Pinpoint Test A: The Power Seat Is Inoperative - Driver, Without Power Recline

NOTE: If a seat equipped with a seat mounted side air bag is being serviced, the Supplemental Restraint System (SRS) must be depowered. Refer to SUPPLEMENTAL RESTRAINT SYSTEM .
NOTE: The air bag warning lamp illuminates when the Restraints Control Module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate an SRS  fault.
NOTE: The SRS  must be fully operational and free of faults before releasing the vehicle to the customer.
  1. A1 CHECK THE DRIVER SEAT CONTROL SWITCH FOR VOLTAGE 
    • Ignition OFF.
    • Depower the SRS  . Refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of SUPPLEMENTAL RESTRAINT SYSTEM .
    • Disconnect: Driver Seat Side Air Bag C328.

    • Is the resistance less than 5 ohms? 
    • Yes:  INSTALL a new seat control switch. REFER to SEAT CONTROL SWITCH - FRONT . TEST the system for normal operation.

      DISCONNECT the battery ground cable. CONNECT driver seat side air bag module C328.

      REPOWER the SRS  . REFER to SUPPLEMENTAL RESTRAINT SYSTEM .

    • No:  REPAIR the circuit. TEST the system for normal operation.
