For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
Anytime the Right Power Sliding Door is in a power open or close operation.

- Set Condition:
This code will set when the Right Power Sliding Door module senses the Right Power Sliding Door Clutch Driver Circuit is over 5 amps for more than 256ms.





Diagnostic Test

1. CHECK FOR DTCS
With the scan tool, record DTC's and any power sliding door inhibitors.
Erase the DTCs.
Turn the ignition off, wait 10 seconds, then turn the ignition on.
With the scan tool, read the Power Sliding Door Battery Voltage Input.

NOTE: If the Battery Voltage Input is below 12.0 volts, check the Fused B(+) and Ground circuits at the C382 or C383 Body connector and repair as necessary before proceeding.

Attempt to operate the Right Power Sliding Door
With the scan tool, read DTCs.
Does the scan tool display this DTC?

Yes

- Go To 2

No

- Using the wiring diagrams as a guide, inspect the wiring and connectors for an intermittent condition.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

2. CHECK THE RIGHT POWER SLIDING DOOR
Examine the Right Power Sliding Door for proper alignment, worn or binding rollers and hinges, loose/damaged weatherstrip, and track assembly for wear or anything that would cause an obstruction to proper operation.
Manually operate the Power Sliding Door on a known good vehicle and notice the effort needed to open and close for comparison.
Especially notice the effort needed to unlatch and close the Right Power Sliding Door.
Were there any mechanical problems found?

Yes

- Refer to Service information for the related procedure(s).
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

No

- Go To 3

3. CHECK THE RIGHT POWER SLIDING DOOR MODULE HARNESS




NOTE: At this time it will be necessary to remove the Power Sliding Door Drive Unit Assembly from the vehicle.

Turn the ignition off.
Remove the Power Sliding Door Drive Unit Assembly from the vehicle.
Disconnect the Power Sliding Door Module connector
Remove the Power Sliding Door Module from the track.
Reconnect the C382 Right Body 4 way harness connector.
Using a 12-volt test light, connect one end to the (A959) Fused B(+) circuit and the other to the (Z908/9) Ground in the PSD Module 6 way connector.

NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

Does the test tight illuminate brightly?

No

- Repair or replace the Track harness as necessary. If you have to order a new harness, be sure to specify if it is for the Driver or Passenger side of the vehicle. The Driver side has a jumper wire in the PSD Module connector for Driver Side Identification.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

Yes

- 4

4. CHECK THE DOOR MOTOR CLUTCH CIRCUIT




Reconnect the PSD Module 6 way connector to the module.
Turn the ignition on.
Connect a voltmeter between the Door Motor Clutch Driver circuit and the Door Motor Clutch Return circuit in the PSDM C2 (component side) 8 way connection.
Is the voltage between 7.5 and 8.5 volts?

Yes

- 5

No

- Replace the Power Sliding Door Module.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

5. ACTUATE THE DOOR MOTOR CLUTCH CIRCUIT




Continue to measure the voltage between the Door Motor Clutch Driver circuit and the Door Motor Clutch Return circuit in the PSDM C2 (component side) 8 way connection.
With the scan tool, actuate the Drive Clutch Engage.
Is the voltage between 12.5 and 13.8 volts when the clutch is actuated?

Yes

- Replace the Power Sliding Door Drive Unit.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

No

- Replace the Power Sliding Door Module.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.
