Normal Operation
The following modules communicate using the ISO 9141 communications network:
-
restraint control module (RCM)
-
parking aid module
-
luggage compartment lid module
The ISO 9141 network has a single-conductor data bus circuit 70 (LB/WH). The ISO 9141 communications network does not permit intermodule
communication. When the diagnostic tool communicates to modules on the ISO 9141 communications network, the diagnostic tool must request all
information or initiate module commands.
Possible Causes
-
ISO 9141 circuit 70 (LB/WH) open, short to ground, or short to voltage
