Condition

The control modules transmit and receive information via a standardized serial communication method - CAN (Control Area Network). The diagnostic trouble code (DTC) is stored if the control module registers serious interference on the low speed network (CAN communication blocked).

NOTE:

In the event of system communication problems, it is not possible to communicate with the control module. Therefore it will only be possible to read off the diagnostic trouble code (DTC) if the fault is intermittent.

Substitute Value 

  • The control module shuts itself off ("bus-off").

HINT: The driver information module (DIM) will remain shut off until the power supply is broken (15, 30, X). When the power supply is connected the control module will make a new attempt to communicate. 

Possible Source 

  • Short-circuit between the control area network (CAN) wiring
  • Open-circuit in the control area network (CAN) wiring
  • Internal fault in the control module
  • Internal fault in another control module in the same part of the control area network (CAN).

Fault symptom[s] 

  • The ABS warning lamp is lit
  • The SPIN warning lamp is lit
  • The general red warning lamp is lit
  • No vehicle speed display (because there is no signal to the combined instrument panel)
  • No gauges working.
