Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-U002855

Condition
The control modules in the vehicle send and receive information continuously on the vehicle's controller area network (CAN).
The Supplemental restraint system module (SRS) is the main system in a local network, sensor-CAN, that both transmits and receives information via a standardised serial communication protocol - CAN (Controller Area Network). The local network can have several different control modules connected (market dependent).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Signal configuration-ID in Brake control module (BCM) differs from the signal configuration-ID that Supplemental restraint system module (SRS) sends out on the local network.

Note! This fault code is set regardless of on which network the problem is located.

The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on.
- Ignition on for at least 7 seconds.

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.

Hint: Brake system, abbreviations Brake System, Abbreviations

Possible source
- Incorrect configuration ID (the control module is not intended for this vehicle, for example it is a used control module with different software/hardware).
