Pinpoint Test A: The Power Seat Is Inoperative

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. A1 CHECK THE VOLTAGE TO THE SEAT SWITCH 
    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 air bag and/or a safety belt pretensioner (if equipped) system 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 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.
    • Key in OFF position.
    • Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of SUPPLEMENTAL RESTRAINT SYSTEM .
    • Disconnect: Driver Safety Belt Pretensioner C323.
      • 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.
    • Disconnect: Seat Regulator Control Switch C360.
    • Measure the voltage between the seat regulator control switch C360 pin 3, circuit 517 (BK/WH), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to A2.
    • No  : REPAIR circuit 517 (BK/WH). DISCONNECT the battery ground cable. CONNECT driver safety belt pretensioner C323. REPOWER the supplemental restraint system (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM . TEST the system for normal operation.
  2. A2 CHECK CIRCUIT 57 (BK) 
    • Measure the resistance between the seat regulator control switch C360 pin 1, circuit 57 (BK), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : INSTALL a new seat regulator control switch. DISCONNECT the battery ground cable. CONNECT driver safety belt pretensioner C323. REPOWER the supplemental restraint system (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM . TEST the system for normal operation.
    • No  : REPAIR circuit 57 (BK). DISCONNECT the battery ground cable. CONNECT driver safety belt pretensioner C323. REPOWER the supplemental restraint system (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM . TEST the system for normal operation.
