Open the sliding door to full open position.
Using a screwdriver, click the latch to the second detent while observing the
DRB111 .
Unlatch the latch by pulling the handle switch and observe the DRB111 for a state
change.
Repeat this step several times while moving the door in different positions and
wiggling the wiring harness to check for an intermittent short.

No
4 Disconnect the Sliding Door Control Module C2 connector.
Disconnect the Sliding Door Latch Sensing Switch connector (latch assembly).
Measure the resistance of the Ground wires (both) between the PSD C2 connector
(cavity 20) and the Sliding Door Latch Sensing Switch connector.
Wiggle the harness while observing the ohmmeter.
Is the resistance below 5.0 ohms on both ground wires?
Yes → Go To 5
→ Repair the Ground wire for an open.
No
5 Disconnect the Sliding Door Control Module C2 connector.
Disconnect the Sliding Door Latch Sensing Switch connector (latch assembly).
Measure the resistance of the Sliding Door Ajar Switch Sense wire between the PSD
C2 connector and the Sliding Door Latch Sensing Switch connector.
