Test C

PINPOINT TEST C: THE RESTRAINT CONTROL MODULE (RCM) DOES NOT RESPOND TO THE DIAGNOSTIC TOOL

Test C1-C3:

Normal Operation
The RCM communicates with the diagnostic tool through the International standards organization (ISO) 9141 communications network. Circuit 4-EE1 (GY/RD) receives and transmits data from the RCM to the data link connector (DLC) through in-line C214. The ability to communicate on the ISO 9141 network will be disabled if the circuit is open, shorted to ground or shorted to voltage.

Possible Causes
- circuit 4-EE1 (GY/RD) open
- RCM C310a
- RCM
