Diagnostic Mode 02: Obtain operating conditions
WARNING: This page is about a different car, the 2009 Audi S6, 2008 Audi S6, and 2007 Audi S6. However, it is still accessible from the selected car via links, so may be relevant.
Diagnostic Mode 02 is used to monitor the operating conditions under which the Engine Control Module (ECM) has detected and stored an emissions related DTC.
NOTE:
- Depending on scan tool and protocol used, the information in diagnostic mode 02 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), or On-Board Diagnostic Monitor Identifier (OBDMID).
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 2: Obtain operating conditions.".
- From the following table, select the desired the "PID", e.g. "PID 05-Coolant temperature" that is to be monitored.
NOTE:
- More than one "PID" may be selected and monitored.
The current values of the component or system that is being monitored will be displayed on the scan tool screen.
