Fault-tracing information
The diagnostic trouble code (DTC) can be generated in some cases after the brake control module (BCM) has been reprogrammed. If this is the case, the brake control module (BCM) must be configured.
Was the diagnostic trouble code (DTC) generated after the brake control module (BCM) was reprogrammed?
Yes - Checking the car configuration
No - Checking diagnostic trouble codes (DTCs) in the central electronic module (CEM)
-------------------------------------------------
Checking diagnostic trouble codes (DTCs) in the central electronic module (CEM)
Note! If the central electronic module (CEM) is incorrectly configured it may affect the brake control module (BCM). Fault-trace the central electronic module (CEM) first if there are diagnostic trouble codes (DTCs) stored in both the control modules.
- Ignition on
- Read off diagnostic trouble codes (DTCs).
Are diagnostic trouble codes (DTCs) stored in the central electronic module (CEM)?
Yes - DONE
No - Checking the software
-------------------------------------------------
Checking the software
- Ignition on
- Read off the software version from the brake control module (BCM).
Check that the diagnostic number corresponds to the car configuration. If the software does not correspond to the car configuration, make a bookmark and cancel the fault-tracing. Then go to the software manager and download the correct software. Then resume the fault-tracing.
Was the control module programmed with the correct software?
Yes - Checking the car configuration
No - Erasing diagnostic trouble codes (DTCs)
-------------------------------------------------
Erasing diagnostic trouble codes (DTCs)
- Ignition on
- Erase diagnostic trouble codes (DTCs) from the brake control module (BCM).
Continue - Reading off diagnostic trouble codes (DTCs)
-------------------------------------------------
Reading off diagnostic trouble codes (DTCs)
- Ignition off
- Wait approximately 15 seconds.
- Ignition on
- Read off diagnostic trouble codes (DTCs).
Is diagnostic trouble code (DTC) BCM-0076 stored?
Yes - Checking the car configuration
No - Fault Found
-------------------------------------------------
Checking the car configuration
- Ignition on
- Read off the car configuration from the central electronic module (CEM).
Check that the all the car functions are in the list, e.g. type of brake system, four wheel drive etc. See the example below for cars with DSTC.
Anti-lock brakes = ABS DSTC.
Does the car equipment correspond to the car configuration?
Yes - No Fault Found
No - Checking the brake system
-------------------------------------------------
Checking the brake system
Does the car have TRACS, STC or DSTC?
Yes - Resetting and configuring the brake control module (BCM)
No - Resetting and configuring the control module
-------------------------------------------------
Resetting and configuring the brake control module (BCM)
- Ignition on
- Reset the configuration
- Wait 1 minute.
Continue - Fault-tracing information
-------------------------------------------------
Resetting and configuring the control module
