Pinpoint Test J: The Power Seat Does Not Move Horizontally/Vertically - Passenger: Overview

WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
  1. J1 CHECK THE PASSENGER SEAT MOTOR OPERATION 
    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 air bag system must be depowered. Refer to AIR BAG RESTRAINT SYSTEMS .
    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 AIR BAG RESTRAINT SYSTEMS .
    • Disconnect: Passenger Seat Side Air Bag Module C314.
    • Connect: Restraint System Diagnostic Tool 418-133 or 501-097 to Passenger Seat Side Air Bag Module C314.
    • Connect: Battery Ground Cable.
      • 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.
    • Disconnect the passenger seat motor connector in question: (forward/rearward motor C332, seat height motor C333, or seat backrest motor C338).
    • Using the following table, measure the voltage between the inoperative passenger seat motor connector, harness side and ground, while moving the seat control switch in the indicated direction:
      CONNECTOR PINS CIRCUIT REFERENCE

      Motor Connector Pin Circuit Direction of Control Switch
      Forward/Reverse Motor C332 2 32-AH44 (WH/GN) Forward
      Forward/Reverse Motor C332 1 33-AH44 Reverse (YE/GN)
      Height Motor C333 1 32-AH34 (WH/BK) Up
      Height Motor C333 2 33-AH34 (YE/BK) Down
      Backrest Motor C338 1 32-AH43 (WH/RD) Tilt Up
      Backrest Motor C338 2 33-AH43 (YE/RD) Tilt Down

    • Are the voltages greater than 10 volts in the inoperative directions? 
    1. Yes  : INSTALL a new passenger seat track or the backrest frame assembly. TEST the system for normal operation. DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from passenger seat side air bag module C314. CONNECT passenger seat side air bag module C314. REPOWER the supplemental restraint system (SRS). REFER to AIR BAG RESTRAINT SYSTEMS ..
    2. No  : GO to J2.
  2. J2 CHECK THE PASSENGER SEAT MOTOR CIRCUITS FOR A SHORT TO GROUND 
    • Disconnect: Passenger Seat Control Switch C330.
    • Using the following table, measure the resistance between passenger seat control switch C330 pins, harness side and ground:
      PINS CIRCUIT REFERENCE

      Pin Circuit Inoperative Motor
      12 32-AH43 (WH/RD) Backrest
      7 33-AH43 (YE/RD) Backrest
      4 32-AH34 (WH/BK) Height
      5 33-AH34 (YE/BK) Height
      3 32-AH44 (WH/GN) Forward/ Rearward
      11 33-AH44 (YE/GN) Forward/ Rearward

    • Are the resistances greater than 10,000 ohms? 
    1. Yes  : GO to J3.
    2. No  : REPAIR the circuit in question. TEST the system for normal operation. DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from passenger seat side air bag module C314. CONNECT passenger seat side air bag module C314. REPOWER the supplemental restraint system (SRS). REFER to AIR BAG RESTRAINT SYSTEMS .
  3. J3 CHECK FOR AN OPEN CIRCUIT 
    • Key in OFF position.
    • Measure the resistance between the passenger seat control switch C330 pins, harness side and the inoperative motor connector, harness side:
      PINS CIRCUIT REFERENCE

      C330 Pin Circuit Motor Connector
      Height Motor
      4 32-AH34 (WH/BK) C333-1
      5 33-AH34 (YE/BK) C333-2
      Forward/Reverse Motor
      3 32-AH44 (WH/GN) C332-2
      11 33-AH44 (YE/GN) C332-1
      Backrest Motor
      12 32-AH43 (WH/RD) C338-1
      7 33-AH43 (YE/RD) C338-2

    • Are all resistance readings less than 5 ohms? 
    1. Yes  : INSTALL a new passenger seat control switch. TEST the system for normal operation. DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from passenger seat side air bag module C314. CONNECT passenger seat side air bag module C314. REPOWER the supplemental restraint system (SRS). REFER to AIR BAG RESTRAINT SYSTEMS .
    2. No  : REPAIR the circuit in question. TEST the system for normal operation. DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from passenger seat side air bag module C314. CONNECT passenger seat side air bag module C314. REPOWER the supplemental restraint system (SRS).
