TEST

ACTION

APPLICABILITY

Examine the liftgate for proper alignment, worn or binding hinges, weak liftgate prop
assembly, loose/ hard weatherstrip, and track assembly for wear or anything that
would cause an obstruction to proper operation.
If necessary manually operate the liftgate of a known good vehicle and notice the
effort needed.
Compare the effort needed on the disabled vehicle.
Were there any mechanical problems found?

All

Yes

→ Refer to Service information for the related symptom(s).

Perform BODY VERIFICATION TEST - VER 1.

→ Go To 3

Turn the ignition off.
Disconnect the Power Liftgate Control Module C1 connector.
Using a 12-volt test light connected to 12-volts, check the Ground circuit.
Wiggle the harness and check for an intermittent open condition.
Does the test light illuminate brightly?

All

Yes

→ Go To 4

→ Repair the Ground circuit for an open.

Symptom:

INCOMPLETE POWER OPEN - TRANSISTOR SHORTED

When Monitored and Set Condition:

INCOMPLETE POWER OPEN - TRANSISTOR SHORTED

When Monitored:

Whenever the power liftgate is performing a power open operation.

Set Condition:

The Power Liftgate Module senses current through the transistor even

though the device is turned off. This is checked at the start of every power open cycle
during the chime period, before the liftgate starts to move.

POSSIBLE CAUSES

DTC PRESENT

POWER LIFTGATE MODULE SHORT TO GROUND

LIFTGATE OPEN DRIVER WIRE SHORT TO GROUND

LIFTGATE CLOSE DRIVER WIRE SHORT TO GROUND

POWER LIFTGATE MOTOR

TEST

ACTION

APPLICABILITY

With the DRBIII

t, record and erase DTC’s.

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

t, read ACTIVE DTCs.

Does the DRBIII

t display INCOMPLETE POWER OPEN - TRANSISTOR

SHORTED?

All

Yes

→ Go To 2

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

wiring and connectors for an intermittent condition. Operate the
liftgate several times and check for any binding conditions.
