DIAGNOSIS SYSTEM (AV CONTROL UNIT)
Diagnosis DescriptionINFOID:0000000003765847
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-III diagnosis if the on board diagnosis does not start, e.g., the screen does not display
anything, the multifunction switch does not function. etc.
ON BOARD DIAGNOSIS
Description
 The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and
a confirmation/adjustment mode for operating manually.
 The self-diagnosis mode performs diagnoses on the AV control unit and NAVI control unit, connections
between system components as well as connections between NAVI control unit and GPS antenna and
between NAVI control unit and TEL antenna. Then it displays the diagnosis results on the display.
 The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and
set values, as well as to monitor the system error records and system communication status. The check,
modify or adjust actions generally require human intervention and judgment (the system cannot make judg-
ment automatically.

 The counter resets to 0 if an error occurs when IGN switch is turned ON. The counter increases by 1 if the
condition is normal at a next IGN ON cycle.
 The counter upper limit is 39. Any counts exceeding 39 are ignored.“ The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT-III.
Count up method B
 The counter increases by 1 if an error occurs when IGN switch is ON. The counter will not decrease even if
the condition is normal at the next IGN ON cycle.
 The counter upper limit is 50. Any counts exceeding 50 are ignored. “ The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT-III.

 CAN communication status and error counter is displayed.
 The error counter displays “OK” if any malfunction was not
detected in the past and displays “0” if a malfunction is detected. It
increases by 1 if the condition is normal at the next ignition switch
ON cycle. The upper limit of the counter is 39.
 The error counter is erased if reset.
AV COMM Diagnosis
 Displays the communication status between AV control unit (mas-
ter unit) and each unit.
 The error counter displays “OK” if any malfunction was not
detected in the past and displays “0” if a malfunction is detected. It
increases by 1 if the condition is normal at the next ignition switch
ON cycle. The upper limit of the counter is 39.
 If it resets, the error counter is erased.

Diagnosis ProcedureINFOID:0000000003765927
1.CHECK CONTINUITY DISK EJECT SIGNAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect multifunction switch connector and AV control unit connector.
3. Check continuity between multifunction switch harness connector and AV control unit harness connector.
4. Check continuity between multifunction switch harness connector and ground.
Is inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK AV CONTROL UNIT VOLTAGE
1. Connect multifunction switch connector and AV control unit connector.
2. Turn ignition switch ON.
3. Check voltage between AV control unit harness connector and ground.
Is inspection result normal?
YES >> Replace preset switch.
NO >> Replace AV control unit.
