Diagnostic Mode 05: Check lambda test results: Notes
Diagnostic Mode 05 allows access to the Oxygen Sensor test results. Mode 05 is divided into test identifiers (TIDS).
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 05 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.
Test requirements
- Exhaust system must be properly sealed between the catalytic converter and the cylinder heads.
- No DTCs stored in the DTC memory.
- Coolant temperature at least 80°C.
Work 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 "Mode 5: Check lambda test results.".
- Select the desired "Test-ID" of the component or system that is to be monitored, e.g. "Test-ID 08: Oxygen Sensor Monitor Bank 1 - Sensor 1".
- Select the desired "Test-ID".
The current minimum and maximum values will be displayed on the scan tool screen.
The following table is a numerical list of all "Test-IDs" or "Hex-IDs" that may be selected.
| Test-ID (Hex-ID) | Component or System |
|---|---|
| "Test A" : : Test results for Oxygen Sensor Monitor Bank 1 - Sensor 1 under Diagnostic Mode 05: Check lambda test results | Test results for Oxygen Sensor In Front of Catalytic Converter Bank 1 - Sensor 1 |
| "Test A" : : Test results for Oxygen Sensor Monitor Bank 1- Sensor 2 under Diagnostic Mode 05: Check lambda test results | Test results for Oxygen Sensor Behind Catalytic Convertor Bank 1 - Sensor 2 |
