What does this fault code mean?
The parking brake control module (PBM) checks its own system voltage when a function is activated. The fault code is stored when the voltage has an incorrect value for a longer time. The cause is that the supply voltage to the control module is too low.
Possible causes
- Supply voltage to the control module too low
What you can do
- 1Check that the battery voltage is correct; a weak or discharged battery can give too low a supply voltage
- 2Check that the fuse for the parking brake is intact
- 3Check that the battery terminals and earth connections are firmly fitted and not corroded
- 4After checking the battery: apply the parking brake, then clear the fault code, in that order, and check whether it returns
- 5If the fault returns, have a workshop check the supply to the parking brake control module (PBM)
- 6The parking brake is a safety function: have a workshop check it if it does not work as it should
Symptoms you may notice4
- The parking brake lamp flashes when the function is activated
- Information lamp is on
- Message in the text display
- Electric parking brake does not work
