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 (68É F) the resistance will be between 11.2 K and
13.5K ohms.

Symptom:
INCOMPLETE POWER CLOSE - MISSING HALL SIGNAL
When Monitored and Set Condition:
INCOMPLETE POWER CLOSE - MISSING HALL SIGNAL
When Monitored: Anytime the power liftgate is in the closing cycle.
Set Condition: If the Power Liftgate Module detects a missing hall effect signal for longer
