Pinpoint Test A: The Power Seat Is Inoperative

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
  1. A1 CHECK THE VOLTAGE TO THE DRIVER SEAT CONTROL SWITCH CIRCUIT 566 (DG) OR PASSENGER CIRCUIT 1462 (RD/WH) 
    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: 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 a supplemental restraint system (SRS) fault.
    NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
    • Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of SUPPLEMENTAL RESTRAINT SYSTEM article.
    • Disconnect the affected seat safety belt buckle pretensioner C3201 (driver) or C3202 (passenger).
    • Connect restraint system diagnostic tool 418-F395 to the affected seat safety belt buckle pretensioner C3201 (driver) or C3202 (passenger).
      • WARNING: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the battery ground cable is connected.
    • Connect the battery ground cable.
    • Key in OFF position.
    • Disconnect: Driver Seat Control Switch C369/Passenger Seat Control Switch C330

    • Measure the voltage between driver seat control switch C369-7, circuit 566 (DG) or passenger seat control switch C330-7, circuit 1462 (RD/WH), harness side and ground.
    • Is the voltage greater than 10 volts? 
    1. YES  : Go to  A2.
    2. NO  : VERIFY central junction box (CJB) fuse 109 (30A) (driver) or 108 (30A) (passenger) is OK. If OK, REPAIR driver circuit 566 (DG) or passenger circuit 1462 (RD/WH). TEST the system for normal operation. DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from driver seat safety belt buckle pretensioner C3201 or passenger seat safety belt buckle pretensioner C3202. CONNECT driver seat safety belt buckle pretensioner C3201 or passenger seat safety belt buckle pretensioner C3202. REPOWER the supplemental restraint system (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM article.
  2. A2 CHECK SEAT CONTROL SWITCH CIRCUIT 57 (BK) FOR AN OPEN 
    • Measure the resistance between driver seat control switch C369-1, or passenger seat control switch C330-1, circuit 57 (BK), harness side and ground.

    • Is the resistance less than 5 ohms? 
    1. YES  : INSTALL a new seat control switch. TEST the system for normal operation. DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from driver seat safety belt buckle pretensioner C3201 or passenger seat safety belt buckle pretensioner C3202. CONNECT driver seat safety belt buckle pretensioner C3201 or passenger seat safety belt buckle pretensioner C3202. REPOWER the supplemental restraint system (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM article.
    2. NO  : REPAIR circuit 57 (BK). TEST the system for normal operation. DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from driver seat safety belt buckle pretensioner C3201 or passenger seat safety belt buckle pretensioner C3202. CONNECT driver seat safety belt buckle pretensioner C3201 or passenger seat safety belt buckle pretensioner C3202. REPOWER the supplemental restraint system (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM article.
