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 power liftgate several times if possible.
With the DRBIII
t, read DTCs.
Does the DRBIII
t display INCOMPLETE POWER CLOSE - VOLTAGE BELOW
MINIMUM LEVEL?
All
Yes
→ Go To 2
No
→ Using the wiring diagram/schematic as a guide, inspect the
wiring and connectors for an intermittent condition. Operate the
door several times and check for any binding conditions.
Perform BODY VERIFICATION TEST - VER 1.
2
Examine the liftgate for proper fit and alignment, or anything that would cause an
obstruction to proper operation.
Check the prop rods to ensure liftgate will fall closed from the approximately 3/4
closed position.
Does it take more effort to operate the liftgate than it should?
All
Yes
→ Refer to Service information for the related symptom(s).

before proceeding.
Turn the ignition off.
Turn all lights and accessories off.
With the DRBIII
t in 9Power Liftgate9 9Monitor Display9 9PCI Bus Info9 read the
9Battery Voltage9 and compare it to the 9PLG Bat Volts Input9.
NOTE: If the difference is greater than 0.5 volts, backprobe the Fused B(+)
at the module to verify.
Does the voltage vary more than 0.5 volts?
All
Yes
→ Using the wiring diagram/schematic as a guide, inspect the
wiring and connectors. Locate and repair the reason for the
voltage drop.

Operate the power liftgate and observe the voltage difference.
NOTE: If the difference is greater than 1.6 volts, backprobe the Fused B(+)
at the module to verify.
Does the voltage vary more than 1.6 volts when the liftgate is operating?
All
Yes
→ Using the wiring diagram/schematic as a guide, inspect the
wiring and connectors. Locate and repair the reason for the

Turn the ignition off.
Turn all lights and accessories off.
Open the Liftgate.
Remove the left rear trim panel to gain access to the Power Liftgate Module.
Remove the PLG module but leave it connected.
Backprobe voltmeter leads between the Fused B(+) and the Liftgate Close Driver
circuits in the PLG C1 connector.
Operate the power liftgate in the CLOSED position and observe the voltage
difference.
Does the voltage vary more than 1.0 volts when the liftgate is operating??
All
Yes
→ Replace the Power Liftgate Module.
Perform BODY VERIFICATION TEST - VER 1.
No

If there are no possible causes remaining, view repair.
All
Repair
Check the wiring and connections from the module to the motor
for high resistance. If the wiring is okay, replace the Power
Liftgate Drive Motor.
