Was bedeutet der Fehlercode?

The transmission control module compares the system voltage with the value that the central electronic control module (CEM) sends on the CAN network. The code is set when the values do not match, and this can be caused by poor contact, a battery charger with the wrong voltage, or an internal fault in the transmission control module.

Mögliche Ursachen

Poor contact or oxidation at the transmission module connector or in the gearbox
A battery charger with the wrong voltage has been used
Internal fault in the transmission control module

Was Sie tun können

1If you have diagnostic equipment, compare the voltage at the transmission control module with the CEM value in live data; they should be roughly equal
2Check the connector to the transmission control module for contact resistance and oxidation
3If a battery charger has been connected to the car, check that it has the correct voltage for the car
4If no fault is found in the connector, have a workshop troubleshoot the CEM
5Have a workshop replace the transmission control module if it has an internal fault
