Diagnostic Test

WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FOR OTHER DTCS
1. Ignition on, engine not running.
2. With the scan tool, read HVAC DTCs.
  Is there more than one Door Control Circuit Open DTC present?
  
  Yes
  - Repair the (C34) Common Door Driver circuit for an open.
    NOTE:
    Due to the common shared driver circuit, probable area of concern is the splice, or from the splice to the A/C Heater Control harness connector. Make sure to check all inline connectors.
  No
  - Go To 2
CHECK IF DTC IS ACTIVE
1. Ignition on, engine not running.
2. With the scan tool, read HVAC DTCs.
  Is this DTC active?
  
  Yes
  - Go To 4
  No
  - Go To 3
PERFORM HVAC ACTUATOR CALIBRATION TEST
1. With the scan tool, perform the HVAC Actuator Calibration Test.
  Did this DTC change from Stored to Active while performing the HVAC Actuator Calibration Test?
  
  Yes
  - Go To 4
  No
  - Go To 7
CHECK THE RECIRCULATION DOOR ACTUATOR

1. Turn the ignition off to the lock position.
2. Disconnect the A/C Heater Control C1 harness connector.
3. Measure the resistance between the (C32) Recirculation Door Driver circuit and the (C34) Common Door Driver circuit.
  Is the resistance 38.0 Ohms (± 5.0 Ohms)?
  
  Yes
  - Replace and program the A/C Heater Control in accordance with the Service Information.
  - Perform the HVAC VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 5
CHECK THE (C32) RECIRCULATION DOOR DRIVER CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the Recirculation Door Actuator harness connector.
3. Measure the resistance of the (C32) Recirculation Door Driver circuit between the A/C Heater Control C1 harness connector and the Recirculation Door Actuator harness connector.
  Is the resistance above 1.0 Ohm?
  
  Yes
  - Repair the (C32) Recirculation Door Driver circuit for an open or high resistance.
  - Perform the HVAC VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 6
CHECK THE (C34) COMMON DOOR DRIVER CIRCUIT FOR AN OPEN

Fig 3: Measuring Resistance Of Common Door Driver Circuit
Courtesy of CHRYSLER GROUP, LLC
1. Measure the resistance of the (C34) Common Door Driver circuit between the A/C Heater Control C1 harness connector and the Recirculation Door Actuator harness connector.
  Is the resistance above 1.0 Ohm?
  
  Yes
  - Repair the (C34) Common Door Driver circuit for an open or high resistance.
    NOTE:
    Probable location is the wiring harness splice or the wiring between the splice and the door actuator.
  - Perform the HVAC VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Replace the Recirculation Door Actuator in accordance with the Service Information.
  - Perform the HVAC VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set the DTC are not present at this time.
2. Using the scan tool, check the Environmental Data to help identify the conditions in which the DTC was set.
3. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
4. Wiggle the wiring and connectors while checking for shorted and open circuits.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the HVAC VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Test complete.
