Symptom:
AMBIENT TEMPERATURE SENSOR CIRCUIT OPEN
When Monitored and Set Condition:
AMBIENT TEMPERATURE SENSOR CIRCUIT OPEN
When Monitored: Whenever the Power Liftgate Module is awake.
Set Condition: If the module senses a resistance above 382K 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
