TEST
14 Disconnect the Sliding Door Control Module C2 connector.
Disconnect the Sliding Door Latch Sensing Switch connector.
Measure the resistance of the both Ground wires 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 in both ground wires at the switch connector?
Yes → Go To 15
→ Repair the Ground wire for an open.
No
15 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.
Is the resistance below 5.0 ohms?
Yes → Go To 16
→ Repair the Sliding Door Ajar Switch Sense wire for an open.
No
16 If there are no possible causes remaining, view repair.

17 Turn the ignition off.
Disconnect the Sliding Door Control Module C2 connector.
Measure the resistance between the Cinch/Release Motor Latch Driver circuit and
the Cinch/Release Motor Unlatch Driver circuit in the Sliding Door Module connec-
tor.
Wiggle the harness and check for an intermittent open condition.
Is the resistance below 2.0 ohms?
Yes → Go To 18
→ Go To 19
No
18 Turn the ignition off.
Disconnect the Sliding Door Control Module C2 connector.
Measure the resistance between ground and the Cinch/Release Motor Latch Driver
circuit.
Wiggle the harness and check for an intermittent open condition.
Is the resistance below 100.0 ohms?
Yes → Repair the Cinch/Release Motor Latch Driver circuit for a short to
→ Test Complete.
