How to Retrieve a DTC: Notes

The heater control panel has a self-diagnostic function. To run the self-diagnostic function, do the following:

  1. Set the mode control dial on the Vent position.
  2. Turn the ignition switch to ON (II).
  3. Within 5 seconds after turning the ignition switch on, press the recirculation control switch the required number of times depending on the recirculation indicator status:
    • If the indicator is ON, press the recirculation control switch 5 times.
    • If the indicator is OFF, press the recirculation control switch 6 times.

    The recirculation indicator will come on for 2 seconds, then blink the Diagnostic Trouble Code (DTC) to indicate a faulty component. If no DTCs are found, the indicator will not blink after the initial 2 seconds light.
