Normal Operation
The luggage compartment lid module communicates with the diagnostic tool through the international standards organization (ISO) 9141 communications network, circuit 70 (LB/WH). Check the ISO 9141 circuit between the luggage compartment lid module C4081a and the data link connector (DLC) C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open in the ISO 9141 network, damage to the DLC C251, or damage to the luggage compartment lid module C4081a.

Possible Causes
- ISO 9141 circuit 70 (LB/WH) open
