B0090:96
PINPOINT TEST 12: DTCs B0090:11, 81, 93 AND 96
Normal Operation
The Restraints Control Module (RCM) checks the LH front impact severity sensor (left frontal restraints sensor) and circuits for the following faults:
- Open circuit
- Short to voltage
- Short to groundIf a fault is detected, the RCM will store DTC B0090:11, 81, 93 or 96 in memory and send a message to the Instrument Cluster (IC) to illuminate the air bag warning indicator.
B0090:11-B0090:96:
Possible Causes
- Wiring, terminals or connectors
- LH front impact severity sensor (Left front restraints sensor)
- Sensor mounting
- 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.
CAUTION:Use the correct probe adapter(s) when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
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:The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE:Do not probe any impact sensor. The impact sensor can not be tested using a multi-meter.
