Co oznacza ten kod błędu?
The electric rear axle drive module (IEM) compares the calculated torque with the requested torque. If the difference becomes too large, the code is stored. The fault is only checked once the car is driven in gear D or R, and the code is stored when the conditions are met.
Możliwe przyczyny
- Software error in the electric rear axle drive module (IEM)
- Internal fault inside the ISC voltage converter
Co możesz zrobić
- 1Read out, clear the code and road test in D or R to see whether it returns
- 2If you have diagnostic equipment: check in live data that the calculated and requested torque for ERAD follow each other while driving
- 3Have a workshop with diagnostic equipment check whether new software is available for the control module and install it if needed
- 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
