B00A0:4A
PINPOINT TEST 18: DTCs B00A0:09, 4A, 63, 64 AND 68
Normal Operation
The Restraints Control Module (RCM) is in constant communication with various control modules on the High Speed Controller Area Network (HS-CAN), one of them is the Occupant Classification System Module (OCSM). The RCM continuously monitors the HS-CAN for fault message reported by the OCS system. The RCM also checks for the correct identification of the OCSM. If the RCM detects one of the following faults reported by the OCS system, it will store DTC B00A0:09, 4A, 63, 64 or 68 in memory and send a message to the Instrument Cluster (IC) to illuminate the air bag warning indicator.
B00A0:4A-B00A0:68:
Possible Causes
- OCSM
- RCM
Diagnostic Procedure
WARNING:Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the safety canopy and cause serious personal injury or death.
WARNING:Always tighten the fasteners of the restraints control module (RCM) and impact sensor (if equipped) to the specified torque. Failure to do so may result in incorrect restraint system operation, which increases the risk of personal injury or death in a crash.
CAUTION:Use the correct probe adapter(s) when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
CAUTION:Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE:Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
NOTE:Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE:The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
