Was bedeutet der Fehlercode?
Wheel tyre pressure is estimated mostly from wheel speed sensor data inside the BCM. The code is set when the checksum of the calibration area, after the data has been stored, does not match the calculated value. The indirect tyre pressure monitoring is then switched off.
Mögliche Ursachen
- Software fault in the brake control module
- Internal fault in the brake control module
Was Sie tun können
- 1Replace the brake control module if the fault remains after the code has been cleared
- 2After replacement the new module must be configured and calibrated by a workshop
- 3The brake system is safety-critical, so have a workshop carry out the replacement and check the function
