Pinpoint Test A: The Power Seat Is Inoperative - Driver, With Power Recliner

NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition switch is on.

NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

A1 CHECK THE DRIVER SEAT CONTROL SWITCH FOR VOLTAGE
- Ignition OFF.
- Depower the SRS . Refer to Supplemental Restraint System (SRS) Depowering and Repowering .
- Disconnect: Driver Seat Side Air Bag C367.
- Disconnect: Driver Safety Belt Buckle C3065.
- Disconnect: Driver Seat Control Switch C369.
- WARNING: Make sure no one is in the vehicle and there is nothing blocking or placed in front of any airbag when the battery is connected. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.

Is the voltage greater than 11 volts?
- Yes : GO to A2 .
- No : VERIFY Battery Junction Box (BJB) fuse 23 (30A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM WIRING DIAGRAMS manual to identify possible causes of the circuit short. TEST the system for normal operation.
