Distribution Motor Self-Test

The motor and flap operation can be checked using the on-board distribution motor self-test function.

The self-test can be initiated by pressing and holding the ECON  and RECIRC  buttons while turning the ignition switch to the ON  position.

The control module will then compare the current motor position with the values stored in the module and will indicate an error by flashing the ECON  LED (light emitting diode).

If there are no errors, the LED will go out and the system will function normally.

To confirm that there are no errors, turn the ignition switch to the OFF  position, then back to the ON  position.

Observe the operation of the programmed defrost  LED.

If there are errors present, the programmed defrost  LED will flash and the system will attempt to calibrate itself.
