Circuit/System Testing

Invalid Park Signal

1. Ignition ON, shift the transaxle into Park, verify the scan tool Vehicle in Park parameter is Yes.
   • If not the specified value, test the Park/Neutral Position Park Signal circuit terminal 3 for an open/high resistance. If the circuit tests normal, replace the body control module (BCM).
2. If all circuits test normal, replace the appropriate PSDM.

Power Sliding Door Latch/Unlatch Malfunction

1. Ignition OFF, disconnect the X1 harness connector at the appropriate door contact plate.
2. Test for less than 1 ohm between the ground circuit terminal D and ground.
   • If greater than the specified range, test the ground circuit terminal D for an open/high resistance.
3. Connect a test lamp between the control circuit terminal G and ground.
4. Ignition ON, command the sliding door unlatch actuator to LATCH and UNLATCH with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
   • If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal replace the appropriate PSDM.
   • If the test lamp is always OFF, test the control circuit for a short to ground or and open/high resistance. If the circuit tests normal, replace the PSDM.
5. Ignition OFF, connect the X1 harness connector at the door contact plate. Disconnect the harness connector at sliding door unlatch actuator.
6. Test for less than 5 ohms between the ground circuit terminal A and ground.
   • If greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the door contact plate.
7. Connect a test lamp between the control circuit terminal B and ground.
8. Ignition ON, command the sliding door unlatch actuator to LATCH and UNLATCH with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
   • If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the door contact plate.
   • If the test lamp is always OFF, test the control circuit for a short to ground or and open/high resistance. If the circuit tests normal, replace the door contact plate.
9. If the circuits test normal, test or replace the sliding door unlatch actuator.

Power Sliding Door Inoperative

1. Ignition OFF, disconnect the X1 harness connector at the appropriate PSDM.
2. Test for less than 1 ohm between the ground circuit terminal 1 and ground.
   • If greater than the specified range, test the ground circuit for an open/high resistance.
3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 6 and ground.
   • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
4. Verify that a test lamp illuminates between the B+ circuit terminal 14 and ground.
   • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
5. Ignition OFF, connect the X1 harness connector and disconnect the X2 harness connector.
6. Connect a test lamp between the control terminal 1 and the control terminal 8 at the PSDM.
7. Ignition ON, command the power sliding door to OPEN and CLOSE with a scan tool. The test lamp should illuminate when commanding the OPEN and CLOSE states.
   • the test lamp remains OFF during either of the commands, replace the PSDM.
8. If all circuits test normal, test or replace the sliding door motor assembly.
