Co oznacza ten kod błędu?
The signal from the angle sensor in the electric rear axle (ERAD) is incorrect. The electric rear axle drive control module (IEM) sets the code while driving in gear D or R. The fault may lie in the wiring between the ERAD and the voltage converter (ISC), in the sensor, or in the ISC. Electric propulsion is then not possible.
Możliwe przyczyny
- Loose contacts, contact resistance or oxidation at the connections between the ERAD and the voltage converter (ISC)
- Open circuit in the signal cable
- Signal cable short-circuited to supply voltage
- Damaged wiring between the ERAD and the ISC
- Internal fault in the electric rear axle (ERAD)
- Internal fault in the voltage converter (ISC)
Co możesz zrobić
- 1Have a workshop check the connections between the electric rear axle and the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
- 2If you have a diagnostic tool: note whether the rotor sensor value disappears or stays constant while driving in gear D or R
- 3Do not work on the wiring to the electric rear axle yourself
- 4After the repair, read out the fault codes and check that the code is not stored again
Objawy, które możesz zauważyć4

- 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
