Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) — 2016 workshop reference 3559

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.

OPERATE CORRECTLY

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

I1 CHECK THE TEMPERATURE DOOR ACTUATOR CIRCUITS FOR A SHORT TO VOLTAGE

Ignition OFF. Disconnect In-vehicle temperature and humidity sensor C233. Disconnect Air inlet door actuator C282. Disconnect Air distribution door actuator C232. Disconnect Driver side temperature door actuator C2091. Ignition ON. Disconnect FCIM C2402A. Measure:
