Pinpoint Test

  1. CHECK THE DSM VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
    1. Ignition OFF.
    2. Disconnect: DSM C341B.
    3. Measure:
      DSM Ground
      G08037242
      G08037243
      C341B Ground
      Pin Circuit Measurement Pin Circuit
      1 CBX03 (BU/RD)
      G08037244
      - -

    Are the voltages greater than 11 volts? 

    1. Yes: GO to .
    2. No: VERIFY the BCM fuse 7 (7.5) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the appropriate wiring diagrams to identify the possible causes of the circuit short. REFER to OEM FUSE AND RELAY INFORMATION and OEM WIRING DIAGRAMS .
  2. CHECK THE DSM GROUND CIRCUIT FOR AN OPEN
    1. Measure:
      DSM Ground
      G08037245
      G08037246
      C341B Ground
      Pin Circuit Measurement Pin Circuit
      24 GD905 (BK/GN)
      G08037247
      - -

    Are the resistances less than 3 ohms? 

    1. Yes: GO to .
    2. No: REPAIR the circuit in question.
  3. CHECK THE MS-CAN  CIRCUITS BETWEEN THE DSM AND THE MS-CAN  FOR AN OPEN
    1. Disconnect: DSM C341D.
    2. Measure:
      DSM DLC
      G08037248
      G08037249
      C341D C251
      Pin Circuit Measurement Pin Circuit
      10 VDB06 (GY/OG)
      G08037250
      3 VDB06 (GY/OG)
      9 VDB07 (VT/OG)
      G08037251
      11 VDB07 (VT/OG)

    Are the resistances less than 3 ohms? 

    1. Yes: GO to .
    2. No: REPAIR the circuit in question.
  4. CHECK FOR CORRECT DSM OPERATION
    1. Ignition OFF.
    2. Disconnect and inspect the 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 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 OASIS  for any applicable TSBs  . If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs  address this concern, INSTALL a new 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.
