ACTION

APPLICABILITY

1

Ensure vehicle is unlocked before proceeding.
Turn the ignition on.
With the DRBIII

t, record and erase DTC’s.

With the DRBIII

t, read DTC’s.

Operate the Liftgate Release several times from the Liftgate Handle Switch while
monitoring the DRBIII

t.

Does the DRBIII

t display LIFTGATE POWER RELEASE OUTPUT SHORT?

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 Body Control Module C3 connector.
Measure the resistance between ground and the Liftgate Release Driver circuit.
Is the resistance below 3.5 ohms?

All

Yes

→ Go To 3

No

→ Disconnect the BCM harness connector(s). Check connectors -

Clean/repair as necessary. If okay, replace the Body Control
Module.
Perform BODY VERIFICATION TEST - VER 1.

3

Disconnect the Liftgate Ajar Switch connector.
Disconnect the Body Control Module C3 connector.
NOTE: Check connectors - Clean/repair as necessary.
Measure the resistance between Liftgate Release Driver circuit and ground.
Is the resistance below 100.0 ohms?

All

Yes

→ Repair the Liftgate Release Driver circuit for a short to ground.

Perform BODY VERIFICATION TEST - VER 1.

No
