Applies to the following models:

What does this fault code mean?
Although the code is named implausible signal, it applies when the signal from the angle sensor in the electric rear axle (ERAD) falls outside the permitted tolerance range. The fault is set while driving in gear D or R. The causes may be lost calibration, a jammed clutch in the rear axle, wiring faults, or internal faults in the ERAD or ISC. Electric propulsion is then not possible.
Possible causes
- Lost calibration
- The clutch in the electric rear axle has jammed
- Loose contacts, contact resistance or oxidation at the connections between the ERAD and the voltage converter (ISC), or damaged wiring between them
- Signal cable short-circuited to ground, to supply voltage, or with an open circuit
- Internal fault in the electric rear axle (ERAD)
- Internal fault in the voltage converter (ISC)
What you can do
- 1Have a workshop recalibrate the angle sensor and check the clutch in the electric rear axle. High voltage systems may only be handled by qualified personnel
- 2If you have a diagnostic tool: look at the angle sensor value in live data while the car is driven in gear D or R and see whether it looks implausible
- 3Do not work on the electric rear axle yourself
- 4After the repair, check that the code is not stored again
Symptoms you may notice4
- 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
What the fault can affect2
- Electric propulsion is not possible
- Brake energy regeneration from the electric rear axle is not possible
General guidance for car owners. Diagnosis on the car can point to a different cause.
