Co oznacza ten kod błędu?
Although the code is named surveillance software failure, it applies when the signal from the angle sensor in the electric rear axle (ERAD) falls outside the permitted tolerance range. The causes are lost calibration, a wiring fault between the ERAD and the voltage converter (ISC), or an internal fault in the ISC. Electric propulsion is then not possible.
Możliwe przyczyny
- Lost calibration
- Loose contacts, contact resistance or oxidation at the connections between the ERAD and the ISC, or damaged wiring between them
- Signal cable short-circuited to ground
- Signal cable short-circuited to supply voltage or has an open circuit
- Internal fault in the voltage converter (ISC)
Co możesz zrobić
- 1Have a workshop recalibrate the angle sensor and check that the calibration passes. High voltage systems may only be handled by qualified personnel
- 2Have a workshop check the wiring between the electric rear axle and the ISC. Do not work on the wiring yourself
- 3If you have a diagnostic tool: read the angle sensor value in live data in drive mode and see whether it is steady
- 4After the repair, check that the code is not stored again
Objawy, które możesz zauważyć4
- Warning window with a warning symbol and 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
Na co może wpływać usterka2
- Electric propulsion is not possible
- Brake energy regeneration from the electric rear axle is not possible
