The diagnostic trouble code (DTC) is stored if the control module detects that:

• If the control module registers a serious malfunction, e. g., that LIN-communication to Light switch module (LSM) is blocked, the diagnostic trouble code is generated.

• Ignition switch position I and II.

Substitute Value 

• None.

Possible Source 

• Short-circuit between the LIN wiring.
• Open-circuit in the LIN wiring.
• Internal fault in another unit in the same part of the LIN network.

Fault symptom[s]
