Diagnostic Procedure
1. Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG
SYSTEM.
2. Measure resistance between ground and Yellow/Black wire (circuit PR+) of air bag sensor assembly side
of passenger-side seat belt pretensioner squib harness connector. See WIRING DIAGRAMS . If
resistance is less than one megohm, repair or replace harness or connector between seat belt pretensioner
and air bag sensor assembly. If resistance is more than one megohm, go to next step.
3. Reconnect air bag sensor assembly connector C21 to air bag sensor assembly. Connect jumper wire
between Yellow/Black wire (circuit PR+) and Yellow wire (circuit PR-) of air bag sensor assembly side
of passenger-side seat belt pretensioner squib harness connector. Connect negative battery cable. Wait at
least 2 seconds. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Clear DTCs. See
CLEARING CODES under DIAGNOSIS & TESTING. Turn ignition switch to LOCK position. Wait at

DTC 62/B0133: SHORT TO BATTERY IN PASSENGER-SIDE SEAT BELT PRETENSIONER SQUIB
CIRCUIT
Description
The passenger-side seat belt pretensioner squib circuit consists of the air bag sensor assembly and passenger-
side seat belt pretensioner. The squib circuit causes the passenger-side seat belt pretensioner to deploy when
deployment conditions are satisfied.
Possible Causes
DTC 62/B0133 could be caused by a short to battery in Yellow/Black (circuit PR+) and Yellow (circuit PR-)
wires in passenger-side seat belt pretensioner squib circuit, passenger-side seat belt pretensioner squib
malfunction or air bag sensor assembly malfunction.
NOTE: During testing, if DTCs other than DTC 62/B0133 are displayed, disregard them.
