1. Disconnect and isolate the battery negative cable.
WARNING: Wait two minutes for the airbag system
reserve capacitor to discharge before beginning
any airbag system or component service. Failure
to do so may result in accidental airbag deploy-
ment, personal injury or death.
2. Reach under the front edge of the passenger front
seat cushion to access and disconnect the two har-
ness connectors (3) from the Occupant Classifica-
tion Module (OCM) (4).
3. Remove the two screws (2) that secure the OCM
to the OCM bracket (1).
4. Remove the OCM from under the passenger front
seat.
INSTALLATION
WARNING: Never replace both the Occupant Restraint Controller (ORC) and the Occupant Classification
Module (OCM) at the same time. If both require replacement, replace one, then perform the Airbag System
test (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TESTING - AIRBAG SYSTEM) before replac-
ing the other. Both the ORC and the OCM store Occupant Classification System (OCS) calibration data,
which they transfer to one another when one of them is replaced. If both are replaced at the same time, an
irreversible fault will be set in both modules and the OCS may malfunction and result in personal injury or
death.
1. Carefully position the Occupant Classification Mod-
ule (OCM) (4) to the OCM bracket (1).
2. Install and tighten the two screws (2) that secure
the OCM to the OCM bracket. Tighten the screws
to 2 N·m (20 in. lbs.).
3. Connect the two harness connectors (3) to the
OCM.
WARNING: Do not connect the battery negative
cable (Refer to 8 - ELECTRICAL/RESTRAINTS -
DIAGNOSIS AND TESTING - AIRBAG SYSTEM).
Personal injury or death may result if the system
test is not performed first.
WARNING: Following successful completion of the
Airbag System test procedure, the Occupant Clas-
sification System Verification Test must be done
using a scan tool and the appropriate diagnostic
information.
