Initial Inspection and Diagnostic Overview

1. Verify the customer concern by operating the power seat(s).
2. Visually inspect for obvious signs of mechanical and electrical damage.

Restraint system diagnostic tools MUST be installed under the seats in the side airbag and safety belt pretensioner (if equipped) to floor connectors.

NOTE:
- If a seat equipped with a seat mounted side airbag and/or a safety belt pretensioner (if equipped) system is being serviced the airbag system must be deactivated. Refer to Air Bag Systems of the appropriate car/truck service manual.
- Diagnostics or repairs are not to be performed on a side airbag system and/or a safety belt pretensioner (if equipped) system with the seats in the vehicle. Prior to attempting to diagnose/repair the side airbag system and/or a safety belt pretensioner (if equipped) system the seats must be removed from the vehicle and the restraint system diagnostic tools must be installed in the side airbag and the safety belt pretensioner (if equipped) connectors at the floor connectors. The restraint system diagnostic tools must be removed prior to operating the vehicle over the road.
- Diagnostics may be performed on seat systems other than the side airbag or the safety belt pretensioner (if equipped) system (lumbar, climate controlled, heated, power seat track) with the seat installed in the vehicle as long as the restraint system diagnostic tools are installed tinder the seats in the side airbag and safety belt pretensioner to floor connectors.
- After diagnosing/repairing a seat system, the restraint system diagnostic tools must be removed before operating the vehicle over the road.
