Diagnostic Fault Information






Circuit/System Description

The power sliding door control module (PSDM) supplies the power and ground to operate the power sliding door (PSD) motor and clutch. The direction of the motor rotation is determined by which of the control circuits is supplied 12 volts and which is grounded. The PSDM varies the current flow through the motor ground circuit to control the speed of the motor as necessary. The clutch enables the PSD to be operated manually when de-energized, or by the motor when energized.

Conditions for Running the DTC

Battery voltage must be between 9-16 volts.

Conditions for Setting the DTC

B1292 and B1293

The PSDM detects a fault in the left/right sliding door motor open control or left/right sliding door motor close control circuit.

B1292, B1293, and B1294

The PSDM detects a fault in the left/right sliding door clutch control.

B1294
* The PSDM detects an open/high resistance in the sliding door detent switch signal circuit.
* The conditions above must be present for more than 0.3 second.

Action Taken When the DTC Sets

The PSDM will attempt to activate the sliding motor assembly, but the PSD will be inoperative.

Conditions for Clearing the DTC

* The DTC will be current for as long as the fault is present.
* When the fault is no longer present, the DTC will be a history DTC.
* A history DTC will clear after 50 ignition cycles.

Diagnostic Aids

DTC B1292 may be set due to an overcinch condition in which the sliding door motor may continue to run for up to 3 seconds after the door is fully closed, refer to Sliding Rear Side Door Adjustment Sliding Rear Side Door Adjustment.

Circuit/System Verification

Ignition ON, command the appropriate power sliding door to OPEN and CLOSE with a scan tool. The power sliding door should perform the OPEN and CLOSE function.

If the power sliding door operates as commanded but is extremely difficult to open in the manual mode and sets B1293, refer to Sliding Door Clutch Malfunction.
If the power sliding door is inoperative and sets B1292, B1293 and B1294, refer to Sliding Door Clutch Malfunction.
If the power sliding door is inoperative and sets B1292 and B1293, refer to Sliding Door Cable Motor Malfunction.
If the power sliding door closes, re-opens and sets B1294, refer to Sliding Door Detent Switch Malfunction.

Circuit/System Testing

Sliding Door Clutch Malfunction
1. Ignition OFF, disconnect the X2 harness connector at the appropriate PSDM.
2. Connect a test lamp between the control terminal 7 and the ground terminal 14 at the PSDM.
3. Command the power sliding door to OPEN and CLOSE with a scan tool. The test lamp should illuminate while commanding the OPEN and CLOSE states.

• If the test lamp always OFF during the OPEN or CLOSE command, replace the PSDM.

• If the test lamp always ON, replace the PSDM.

4. If all circuits test normal, replace the sliding door motor assembly.

Sliding Door Cable Motor Malfunction
1. Ignition OFF, disconnect the X2 harness connector at the appropriate PSDM.
2. Connect a test lamp between the control terminal 1 and the control terminal 8 at the PSDM.
3. Command the power sliding door to OPEN and CLOSE with a scan tool. The test lamp should illuminate while commanding the OPEN and CLOSE states.

• If the test lamp remains OFF during either of the commands, replace the PSDM.

4. If all circuits test normal, test or replace the sliding door motor assembly

Sliding Door Detent Switch Malfunction
1. Ignition OFF, disconnect the X1 harness connector at the appropriate door contact plate.
2. Test for less than 1.0 ohm between the ground circuit terminal C and ground.

• If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify the scan tool PSD Detent Switch parameter is Inactive.

• If not the specified parameter, test the signal circuit terminal E for a short to ground. If the circuit tests normal, replace the PSDM.

4. Install a 3A fused jumper wire between the signal circuit terminal E and ground. Verify the scan tool PSD Detent Switch parameter is Active.

• If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the PSDM.

5. Ignition OFF, connect the X1 harness connector at the door contact plate. Close the door and disconnect the harness connector at sliding door detent switch.
6. Test for less than 1.0 ohm between the ground circuit terminal B 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. Ignition ON, verify the scan tool PSD Detent Switch parameter is Inactive.

• If not the specified value, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the door contact plate.

8. Install a 3A fused jumper wire between the signal circuit terminal A and ground. Verify the scan tool PSD Detent Switch parameter is Active.

• If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the door contact plate.

9. If all circuits test normal, test or replace the sliding door detent switch.

Component Testing

Clutch
1. Ignition OFF, disconnect the X2 harness connector at the appropriate PSDM.
2. Install a 15A fused jumper wire between the control terminal 7 and 12V. Momentarily install a jumper wire between the ground terminal 14 and ground. The clutch motor should engage.

• If the function does not perform as specified, replace the sliding door motor assembly.

3. Remove the jumper wires, the clutch should disengage.

• If the function does not perform as specified, replace the sliding door motor assembly.

Sliding Door Detent Switch
1. Ignition OFF, disconnect the harness connector at the appropriate sliding door detent switch.
2. Test for infinite resistance between the signal terminal A and the ground terminal B with the switch in the open position.

• If not the specified value, replace the sliding door detent switch.

3. Test for less than 1.0 ohms between the signal terminal A and the ground terminal B with the switch in the closed position.

• If greater than the specified range, replace the sliding door detent switch.

Cable Motor
1. Ignition OFF, disconnect the X2 harness connector at the appropriate PSDM.
2. Install a 15 amp fused jumper wire between the control terminal 1 and 12 volts. Momentarily install a jumper wire between the control terminal 8 and ground. The cable motor should perform the OPEN or CLOSE function.

• If the function does not perform as specified, replace the sliding door motor assembly.

3. Reverse the jumper wires; the cable motor should perform the CLOSE or OPEN function.

• If the function does not perform as specified, replace the sliding door motor assembly.
