Seat Motor Control Circuit Test

  1. Ignition OFF, disconnect the X3 harness connector at the MSM.
  2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 5 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  3. Ignition OFF, connect the X3 harness connector at the MSM and disconnect the harness connector at the appropriate seat motor.
  4. Connect a test lamp between control circuit terminal 1 and control circuit terminal 2.
  5. Ignition ON, command the appropriate seat motor in the Up/Down or Forward/Rearward directions with a scan tool. The test lamp should turn ON when commanding the up and down or forward and rearward states.
    • If the test lamp remains OFF during either of the commands, test the control circuits for an open/high resistance. If the circuits test normal replace the MSM.
  6. If all circuits test normal, test or replace the seat motor.
