Co oznacza ten kod błędu?
The transmission control module has registered that the system voltage is too high. It compares the voltage with the value that the central electronic control module (CEM) sends on the CAN network. The cause may be a battery charger with the wrong voltage, or an internal fault in the transmission control module.
Możliwe przyczyny
- A battery charger with the wrong voltage has been used
- Internal fault in the transmission control module
Co możesz zrobić
- 1Read the fault code, clear it and road test the car to see whether it comes back
- 2If you have diagnostic equipment, read the voltage in live data with the engine idling and compare it with the battery
- 3Check that the battery terminals are tight and that no battery charger is connected
- 4Have a workshop check the charging system for too high a charging voltage and troubleshoot the CEM if no fault is found
- 5Have a workshop replace the transmission control module if it has an internal fault
Objawy, które możesz zauważyć2
