Co oznacza ten kod błędu?
Over CAN, the ECM tells the BCM whether its engine speed reading is valid. The BCM uses the engine speed signal when regulating the stability function. The code is set when the engine control module reports that the engine speed signal is implausible. It only applies to cars with STC/DSTC and can be read once the engine has been started.
Możliwe przyczyny
- Fault in the engine control module (ECM)
Co możesz zrobić
- 1Read codes in the central electronic module first and troubleshoot them
- 2Read codes in the engine control module and troubleshoot them according to their information
- 3Do not replace the brake control module for this code, as the fault is engine-related
- 4The brake and stability systems are safety-critical, so have a workshop carry out any work on the engine management and the brake control module
