CAN communication timeout from the brake system
â–¶ How to fix
Check CAN connections, connectors and wiring. Also check the BMS control unit.
What you'll see
No driver-visible symptom recorded.
System reaction
The transfer box differential lock cannot be disengaged by the ABS/EBS system. The driver must release the accelerator pedal to activate the differential lock.The fault code is only generated in vehicles with BMS.
Diagnostic depth
Detection
Any of the CAN messages expected from the tachograph disappears or is missing.
Possible cause
Open circuit on CAN connection to AWD or ABS/EBS control unit. If fault codes 11070, 11080, 11100 and 11110 have been generated, there is probably an open circuit on the CAN cable to the AWD control unit.
