Chrysler Pacifica. Manual — part 215
Symptom:
INCOMPLETE POWER OPEN - INVALID PAWL TRANSITION
When Monitored and Set Condition:
INCOMPLETE POWER OPEN - INVALID PAWL TRANSITION
When Monitored:
During the Liftgate open cycle.
Set Condition:
The module monitors liftgate position using the optical sensor inputs. If
the module senses the pawl circuit open for over Ms. to early in the open cycle (indicating
wrong gate position), this code will set.
POSSIBLE CAUSES
DTC PRESENT
GROUND CIRCUIT OPEN
LIFTGATE PAWL SWITCH SENSE WIRE OPEN

NOTE: When this code is set, the module will abort the power open cycle and
begin
(Clutch Pulsing(. This is where the module will cycle the Liftgate
Clutch Driver until the gate stops moving (based on Optical Sensor inputs).
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 over 10 times if possible.
With the DRBIII
t, read DTCs.
Does the DRBIII
t display INCOMPLETE POWER CLOSE - INVALID PAWL
TRANSITION?
All
Yes
→ Go To 2
No
→ Using the wiring diagram/schematic as a guide, inspect the
wiring and connectors for an intermittent condition. Especially
check the C307 connector and the Liftgate Ajar circuit.
Perform BODY VERIFICATION TEST - VER 1.
2
Open the liftgate
Disconnect the Power Liftgate Module C2 connector.
Measure the resistance between the Liftgate Pawl Switch Sense circuit and the
Ground (cavity 20) circuit.
While monitoring the ohmmeter, open and close the latch several times using a
screwdriver and the Liftgate Service Release procedure.
Wiggle the harness and connectors to verify there is not an intermittent failure.
NOTE: The ohmmeter should indicate a CLOSED circuit when the latch is
OPENED and an OPEN circuit when the latch is CLOSED.
Does the ohmmeter indicate the switch is operating correctly?
All
Yes
→ Replace the Power Liftgate Module.
Perform BODY VERIFICATION TEST - VER 1.
No

NOTE: Ensure the Power Liftgate Module is connected before proceeding
with this step.
Disconnect the Liftgate Cinch/Release Motor connector.
Using a 12-volt test light connected to 12-volts, check the GROUND (cavity 1) circuit.
The test light must illuminate brightly. Compare the brightness to that of a direct
connection to the battery.
With the test light connected, move the liftgate and wiggle the harness to see if the
light flickers.
Does the test light illuminate brightly throughout the test?
All
Yes
→ Go To 4
No
→ Repair the Ground circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.

Disconnect the Liftgate Cinch/Release Motor connector.
Disconnect the Power Liftgate Module C2 connector.
Measure the resistance of the Liftgate Pawl Switch Sense wire between the Module
connector and the Motor connector.
While monitoring the ohmmeter, wiggle the harness and connectors to check for an
intermittent condition.
Is the resistance below 1.0 ohms?
All
Yes
→ Replace the Power Liftgate Cinch Release Motor Assembly-
(Latch).
Perform BODY VERIFICATION TEST - VER 1.
No
→ Repair the Liftgate Pawl Switch Sense circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.

Symptom:
INCOMPLETE POWER OPEN - LIFTGATE DRIVER CIRCUIT
SHORT TO GROUND
When Monitored and Set Condition:
INCOMPLETE POWER OPEN - LIFTGATE DRIVER CIRCUIT SHORT TO
GROUND
When Monitored:
During chime operation on opening cycle.
Set Condition:
When the module receives an opening command, it momentarily sends 12
volts to the Liftgate Open Driver circuit and then the Liftgate Close Driver circuit. If the
module senses more than a half volt drop, it will stop operations and set this code.
