Self-Diagnosis / Function Confirmation

INTRODUCTION AND GENERAL DESCRIPTION / With & Without Navigation System
The self-diagnostic system diagnosis sensors door motors blower motor etc. by system line.

Shifting from normal control to the self-diagnostic system is accomplished by starting the engine (turning the ignition switch from OFF" to ON") and pressing [OFF] switch for at least 5 seconds.

The [OFF] switch must be pressed within 10 seconds after starting the engine (ignition switch is turned "ON").

This system will be canceled by either pressing [AUTO] switch or turning the ignition switch "OFF".

Shifting from one step to another is accomplished by means of turning temperature dial, as required. Additionally shifting from STEP 5 to AUXILIARY MECHANISM is accomplished by means of pushing [FAN] UP switch.



AUXILIARY MECHANISM: TEMPERATURE SETTING TRIMMER
The trimmer compensates for differences in range of ±3 °C (±6 °F) between temperature setting (displayed digitally) and temperature felt by driver.

- Reading and Clearing Diagnostic Trouble Codes
- Press (fan) UP switch to set system in auxiliary mode.
- Display shows "61" in auxiliary mechanism. It takes approximately 3 seconds.
- Turn temperature dial clockwise or counter clockwise. Temperature will change at a rate of 0.5 °C (1 °F) each time a switch is pressed.

When battery cable is disconnected, trimmer operation is canceled. Temperature set becomes that of initial condition, i.e. 0 °C (0 °F).
