What does this fault code mean?
The brake control module (BCM) is not in contact with the electronic parking brake control module (PBM) on the CAN network. The parking brake may then have reduced function. The fault most often comes from interference or intermittent breaks on the network.
Possible causes
- Interference or intermittent breaks on the CAN network
- Fault in the parking brake control module (PBM)
What you can do
- 1Read codes in the central electronic module and other affected modules, and correct them first
- 2If no codes are stored, check the wiring and connectors on the CAN network for breaks and contact resistance
- 3Check that the wiring is not routed close to sources of interference, such as mobile phones
- 4Clear the code only once the other faults are corrected, and check that the parking brake applies and releases as it should
- 5The brake system is safety-critical, so have a workshop carry out any work on the wiring and the modules
Symptoms you may notice2
- The electronic parking brake has reduced function
- The parking brake does not work, works with reduced function or works incorrectly
