Pinpoint Test D : The Air Inlet Door Is Inoperative

WARNING: This page is about a different variant/trim than selected.
  1. Refer to Manual Climate Control System for schematic and connector information.

    Normal Operation and Fault Conditions 

    Door Actuator - Air Inlet Door, REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - System Operation and Component Description .

    During an actuator calibration cycle, the FCIM drives the air inlet mode door until the door reaches both internal stops in the HVAC case. If the air inlet mode 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 Condition
    FCIM B1083:07 Recirculation Damper Motor: Mechanical Failures Module senses the air inlet door actuator motor control is awake, no actuator drive, stall before achieving target position within 15 seconds.
    FCIM B1083:11 Recirculation Damper Motor: Circuit Short To Ground Module senses a short to ground on air inlet door actuator circuits when motor movement is commanded.
    FCIM B1083:12 Recirculation Damper Motor: Circuit Short To Battery Module senses a short to voltage on air inlet door actuator circuits when motor movement is commanded.
    FCIM B1083:13 Recirculation Damper Motor: Circuit Open Module senses an open on air inlet door actuator circuits when motor movement is commanded.
    FCIM B11F0:11 Air Intake Damper Position Sensor: Circuit Short To Ground Module senses a short to ground on air inlet door actuator circuits when motor movement is commanded.
    FCIM B11F0:15 Air Intake Damper Position Sensor: Circuit Short To Battery Or Open Module senses a short to voltage or an open on air inlet door actuator circuits when motor movement is commanded.

    Possible Sources 

    • Wiring, terminals or connectors
    • Actuator door binding, stuck or slipping
    • Air inlet mode door actuator
    • FCIM

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

    Is there any voltage present? 

    Yes  REPAIR the circuit.
    No  GO to  D2

  4. D2 CHECK THE AIR INLET DOOR ACTUATOR CIRCUITS FOR A SHORT TO GROUND

    • Ignition OFF.

    • Measure:

    Are the resistances greater than 10, 000 ohms? 

    Yes  GO to  D3
    No  REPAIR the circuit.

  5. D3 CHECK THE AIR INLET DOOR ACTUATOR CIRCUITS FOR AN OPEN

    • Disconnect Air Inlet Door Actuator C289.

    Are the resistances less than 3 ohms? 

    Yes  GO to  D4
    No  REPAIR the circuit.

  6. D4 CHECK THE AIR INLET DOOR ACTUATOR CIRCUITS FOR A SHORT TOGETHER

    • Disconnect In-vehicle temperature and humidity sensor C233.

    • Disconnect Air distribution door actuator C236.

    • Disconnect Temperature door actuator C2091.

    Are the resistances greater than 10, 000 ohms? 

    Yes  GO to  D5
    No  REPAIR the circuit.

  7. D5 CHECK FOR CORRECT ACTUATOR OPERATION

    • Ignition OFF.

    • Disconnect and inspect the air inlet door actuator connector (if not previously disconnected).

    • Repair:

      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary

    • Inspect the temperature door for binding, sticking or slipping - repair as necessary.

    • Reconnect all disconnected connectors. Connect the actuator electrical connector before the FCIM. Make sure they seat and latch correctly. WAIT 20 seconds for the range calibration to be executed after reconnecting of the module before any further assessment or measurement is made. If the actuator range calibration does not start, or has been interrupted, PERFORM the HVAC Calibration Routine, using a diagnostic scan tool.

    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  INSTALL a new air inlet door actuator. REFER to Air Inlet Door Actuator . CONNECT the actuator electrical connector before the FCIM. Make sure they seat and latch correctly. WAIT 20 seconds for the range calibration to be executed after reconnecting of the module before any further assessment or measurement is made. If the actuator range calibration does not start, or has been interrupted, PERFORM the HVAC Calibration Routine, using a diagnostic scan tool. TEST the system for normal operation. If the concern is still present, GO to  D6
    No  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
