Co oznacza ten kod błędu?
The electric rear axle drive module (IEM) is expected to respond quickly to the engine control module's (ECM) request to reduce torque. Although the code is named checksum, it relates to the control module reacting too slowly to that request. 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)
- 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
- 2Have a workshop with diagnostic equipment check whether new software is available for the control module and download it if needed
- 3Do not work on the electric rear axle or its high voltage system yourself; have a workshop carry out those checks
