3
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 between the
License Lamp connector and the PLG C2 connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 4
No
→ Repair the Liftgate Temperature Sensor Signal circuit for an
open.
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 Ground circuit between the PLG C2 connector (cavity
20) and the License Lamp connector (cavity 8).
Is the resistance below 5.0 ohms
All
Yes
→ Go To 5
No
→ Repair the Liftgate Temperature Sensor Ground wire for an open.
Perform BODY VERIFICATION TEST - VER 1.

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
DTC PRESENT
LIFTGATE TEMPERATURE SENSOR SIGNAL CIRCUIT SHORT TO GROUND.
POWER LIFTGATE MODULE - TEMP SENSE SHORT TO GROUND
LIFTGATE TEMPERATURE SENSOR SIGNAL WIRE SHORT TO GROUND WIRE

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
