Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information SRS-U012100

Condition
The control module is continually supplied with necessary information from the Brake control module (BCM) via CAN communication. The control module checks the communication with the Brake control module (BCM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- No communication with the Brake control module (BCM).
- Incorrect value runs longer than 2.5 seconds.
The control module's test for the diagnostic trouble code (DTC) starts when:
- Ignition position II and III.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- None.

Possible source
- Fault-trace in transmitting control module.
