- On all models, open glove box door, press glove box sides inward, and remove glove box. Through glove box opening, remove the 2 FRONT and 2 REAR passenger's air bag module bolts. Disconnect passenger's air bag connector.
- Carefully remove air bag module and place it on bench, with trim cover facing up. Attach simulator to air bag terminals on wiring harness side of passenger's air bag module connector (if equipped). Reconnect positive battery cable.
