Co oznacza ten kod błędu?
The engine control module monitors CAN traffic between itself and the transmission control module (TCM). The code is set in two ways: when the TCM asks for the malfunction indicator lamp to flash, which counts as a faulty signal, or when that lamp signal is absent from the CAN network. Either way, the fault most likely lies in the transmission control module.
Możliwe przyczyny
- The TCM sends a request for the malfunction indicator lamp to flash
- The lamp signal from the transmission control module is absent from the CAN network
Co możesz zrobić
- 1Read the fault codes in the transmission control module (TCM) first, then in the central electronic module (CEM)
- 2Fault-trace and remedy the TCM faults and the CAN codes in the CEM before clearing this code
- 3Check the connectors and CAN wiring to the transmission control module for open circuits and chafing
- 4Clear the fault code once the faults are remedied and road test the car to see whether it returns
Objawy, które możesz zauważyć1
