What does this fault code mean?
The brake pressure sensor at the front left wheel sends two output signals to the brake control module: one for pressure and one combined signal for pressure and temperature in the brake fluid. The code is set when one of the sensor's output signals is outside the permitted range, so the pressure in that circuit cannot be trusted.
Possible causes
- Damaged front left brake pressure sensor
- Internal fault in the brake control module
What you can do
- 1With diagnostic equipment establish whether the sensor or the brake control module is at fault, and replace the brake control module if the fault remains
- 2After replacing the brake control module, the workshop must recalibrate the internal sensors, as the acceleration sensor (IMU) also needs it
- 3Switch the ignition on and choose to continue the calibration when the system asks
- 4The brake system is safety-critical, so have a workshop carry out all work on the sensor and the module
Symptoms you may notice4
- Hill descent assist does not work
- Front monitoring and adaptive cruise control do not work
- Hill start assist does not work
- Traction control does not work
