Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-U045286

Condition
The control module is continuously supplied with necessary information from the Supplemental restraint system module (SRS) via communication on the sensor-CAN. The control module checks the quality of the information coming from the Supplemental restraint system module (SRS).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The transmitting control module indicates a lower quality level of information than Brake control module (BCM) accepts.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

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.
