Normal Operation

Possible Causes
A short to battery or ignition on the passenger safety belt pretensioner circuit can be caused by:
^ a short to battery or ignition on circuit 1081 (YE/RD).
^ a short to battery or ignition on circuit 1082 (YE/BK).
^ a short to battery or ignition on the passenger safety belt pretensioner.
^ an RCM internal concern.
