Part 2

Diagnostic Modes 01 - 09

- Check specified values at idle.

- If any of components or systems fail to meet the specified values. Refer to Diagnostic "Mode 03: Interrogating Fault Memory" to check for stored DTC or the corresponding diagnostic repair procedure => [ Diagnostic Mode 03 - Read DTC Memory ].

- Switch the ignition off.

- If any of the components or systems fail to meet the specified values, refer to Diagnostic Mode 03: Interrogating Fault Memory to check for stored DTCs or the corresponding diagnostic repair procedure.

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.

• 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.

• 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.

- Refer to the DTC tables for the diagnostic repair procedures.

- Switch the ignition off.

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.

Test requirements

• No DTCs stored in the DTC memory.

• Intake Air Temperature (IAT) maximum 60 °C.

• Coolant temperature 80 -110 °C.

• Throttle valve angle 12.0 - 16.0%.

Function test

• 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 "Mode 8: Tank Leak Test".

- Select "Test-ID 01: Tank Leak Test".

- Check the specified value of the tank leak test at idle.

- The following will be displayed on the scan tool screen:

- 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 => [ Evaporative System, Checking for Leaks ] Evaporative System, Checking for Leaks.

Diagnostic Mode 09 - Read Vehicle Information

Diagnostic Mode 09 makes it possible to access vehicle-specific information from the ECM and the TCM (where applicable).

• Depending on scan tool and protocol used, Diagnostic Mode 09 and the information provided may be referred to by a different name.

Test requirement

• No DTCs stored in the DTC memory.

Procedure

- Connect the scan tool.

- Switch the ignition on.

- Select Mode 09: Vehicle information.

- Select the desired Test-ID.

- The information requested will be displayed on the scan tool screen.

The following table is a numerical list of all Test-IDs that may be selected.

- Switch the ignition off.
