Co oznacza ten kod błędu?
The electric rear axle drive module (IEM) keeps watch over the electric rear axle ERAD. The code is stored when the torque in ERAD is too high at idle. The fault is only checked once the car is driven in gear D or R.
Możliwe przyczyny
- Software error in the electric rear axle drive module (IEM)
- The clutch in ERAD has mechanical damage
- The electric rear axle ERAD is damaged
Co możesz zrobić
- 1Read out, note and clear the code, then road test in D or R to see whether it returns
- 2If you have diagnostic equipment: follow the torque of ERAD in live data while the car rolls in D or R and see whether it clearly deviates from what is requested
- 3Have a workshop check whether new software is available for the control module, and check the electric rear axle and the clutch in ERAD, as they may be mechanically damaged
- 4Do not work on the electric rear axle or its high voltage system yourself; have a workshop carry out those checks
Objawy, które możesz zauważyć4
- Warning symbol and text message in the display
- PURE drive mode disengages by itself or is not available
- AWD drive mode disengages by itself or is not available
- HYBRID drive mode runs with the combustion engine active all the time or too often
Na co może wpływać usterka2
- Electric propulsion is not possible
- Brake energy regeneration from the electric rear axle ERAD is not possible
