Diagnostic Mode 06 - Read Test Results For Specific Diagnostic Functions: Notes
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 in Diagnostic Mode 06 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), or On-Board Diagnostic Monitor Identifier (OBDMID).
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.
-- Select "Diagnostic Mode 06 - Check Test Results of Components that are not Continuously Monitored".
-- Select the desired "Test-ID" of the component or system that is to be monitored, e.g. "Test-ID 01: 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.
