CAN communication timeout from engine.
â–¶ How to fix

What you'll see
No driver-visible symptom recorded.
System reaction
Drive wheel disengagement can be activated even though the conditions relating to engine speed have not been met.
Diagnostic depth
Detection
Any of the CAN messages expected from the engine disappears or is missing.
Possible cause
Open circuit on CAN connection to AWD or engine control unit. If fault codes 11060, 11070, 11080 and 11100 have been generated, there is probably an open circuit on the CAN cable to the AWD control unit.
