Diagnostic Trouble Code (DTC) Information Bpm-B101

Condition 

The control module compares its configuration ID with the signal configuration transmitted on the control area network (CAN) by the central electronic module (CEM).

The diagnostic trouble code (DTC) is stored if the control module detects that:

• At least one parameter in the vehicle configuration file is incorrect.

The control module's test for the diagnostic trouble code (DTC) starts in the event of:

• Ignition on and battery voltage between 9 and 16 V.
• Ignition on for at least 60 seconds.
