- Set Condition:
The latch motor should perform its operation within 4 seconds. When it takes longer for the release operation, this code will set.





Diagnostic Test

1. CHECK FOR DTCS
Ensure the Right power sliding door is closed and with the scan tool, run the "Latch Home Position Test" before proceeding to ensure the latch is positioned correctly.
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.
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. BINDING POWER SLIDING DOOR
Examine the power sliding door for proper alignment, worn or binding upper and lower rollers, or a loose/damaged weatherstrip.
Examine the power sliding door 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 power sliding door.
Open the door and manually close the latch. Open and close the latch manually several times and check for any sticking conditions
Were there any mechanical problems found?

Yes
