Possible causes

What you can do

- 2Read the fault codes in the central electronic module (CEM) and see whether it holds codes for missing communication with other control modules
- 3Have a workshop fault-trace the CAN communication between the BCM and the CEM
- 4Do not work on the brake system or the brake control module yourself; leave this to a workshop
