There are 2 functions: “Connection Confirmation”, “Adjust offset of rear view camera”.
Connection Confirmation
The input signals of steering angle sensor signal, reverse signal, and
vehicle speed signal can be checked.
Adjust Offset of Rear View Camera
If the adjustment of rear view monitor guiding line display position is
necessary when rear view camera is removed, use this mode to
adjust it.

1. CONSULT-II DIAGNOSIS
Perform CONSULT-II self-diagnosis and check the malfunction. Refer to AV- 2 4 3 , "
SELF-DIAG RESULTS" .
Is there a malfunction?
YES >> Refer to AV- 2 4 3 , "Display Item of Self-Diagnostic Results" .
NO >> GO TO 2.
2. REVERSE SIGNAL INSPECTION
1. Turn the ignition switch ON, and then select “Connection Confirmation” of “Camera Controller” on Confir-
mation/Adjustment mode.
2. Make sure that “Reverse Sensor” is turned ON when shifting the selector lever in R position.
Is it OK?
YES >> GO TO 3.
NO >> Check reverse signal circuit, and then repair the malfunctioning parts.
3. CHECK HARNESS BETWEEN CAMERA CONTROL UNIT AND REAR VIEW CAMERA
1. Turn ignition switch OFF.
2. Disconnect camera control unit connector and rear view camera connector.
3. Check continuity between camera control unit harness connec-
tor (A) B481 terminal 8 and rear view camera harness connector
(B) T109 terminal 1.
4. Check continuity between camera control unit harness connec-
tor (A) B481 terminal 8 and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4. CHECK REAR VIEW CAMERA POWER SUPPLY
1. Connect camera control unit connector and rear view camera connector.
2. Turn ignition switch ON.
3. Shift the selector lever in R position.
4. Check voltage between camera control unit harness connector
B481 terminal 8 and ground.
OK or NG
OK >> GO TO 5.
NG >> Replace camera control unit.8 – 1 : Continuity should exist.
8 – Ground : Continuity should not exist.

MAP DVD-ROM
ROUTE CALCULATION AND VISUAL GUIDANCE
The GPS indicator on the screen
remains gray.GPS signals cannot be received depending on the
vehicle location, such as in a parking garage, on a
road that has numerous tall buildings, etc.Drive on an open, straight road for a
while.
GPS signals cannot be received because objects
are placed on the instrument panel.Remove the objects from the instrument
panel.
A sufficient amount of GPS satellites are not avail-
able.Wait for the satellites to move locations
available for navigation system.
The location of vehicle icon is mis-
aligned from the actual position.When using tire chains or replacing the tires, speed
calculations based on the speed sensor may be
incorrect.Drive the vehicle for a while [at approxi-
mately 30 km/h (19 MPH) for about 30
minutes] to automatically correct the vehi-
cle icon position.
If this does not correct the vehicle icon
position, inspect AV syste.
The map data has mistake or is incomplete (the
vehicle icon position is always misaligned in the
same area).Updated road information will be included
in the next version of the map DVD-ROM. Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The message “Error” appears. Map DVD-ROM is dirty or partially damaged.Check the DVD-ROM and wipe it clean
with a soft cloth.
If there is any damage, replace the DVD-
ROM.
Symptom Possible cause Possible solution
In the auto reroute calculation,
waypoints are not included.Waypoints already passed are not included in the
auto reroute calculation.In case of going to that waypoints again,
edit the route.
Route information is not displayed.Route calculation has not yet been performed.Set the destination and perform route cal-
culation.
The vehicle is not driven on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on route guidance.
Route information is not provided for narrow streets
(roads displayed in gray).This is not a malfunction.
The auto reroute calculation (or
detour calculation) suggests the
same route as the one previously
suggested. Route calculation took priority conditions into con-
sideration, but the same route was calculated. This is not a malfunction.
A waypoint cannot be added.Five waypoints are already set on the route, includ-
ing ones that already passed.A maximum of 5 waypoints can be set on
the route. In case of going to 6 or more
waypoints, perform route calculations mul-
tiple times as necessary.
The suggested route is not dis-
played.Roads near the destination cannot be calculated.Reset the destination to a main or ordinary
road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away.Divide the way by selecting one or two
intermediate destinations, and perform
route calculations multiple times.
There are time restricted roads (by day of week, by
time) near the current vehicle location or destina-
tion.Set “Use Time Restricted Roads” to off.
A part of the route is not displayed.The suggested route includes narrow streets (roads
displayed in gray).This is not a malfunction.

clearFront glass of camera lens is dirtyDip a soft cloth into water and wipe the
glass softly.
There are raindrops, snow, etc. Wipe it with a soft cloth softly.
The sunlight or the headlight of following vehicle is
shining directly to the camera lens.It returns to the original condition if the light
applied to the lens disappears
The center position of possible
route line is not in the correct posi-
tion

Remove or replace the battery.

Replace steering angle sensor or camera control
unit.

Turn steering wheel when turning ignition switch
OFF.Perform the neutral position correction as
follows.

Fully turn the steering wheel to left/right.

Drive 100 m or more at vehicle speed 30
km/h or more. Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The remote controller does not
respond.The remote controller is not pointing at the receiver. Point the remote controller at the receiver.
The battery in the remote controller is not set cor-
rectly.Set the battery correctly.
The battery in the remote controller is discharged. Replace the battery.
The transmitter of the remote controller or the
receiver is dirty.Clean the transmitter of the remote control-
ler and the receiver.
