High supply voltage
â–¶ How to fix
Check all connections.Check that the cable harness for the supply voltage is connected as per the wiring diagram. Check the continuity in the cable harness with a multimeter. The voltage must be between 11.6-15.6 V. Check the voltage converter. Renew it if necessary.

Diagnostic depth
Detection
The supply voltage for the control unit is too high. The fault code is activated when the supply voltage falls below 15.6 V for more than 1 s and there is a wake-up signal.
Possible cause
