Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the memory seat adjuster switch.
  2. Ignition ON, verify that a test lamp illuminates between the reference voltage circuit terminal 2 and ground.
    • If the test lamp does not illuminate, test the reference voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the driver door lock/window switch.
  3. Test for less than 1 V between the signal circuit terminal 1 and ground.
    • If greater than a specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the driver door lock/window switch.
  4. Ignition OFF, connect the harness connector at the memory seat adjuster switch.
  5. Ignition ON, verify the scan tool Driver Door Switch Memory Recall Switches parameter is approximately 2.75 V while pressing the memory 1 switch.
    • If not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, test or replace the memory seat adjuster switch.
  6. Verify the scan tool Memory Recall Switches parameter is approximately 1.75 V while pressing the memory 2 switch.
    • If not the specified value, test or replace the memory seat adjuster switch.
  7. Verify the scan tool Memory Recall Switches parameter is approximately 1.0 V while pressing the EXIT switch.
    • If not the specified value, test or replace the memory seat adjuster switch.
  8. If all circuits test normal, replace the MSM.
