Reading and Clearing Diagnostic Trouble Codes

The climate control unit has a self-diagnosis function.

Self-diagnosis Function:

Running the Self-diagnosis Function
Turn the ignition switch ON (II), then press both the AUTO and OFF buttons at the same time. While the buttons are pressed, indicator lights A, B, C, D, E and F respectively will come on to indicate a faulty component.

NOTE: In case of multiple problems, the respective indicator lights will come on. If indicator lights A, B, C, D, and E come on at the same time, there may be an open in the common ground wire of the sensors.

Resetting the Self-diagnosis Function
Turning the ignition switch OFF will cancel the self-diagnosis function. After service work, run the self-diagnosis function once again to check that there is no other problem.
