“MOD” icon, and outputs them to the display unit.
• Predictive course lines are controlled by a steering angle sensor signal received the steering angle sensor
via CAN communication.
VEHICLE INFORMATION 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.
On Board Diagnosis Function
INFOID:0000000009721848
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

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 instructionly.
• The self-diagnosis mode performs diagnoses on the AV control unit, connections between system compo-
nents as well as connections between AV control unit and GPS 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 checking,
modifying or adjusting generally require human intervention and judgment (the system cannot make judg-
ment automatically).
