Was bedeutet der Fehlercode?
The code indicates that the voltage in the high voltage system is above what the electric rear axle drive control module (IEM) expects. Electric propulsion is then not possible. The fault may lie in the high voltage battery, in the connections between the battery and the voltage converter, or in one of the control modules.
Mögliche Ursachen
- The high voltage battery is overcharged
- Loose contacts, contact resistance or oxidation where the high voltage battery meets the voltage converter (ISC)
- Damaged wiring between the high voltage battery and the electric compressor control module (ACCM)
- Internal fault in the electric compressor control module (ACCM)
- Internal fault in the voltage converter (ISC)
- Internal fault in the high voltage battery
Was Sie tun können
- 1Have a workshop check the high voltage battery and its connections to the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
- 2If you have a diagnostic tool: read the high voltage system voltage in live data and see whether it is higher than expected
- 3Do not carry out any work on the high voltage system yourself
- 4After the repair, read out the fault codes and check that the code is not stored again
Symptome, die Sie bemerken können4
- Text window and warning symbol with a 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
Was der Fehler beeinflussen kann2
- Electric propulsion is not possible
- Brake energy regeneration from the electric rear axle is not possible
Allgemeine Hinweise für Fahrzeughalter. Die Diagnose am Fahrzeug kann eine andere Ursache zeigen.
