Author: ERC Page: 98 of 301 Fault Detection Condition Temperature Door Control Motor Feedback Line - Circuit short to Ground Normal Operating Condition With the Temperature feedback line connected to the harness and with Ignition ON, checks the voltage between blue connector pin no 10& ground of the Connector. The voltage range should be in between 1.3 to 3.89 V Probable Trouble Area 1) Motor connector is not connected firmly (open) 2) Motor feedback line short to Ground Healing Condition NA Component Details: The actuator controls the position of the Co-Driver temperature blend door based on the voltage signal from the FATC module. Potentiometer, inside the actuator, sends a feedback signal to the controller and controller cuts off the voltage signal coming from the controller when the required door position is achieved. Preliminary Checks: Switch On the IGN & perform the following check. 3) Connect the Diagnostics tool & check the DTC fault code 4) Read ECU parameter value Target Position of Co-Driver Temperature Door Flap and Co-Driver Temperature Door flap Position (Internal Value) for actual and target position of Actuator Trouble Shooting:-
