Chrysler Voyager. Manual — part 348
Symptom:
INCOMPLETE POWER CLOSE - HALL EFFECT SIGNAL MISSING
When Monitored and Set Condition:
INCOMPLETE POWER CLOSE - HALL EFFECT SIGNAL MISSING
When Monitored:
Whenever the power liftgate is performing a power close operation.
Set Condition:
The PLG Module detects that the motor is rotating (monitors hall effect
pulses) but no hall effect pulses are being detected. This code is set during the power close
(2 second chime period, prior to liftgate movement) operation.
POSSIBLE CAUSES
DTC PRESENT
POWER LIFTGATE MODULE - HALL EFFECT OPEN
BINDING LIFTGATE
HALL EFFECT GROUND CIRCUIT OPEN
LIFTGATE HALL EFFECT SUPPLY WIRE OPEN
LIFTGATE HALL EFFECT SUPPLY WIRE SHORT TO GROUND
LIFTGATE HALL EFFECT SUPPLY WIRE SHORT TO HARNESS GROUND

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 power liftgate several times from stop to stop if possible.
With the DRBIII
t, read ACTIVE DTCs.
Does the DRBIII
t display INCOMPLETE POWER CLOSE - HALL EFFECT
SIGNAL MISSING?
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
liftgate several times and check for any binding conditions.
Perform BODY VERIFICATION TEST - VER 1.

Examine the liftgate for proper alignment, worn or binding hinges, weak liftgate prop
assembly, loose/ hard weatherstrip, and gear teeth on the power liftgate motor
assembly for wear or anything that would cause an obstruction to proper operation.
If necessary manually operate the power liftgate on a known good vehicle and notice
the effort needed to open and close for comparison.
Especially notice the effort needed to unlatch and close the liftgate.
Does it take more effort to operate the liftgate than it should?
All
Yes
→ Refer to Service information for the related symptom(s).
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 3
3
Operate the liftgate from the full open position and put an obstacle in its path to
make it reverse.
Did the liftgate reverse back to the open position?
All
Yes
→ Go To 4
No
→ Replace the Power Liftgate Module.
Perform BODY VERIFICATION TEST - VER 1.
4
Disconnect the Power Liftgate Motor connector.
Using a 12-volt test light connected to 12-volts, check the Ground circuit.
Does the test light illuminate brightly?
All
Yes
→ Go To 5
No
→ Repair the hall effect ground circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
5
Disconnect the Power Liftgate Motor connector.
Disconnect the Power Liftgate Module C2 connector.
Measure the resistance of the Liftgate Hall Effect Supply circuit between the Power
Liftgate Motor connector and the Power Liftgate Module C2 connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 6
No
→ Repair the Liftgate Hall Effect Supply wire for an open.
Perform BODY VERIFICATION TEST - VER 1.
6
Disconnect the Power Liftgate Motor connector.
Disconnect the Power Liftgate Module C2 connector.
Measure the resistance between ground and the Liftgate Hall Effect Supply circuit.
Is the resistance below 100.0 ohms?
All
Yes
→ Repair the Liftgate Hall Effect Supply wire for a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 7
7
Disconnect the Power Liftgate Motor connector.
Disconnect the Power Liftgate Module C2 connector.
Measure the resistance between the Ground circuit (cavity 20) and the Liftgate Hall
Effect Supply circuit.
Is the resistance below 1000.0 ohms?
All
Yes
→ Repair the Liftgate Hall Effect Supply wire for a short to the
Ground circuit.
Perform BODY VERIFICATION TEST - VER 1.
