Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the passenger window motor.
  2. Ignition OFF, test for less than 1.0 ohm of resistance between the control circuit terminal A and ground.
    • If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If circuits test normal, replace the PDM.
  3. Ignition OFF, test for less than 1.0 ohm of resistance between the control circuit terminal B and ground.
    • If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If circuits test normal, replace the PDM.
  4. Connect a test lamp between control circuit terminal A and control circuit terminal B.
  5. Ignition ON, command the passenger window UP and DOWN by pressing the passenger window switch. The test lamp should turn ON when commanding the UP and DOWN states.
    • If the test lamp remains OFF during either of the commands, test for a short to ground on either control circuit. If the circuits test normal, replace the PDM.
  6. If all circuits test normal, test or replace the passenger window motor.
