A/C System Self-diagnosis Function: Description: Notes
The self-diagnostic system diagnoses sensors, CAN system, battery voltage, and stuck button on front air control. Refer to applicable information (items) for details. Shifting from usual control to the self-diagnostic system is accomplished by the following:
On the AV switch, hold the memory "4" button and rotate the audio "POWER/VOLUME" knob until the Self-Diagnostic screen shows on the display. Scroll down and select "Confirmation/Adjustment" with the joystick. Select "Auto Climate Control" with the joystick to start the self-test. The fan bars will flash on the display during the self-test, and then the fault codes (if any are present) will display in the ambient temperature area. Refer to "SELF-DIAGNOSIS CODE CHART ". The fault codes will continue to scroll until self-diagnostic mode is exited. To exit self-diagnostic mode, press the "BACK" button on the AV switch repeatedly until the screen displays the HVAC status.
