PINPOINT TEST H: LFC 34/DTC B1882 - PASSENGER PRETENSIONER CIRCUIT SHORT TO VOLTAGE

Test H1-H2:

Test H2-H3:

Test H4-H5:

Normal Operation

NOTE: There is no restraint system diagnostic tool for the safety belt buckle pretensioners. If the ignition switch is set to RUN or START with the safety belt buckle pretensioner electrical connector(s) disconnected, the DTC for an open circuit will be activated.

The safety belt pretensioners are activated by the RCM to remove excessive slack from the safety belt webbing when an impact exceeding preprogrammed limits is detected.

The restraints control module (RCM) monitors the circuits to the passenger belt pretensioner for faults. If the RCM detects an unexpected voltage on the passenger safety belt pretensioner circuits, it will store diagnostic trouble code (DTC) B1882 in memory and flash lamp fault code (LFC) 34 (or higher priority code if one exists) on the air bag indicator.

Fault Conditions
The RCM monitors for the following fault conditions:
- circuit short to voltage.

Possible Causes
A safety belt pretensioner fault can be caused by:
- faulted wiring, terminals, or connectors.
- a faulted RCM.
