Diagnostic Mode 02 - Obtain Operating Conditions
WARNING: This page is about a different variant/trim than selected.
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.
