Was bedeutet der Fehlercode?

Although the code is named low voltage connector, it applies to the signals from the temperature sensor and the position sensor in the electric rear axle (ERAD). The IEM control unit sets the code when the temperature signal is missing or too low, or when the position sensor signal is wrong. Electric propulsion is then not possible.

Mögliche Ursachen

Loose contacts, contact resistance or oxidation at the joints between the ERAD and the voltage converter (ISC)
Open circuit in the signal cable
Signal cable short-circuited to ground
Damaged wiring between the ERAD and the ISC
Internal fault in the electric rear axle (ERAD)
Internal fault in the voltage converter (ISC)

Was Sie tun können

1Have a workshop check the connectors and signal wires between the electric rear axle and the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
2If you have a diagnostic tool: look at the temperature readings from the electric rear axle in live data and see whether any of them is missing or stays constantly low
3Do not carry out any work or measurements on the wiring to the electric rear axle yourself
4Have a workshop read out the fault codes after the repair and check that the code is not stored again

Symptome, die Sie bemerken können4

Drive mode PURE disengages automatically or is unavailable
