MULTIFUNCTION SWITCH AND PRESET SWITCH SELF-DIAGNOSIS FUNCTION
The ON/OFF operation (continuity) of each switch in the multifunction switch and preset switch can be checked.
Self-diagnosis Mode
- Press the "BACK" switch and the "UP" switch of the 8-direction switches within 10 seconds after turning the ignition switch from OFF to ACC and hold them for 3 seconds or more. Then the buzzer sounds, all indicators of the preset switch illuminate, and the self-diagnosis mode starts.
- The continuity of each switch at the ON position can be checked by pressing the switch. The buzzer sounds if the switch is normal.
Note. The hazard switch and disk eject switch cannot be checked.

Finishing Self-diagnosis Mode
Self-diagnosis mode is canceled when turning the ignition switch OFF.
MULTI AV SYSTEM ON BOARD DIAGNOSIS FUNCTION
- The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit performs a diagnosis for each unit in the system during the on board diagnosis.
- Perform a CONSULT diagnosis if the on board diagnosis does not start, e.g., the screen does not display anything, the multifunction switch does not function, etc.
- Start the self-diagnosis function and select "Self Diagnosis". Self-diagnosis subdivision screen is displayed, and the self-diagnosis mode starts. The bar graph visible on the center of the self-diagnosis subdivision screen indicates progress of the trouble diagnosis.
- Diagnosis results are displayed after the self-diagnosis is completed. The unit names and the connection lines are color-coded according to the diagnostic results.
| Diagnosis results | Unit | Connection line |
|---|---|---|
| Normal | Green | Green |
| Connection malfunction | Gray | Yellow |
| Unit malfunction Note | Red | Green |
Scheme 118
Note. Control unit (AV control unit) and is displayed in red.
- Replace AV control unit if "Self-Diagnosis did not run because of a control unit malfunction" is indicated. The symptom is AV control unit internal error. Refer to " «EXPLODED VIEW»(ref-524059-S32709120162013012500000) ".
- If multiple errors occur at the same time for a single unit, the screen switch colors are determined according to the following order of priority: red > gray. The comments of the self-diagnosis results can be viewed with a component in the diagnosis result screen.
Scheme 119
Detection Range of Self-diagnosis Mode
- The self-diagnosis mode allows the technician to diagnose the connection in the communication line between AV control unit and each unit and the internal operation of the AV control unit.
- Because the start condition of diagnosis function is a switch operation, the on board diagnosis function cannot be started up if any malfunction is detected in the communication circuit between AV control unit and multifunction switch.
