TEST

ACTION

APPLICABILITY

1

With the DRBIII

t, record and erase DTC’s.

Turn the ignition off, wait 10 seconds, then turn the ignition on.
Operate the liftgate several times.
With the DRBIII

t, read DTCs.

Does the DRBIII

t display PINCH SENSOR CIRCUIT OPEN?

All

Yes

→ Go To 2

No

→ Using the wiring diagram/schematic as a guide, inspect the

wiring and connectors for an intermittent condition.
Perform BODY VERIFICATION TEST - VER 1.

2

Disconnect the Power Liftgate Module C2 connector.
Measure the resistance of the Pinch Sensor Signal circuit between the Pinch Sensor
Signal and the Ground circuit (cavity 20) in the C2 connector.
Is the resistance below 22000.0 ohms?

All

No

→ Go To 3

Yes

→ Replace the Power Liftgate Module.

Perform BODY VERIFICATION TEST - VER 1.

Sensor connector and the PLG C2 connector.
Is the resistance below 20.0 ohms?

All

Yes

→ Go To 5

No

→ Repair the ground circuit for an open.

Perform BODY VERIFICATION TEST - VER 1.

5

Remove the Power Liftgate Motor trim panel.
Remove the Liftgate trim panel.
Disconnect the Power Liftgate Module C2 connector.
Disconnect the Liftgate Right Pinch Sensor connector.
Connect a jumper wire between the Right Pinch Sensor Signal circuit and the
Ground circuit in the Liftgate Right Pinch Sensor connector.
Measure the resistance of the Pinch Sensor Signal circuit between the Pinch Sensor
Signal and the Ground circuit (cav 20) in the C2 connector.
Is the resistance below 11000.0 ohms?

All

Yes

→ Replace the Right Pinch Sensor.

Perform BODY VERIFICATION TEST - VER 1.

No

→ Go To 6
