Is the air temperature at the cabin temperature sensor similar to the PID?
Yes | GO to C12 | |
|---|---|---|
No | GO to Pinpoint Test N | |
C12 CHECK THE TOUCHSCREEN CONTROLS OPERATION
Using the touchscreen controls, select each climate control function. Using the touchscreen controls, select each audio control function.
Do all touchscreen controls operate?
Yes | The system is operating correctly. | |
|---|---|---|
No | Refer to the appropriate section in Group 415 for the procedure. | |
The Air Inlet Door Is Inoperative
Refer to Wiring Diagrams Cell 55 for schematic and connector information.
Normal Operation and Fault Conditions
To rotate the air inlet door actuator, the FCIM supplies voltage and ground to the air inlet door actuator through the door actuator motor circuits. To reverse the air inlet door actuator rotation, the FCIM reverses the voltage and ground circuits. The air inlet door actuator feedback resistors are supplied a ground from the FCIM by the air inlet door actuator return circuits and a 5-volt reference voltage on the air inlet door actuator reference circuits. The FCIM uses the actuator feedback resistor wiper arm position and the voltage on the air distribution door actuator feedback circuits to determine the air inlet door actuator position.
During an actuator calibration cycle, the FCIM drives the air inlet door until the door reaches both internal stops in the FCIM case. If the air inlet door is temporarily obstructed or binding during a calibration cycle, the FCIM may interpret this as the actual end of travel for the door. When this condition occurs and the FCIM commands the actuator to its end of travel, the air intake may not be from the expected source.
DTC Fault Trigger Conditions
DTC | Description | Fault Trigger Conditions |
|---|---|---|
B1083:11 | Recirculation 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. |
B1083:12 Recirculation 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. | |
B1083:13 Recirculation Damper Motor: Circuit Open | 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. |
