Chrysler Pacifica. Manual — part 204
Symptom:
AMBIENT TEMPERATURE SENSOR CIRCUIT SHORT TO GROUND
When Monitored and Set Condition:
AMBIENT TEMPERATURE SENSOR CIRCUIT SHORT TO GROUND
When Monitored:
Whenever the Power Liftgate Module is awake.
Set Condition:
If the module senses a resistance below 1000 ohms on the Liftgate
Temperature Sensor Signal circuit, this code will set. The normal range for the sensor is
1.2K to 382K ohms. At room temperature (68° F) the resistance will be between 11.2 K and
13.5K ohms.
POSSIBLE CAUSES

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 liftgate several times.
With the DRBIII
t, read DTCs.
Does the DRBIII
t display AMBIENT TEMPERATURE SENSOR CIRCUIT SHORT
TO GROUND?
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
Remove the power liftgate motor trim panel.
Disconnect the Power Liftgate Module C2 connector.
Measure the resistance between ground and the liftgate Temperature Sensor Signal
circuit.
Is the resistance below 5000.0 ohms?
All
Yes
→ Repair the Liftgate Temperature Sensor Signal circuit for a short
to ground.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 3

3
Remove the power liftgate motor trim panel.
Disconnect the Power Liftgate Module C2 connector.
Measure the resistance of the liftgate Temperature Sensor Signal circuit to the
Ground circuit (cavity 20) in the PLG C2 connector.
Is the resistance below 1000.0 ohms?
All
Yes
→ Go To 4
No
→ Replace the Power Liftgate Module.
Perform BODY VERIFICATION TEST - VER 1.
4
Remove the power liftgate motor trim panel.
Disconnect the Power Liftgate Module C2 connector.
Disconnect the License Lamp (light bar) connector.
Measure the resistance of the liftgate Temperature Sensor Signal circuit to the
Ground circuit (cavity 20) in the PLG C2 connector.
Is the resistance below 1000.0 ohms
All
Yes
→ Repair the Liftgate Temperature Sensor Signal wire for a short to
the Ground wire.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Replace the Liftgate Temperature Sensor (light bar).
Perform BODY VERIFICATION TEST - VER 1.

Symptom:
CONTROL MODULE FAILURE - INTERNAL FAILURE
When Monitored and Set Condition:
CONTROL MODULE FAILURE - INTERNAL FAILURE
When Monitored:
Anytime the module is awake.
Set Condition:
Whenever the module senses an internal failure (EEPROM, ROM, ADC)
this code will set. The module must be replaced.

Symptom:
INCOMPLETE LATCH CINCH - NO PAWL TRANSITION
When Monitored and Set Condition:
INCOMPLETE LATCH CINCH - NO PAWL TRANSITION
When Monitored:
Whenever the power liftgate in performing a cinching operation.
Set Condition:
The pawl switch was not detected as returning to ground during the
transition between secondary and primary cinch operation. NOTE: The liftgate may not be
fully cinched during this condition. The liftgate may cinch to primary but not be fully
seated and may pop off back to secondary.
POSSIBLE CAUSES

ACTION
APPLICABILITY
1
NOTE: This DTC will only set after the cinching operation. This may make
it difficult to reproduce.
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 LATCH CINCH - NO PAWL TRANSI-
TION?
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 or other obstruc-
tions.
Perform BODY VERIFICATION TEST - VER 1.
2
Examine the liftgate for proper fit and alignment, lose/hard or torn seals, misaligned
latch striker or anything that would cause an obstruction to proper operation.
Manually operate the liftgate of a known good vehicle and notice the effort needed to
open and close.
Compare the effort needed on the disabled 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
