Was bedeutet der Fehlercode?
The current is too high in at least one of the phases feeding the electric rear axle (ERAD). The code is set while driving in gear D or R. The fault may lie in the high voltage cable connection, in the wiring between the ERAD and the voltage converter (ISC), or in the ISC itself. Electric propulsion is then not possible.
Mögliche Ursachen
- High voltage cable not connected or poorly connected to the voltage converter (ISC)
- Loose contacts, contact resistance or oxidation at the connections between the ERAD and the ISC
- Open circuit in the high voltage cable
- High voltage cable short-circuited to ground
- Damaged wiring between the ERAD and the ISC
- Internal fault in the voltage converter (ISC)
Was Sie tun können
- 1Have a workshop check the high voltage cable connection to the voltage converter (ISC) and the wiring to the electric rear axle. High voltage systems may only be handled by qualified personnel
- 2If you have a diagnostic tool: compare the current in the different phases in live data during a drive in gear D or R
- 3Do not work on the high voltage cabling yourself
- 4After the repair, check that the code is not stored again while driving
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
