With Hard Diagnostic Trouble Codes (DTC)/Lamp Fault Codes (LFC)

WARNING: THE RESTRAINT SYSTEM DIAGNOSTIC TOOL IS FOR RESTRAINT SYSTEM SERVICE ONLY. REMOVE FROM VEHICLE PRIOR TO ROAD USE. FAILURE TO REMOVE COULD RESULT IN INJURY AND POSSIBLE VIOLATION OF VEHICLE SAFETY STANDARDS.

NOTE:
^ If a seat equipped with a seat mounted side airbag system is being serviced the airbag system must be deactivated per the deactivation procedure.
^ Airbag simulators (restraint system diagnostic tools) MUST be installed under the seats in the side airbag to floor connector.
^ Diagnostics or repairs are not to be performed on a side airbag system with the seat in the vehicle. Prior to attempting to diagnose/repair the side airbag system the seat must be removed from the vehicle and the restraint system diagnostic tool must be installed in side airbag connector at the floor connector. The restraint system diagnostic tool must be removed prior to operating the vehicle.
^ Diagnostics may be performed on seat systems other than the side airbag system (lumbar, climate controlled, heated, power seat track) with the seat installed in the vehicle as long as the restraint system diagnostic tool is installed under the seat in the side airbag to floor connector.
^ After diagnosing/repairing a seat system the restraint system diagnostic tool must be removed before operating the vehicle.

Most air bag Supplemental Restraint System (SRS) diagnostic procedures will require the use of the deactivation and reactivation procedure. These procedures require the removal of the driver air bag module and disconnection of the passenger and both side air bag modules, thereby removing the risk of air bag module deployment while diagnostics are being performed.

Restraint system diagnostic tools are required to perform diagnosis and testing of the SRS. The restraint system diagnostic tool is a 2-ohm resistor used to simulate air bag module connections to the system. It is not acceptable to short-circuit the air bag module connections with a zero-ohm jumper wire. If a zero-ohm jumper wire is used to short-circuit the air bag module connections, a Lamp Fault Code (LFC) will be displayed.
