The Temperature Control Is Inoperative Or Does Not Operate Correctly - Driver Side
Refer to Wiring Diagrams Cell 55 for schematic and connector information.
Normal Operation and Fault Conditions
Temperature Door Actuator - Driver side, REFER to: Climate Control System - Vehicles With: Dual Automatic Temperature Control (DATC) - System Operation and Component Description (412-00 Climate Control System - General Information, Description and Operation).
During an actuator calibration cycle, the FCIM drives the temperature door until the door reaches both internal stops in the HVAC case. If the temperature door is temporarily obstructed or binding during a calibration cycle, the module may interpret this as the actual end of travel for the door. When this condition occurs and the module commands the actuator to its end of travel, the airflow may not be the expected temperature.
DTC Fault Trigger Conditions
DTC | Description | Fault Trigger Conditions |
|---|---|---|
B1081:11 | Left Temperature Damper Motor: Circuit Short To Ground | This DTC sets when the module senses lower than expected voltage on an actuator motor circuit when voltage is applied to drive the motor, indicating a short to ground. The motor can move only in one direction. |
B1081:12 Left Temperature Damper Motor: Circuit Short To Battery | This DTC sets when the module senses higher than expected voltage on the actuator motor circuit when ground is applied to drive the motor, indicating a short to voltage. The motor can move only in one direction. | |
B1081:13 Left Temperature Damper Motor: Open Circuit | This DTC sets when the module senses no voltage on the actuator motor circuit when ground is applied to drive the motor, indicating an open circuit. The motor cannot move. | |
B11E5:12 Left HVAC Damper Position Sensor: Circuit Short to Battery | This DTC sets when the module senses greater than 5 volts on the actuator feedback circuit, indicating a short to voltage. | |
B11E5:14 Left HVAC Damper Position Sensor: Circuit Short to Ground or Open | This DTC sets when the module senses less than 1 volt on the actuator feedback circuit, indicating an open circuit or a short to ground. |
