B0050:12
PINPOINT TEST 10: DTCs B0050: 11, 12, 13 AND 1D
Normal Operation
The Restraints Control Module (RCM) monitors the driver safety belt buckle switch (driver seatbelt sensor) circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
If a fault is detected, the RCM will store DTC B0050:11, 12, 13 or 1D in memory and send a message to the Instrument Cluster (IC) to illuminate the air bag warning indicator.
B0050:1D-B0050:13:
Possible Causes
- Wiring, terminals or connectors
- Driver safety belt buckle assembly
- 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:Never probe the electrical connectors on air bag, safety canopy or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
WARNING:Never probe the electrical connectors on safety belt buckle/retractor pretensioners or adaptive load limiting retractors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors, which increases the risk of 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.
