Co oznacza ten kod błędu?
The code concerns a temperature sensor inside the electric rear axle drive control module (IEM). The sensors measure the temperature of the high voltage transistors inside the control unit. The signal from one or more sensors is too low, which may correspond to a short to ground in the sensor. The fault is set with the ignition on once the control module's test has started. Electric propulsion is then not possible.
Możliwe przyczyny
- A temperature sensor inside the IEM is damaged
- Internal fault in the voltage converter (ISC)
Co możesz zrobić
- 1If you have a diagnostic tool: read the temperature values in the IEM in live data and see whether any of them stays constantly low
- 2Have a workshop check the electric rear axle drive control module, since the sensors are inside it. High voltage systems may only be handled by qualified personnel
- 3Do not carry out any work inside the electric rear axle drive control module yourself
- 4After the repair, check that the code is not stored again
Objawy, które możesz zauważyć4
- Warning window with a warning symbol and text message
- Drive mode PURE disengages automatically or is unavailable
- Drive mode AWD disengages automatically or is unavailable
- Drive mode HYBRID: the combustion engine runs all the time or too often
Na co może wpływać usterka2
- Electric propulsion is not possible
- Brake energy regeneration from the electric rear axle is not possible
