      • Are the resistances less than 3 ohms? 
      1. Yes:  GO to 4  on page 4.
      2. No:  REPAIR the circuit in question.
  4. CHECK FOR CORRECT Driver Seat Module (DSM) OPERATION
    1. Ignition OFF.
    2. Disconnect and inspect the Driver Seat Module (DSM) connectors.
    3. Repair:
      • corrosion (replace connector or terminals - clean module pins)
      • damaged or bent pins - replace terminals/pins
      • pushed-out pins - replace pins as necessary
    4. Reconnect the Driver Seat Module (DSM) connectors. Make sure they seat and latch correctly.
    5. Operate the system and verify the concern is still present.
      • Is the concern still present? 
      1. Yes:  CHECK On-Line Automotive Service Information System (OASIS) for any applicable Technical Service Bulletins (TSBs). If a Technical Service Bulletin (TSB) exists for this concern, discontinue this test and follow Technical Service Bulletin (TSB) instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new Driver Seat Module (DSM). REFER to DRIVER SEAT MODULE (DSM) .
      2. No:  The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
