Co oznacza ten kod błędu?
On the V60, the brake control module (BCM) has requested a certain pressure build-up in the secondary brake circuit, but the measured pressure does not reach it. This points to a damaged hydraulic pump or an internal fault in the hydraulic system.
Możliwe przyczyny
- Damaged hydraulic pump
- Internal fault in the hydraulic system
Co możesz zrobić
- 1Read and note the code, clear it and road test the car to see whether it returns
- 2Check the brake pipes and joints running to the module for any damage
- 3Check the hydraulic pump and the hydraulic system with diagnostic equipment
- 4If the fault returns, the brake control module needs replacing by a workshop, and the acceleration sensor and internal sensors must then be calibrated
- 5The braking system is safety critical: do not work on the hydraulic system or pump yourself; leave this to a workshop
Objawy, które możesz zauważyć4
