAGNOSTIC MODES
The information provided in Modes 01 through 09 displays the various levels of emission related data that may be monitored, as well as the ability to retrieve and read stored DTC trouble codes , erase stored DTC trouble codes, generate readiness codes, and select the various PIDs and Test-IDs used within the modes to monitor the engine, and emission related component parameters.
Note. Depending on scan tool and protocol used, the information displayed may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a number.
The following table provides a link to all diagnostic modes that monitor all components and systems which influence the emission quality.

DIAGNOSTIC MODE 02 - READ OPERATING CONDITIONS
When an emissions-related fault (pending DTC, visible in mode 07) is first detected, operating conditions are stored. Mode 02 makes it possible to access this freeze frame data as soon as this fault is shown in mode 03. Each control module only shows freeze frame data for one fault via mode 02. Therefore, there are two priority levels. If there is a malfunction with higher priority, the freeze frame data is overwritten.
Fault with higher priority: Misfire malfunction or fuel trim malfunction.
Fault with normal priority: All other emissions-related faults.
Depending on scan tool and protocol used, the information displayed in diagnostic mode 02 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a number.
Procedure
Connect the scan tool.
Start the engine and run at idle.
Note. If the engine does not start, crank the engine using starter for at least 5 seconds, do not switch the ignition off afterward under any circumstances.
Select "Diagnostic Mode 02 - Obtain Operating Conditions".
From the following table, select the desired the "PID" , e.g. "PID 05 Coolant temperature" that is to be monitored.
The current values of the component or system that is being monitored will be displayed on the scan tool screen.

End of procedure.
DIAGNOSTIC MODE 03 - READ DTC MEMORY
Diagnostic Mode 03 makes it possible to read emissions-related faults (confirmed DTCs: faults which have activated the MIL) in the ECM and in the TCM.
When the Engine Control Module (ECM) -- recognizes an emission related fault it turns on the Malfunction Indicator Lamp (MIL) -- or if a Electronic Throttle Malfunction is recognized, the Engine Control Module (ECM) -- turns on the Electronic Power Control (EPC) Warning Lamp -- which are both located in the instrument cluster.
The DTC's are sorted by SAE code with the DTC tables consisting of a 5-digit alpha-numeric value.
Depending on scan tool and protocol used, the information displayed in diagnostic mode 03 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a number.

- Number of DTCs
- Readiness Bits
- Confirmed DTCs
- Pending DTCs
- DTC that belongs to freeze frame
- Freeze frame data

End of procedure.
DIAGNOSTIC MODE 06 - READ TEST RESULTS FOR SPECIFIC DIAGNOSTIC FUNCTIONS
Diagnostic Mode 06 makes it possible to retrieve test results for special components and systems which are continuously or not continuously monitored. If the diagnosis of a system is complete, the diagnostic result and the corresponding thresholds are saved and displayed in mode 06. This data remains saved (even with the ignition off) until either new diagnostic results become available or the DTC memory is erased.
The values of the individual test results must reach the specified value or must be within the min. and max. limits.
Depending on scan tool and protocol used, the information displayed in diagnostic mode 06 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a number.

DIAGNOSTIC MODE 07 - READ FAULTS DETECTED DURING THE CURRENT OR LAST DRIVING CYCLE
Mode 07 makes it possible to check emissions-related faults which appeared during the current or last driving cycle (pending DTCs).
A pending DTC is saved the first time a fault is detected (output via Mode 07).
If the fault is detected again by the end of the following driving cycle, a confirmed DTC is entered (output via Mode 03) and the MIL is activated.
If this malfunction is not detected again by the end of the following driving cycle, the corresponding pending code will be deleted at the end of the driving cycle.
Note. Depending on scan tool and protocol used, some of the information provided may be referred to by a different name.
Procedure
Connect the scan tool.
Start the engine and run at idle.
Note. If the engine does not start, crank the engine using starter for at least 5 seconds. Do not switch the ignition off afterward.
Select "Mode 7: Check test results of components that are continuously monitored".
The number of pending DTCs or "0 malfunctions detected" will be displayed on the scan tool screen.

DIAGNOSTIC MODE 08 - REQUEST CONTROL OF ON-BOARD SYSTEM, TEST OR COMPONENT
Diagnostic Mode 08 is used to control the operation of an on-board system, test or component. A Mode 8 service can be used to turn on-board system ON or OFF, or to cycle an on-board system, test or component ON or OFF for a specific period of time. The service can also be used to request system status or to report test results.
Diagnostic Mode 08, TID $01
Diagnostic Mode 08, TID $01 is used to determine if the evaporative system may be leaking.
Depending on the scan tool being used, the function test in Diagnostic Mode 08 may or may not be able to be performed.
If the scan tool being used will operate Diagnostic Mode 08, perform the test below FUNCTION TEST .
If the scan tool being used will not operate Diagnostic Mode 08, refer to EVAP SYSTEM, CHECKING FOR LEAKS .
Note. Always follow the manufacturers instructions for the scan tool being used.

FUNCTION TEST
Note. If the accelerator pedal is depressed during the test, the test will be aborted.
Connect the scan tool.
Start the engine and run at idle for at least 15 minutes.
Select "Diagnostic Mode 08 - Tank Leak Test".
Select " Tank Leak Test".
Check the specified value of the tank leak test at idle.
The following may be displayed on the scan tool screen
| Tank leak test | Specified value | |||||
|---|---|---|---|---|---|---|
| Test function active Test function is being initiated, please wait Test off Test aborted | Test OK | |||||
Switch the ignition off.
If the specified result is obtained
System OK.
If the specified result is not obtained
Repeat the tank leak test, switch the ignition off and start the engine again and let run for 15 minutes at idle.
Switch the ignition off.
If the specified result is again not obtained
A leak may be present. Refer to EVAP SYSTEM, CHECKING FOR LEAKS .
End diagnosis.
DIAGNOSTIC MODE 09 - READ VEHICLE INFORMATION
