Test K: The Restraint Control Module (RCM) Does Not Respond To The Diagnostic Tool
PINPOINT TEST K: THE RESTRAINT CONTROL MODULE (RCM) DOES NOT RESPOND TO THE DIAGNOSTIC TOOLK1-K3:
Normal Operation
The RCM communicates with the diagnostic tool through the standard corporate protocol (SCP) communications network, circuits 914 (TN/OG) and 915 (PK/LB). Check the SCP circuits between the RCM C310a 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 circuit in the SCP network, damage to the DLC C251, or damage to the RCM C310a.
Possible Causes
- ISO 9141 circuit 70 (LB/WH) open
- RCM C310a
- RCM
