REAR VIEW CAMERA HANDLING
The rear view camera for the LDW/BSW systems is located above the rear licence plate. To keep the proper
operation of the LDW/BSW systems and prevent a system malfunction, be sure to observe the following:
• Always keep the rear view camera clean. Be careful not to damage the nozzle of automatic washer and
blower.
• Do not attach “licence plate accessory” that reflect light.
• Do not strike or damage the areas around the rear view camera.
BLIND SPOT WARNING (BSW)
• The BSW system is not a replacement for proper driving procedure and is not designed to prevent contact
with vehicles or objects. When changing lanes, always use the side and rear mirrors and turn and look in the
direction you will move to ensure it is safe to change lanes. Never rely solely on the BSW system.
• The rear view camera may not detect properly under the following conditions:
- When towing a trailer.
- When strong light enters the rear view camera. (For example, direct sunlight or headlight from the rear)
- When ambient brightness changes instantly. (For example, when the vehicle enters or exits a tunnel or
passes under a bridge.)
• Automatic washer and blower may not be able to secure detection capability when excessive dirt adheres on
the camera lens.
• The camera unit may not be able to detect when certain objects are present such as:
- Pedestrians, bicycles, animals
- Several types of vehicles such as motorcycles
- Oncoming vehicles
- A vehicle approaching rapidly from behind.
- A vehicle which your vehicle overtakes rapidly.
• The rear view camera may not be able to detect property when your vehicle travels beside the middle sec-
tion of a vehicle with long wheelbase(e.g. trailer truck, semi-trailer, tractor).
• The rear view camera detection zone is designed based on a standard lane width. When driving in a wider
lane, the camera unit may not detect vehicles in an adjacent lane. When driving in a narrow lane, the camera
unit may detect vehicles driving two lanes away.
• The rear view camera is designed to ignore most stationary objects, however objects such as guardrails,
walls, foliage and parked vehicles may occasionally be detected. This is a normal operating condition.
• The rear view camera may detect reflection image of vehicles or roadside objects that are not actually in the
detection zone, especially when the road is wet.

DIAGNOSIS SYSTEM (CAMERA CONTROL UNIT)
CONSULT Function
INFOID:0000000009723325
CONSULT FUNCTIONS
CONSULT performs the following functions via the CAN communication with the camera control unit.
ECU IDENTIFICATION
Camera control unit part number can be identified.
SELF DIAGNOSIS RESULT
• In CONSULT self-diagnosis, self-diagnosis results and error history are displayed collectively.
• The current malfunction indicates “CRNT”. The past malfunction indicates “PAST”.
• The timing is displayed as “0” if any of the error codes [U1000] and [U1010] is detected. The counter
increases by 1 if the condition is normal at the next ignition switch ON cycle.
Freeze Frame Data (FFD)
The following vehicle status is recorded when DTC is detected and is displayed on CONSULT.
DATA MONITOR
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
• Displays the status of the following vehicle signals inputted into the camera control unit.
• For each signal, actual signal can be compared with the condition recognized on the system.
Diagnosis mode
Description
ECU Identification

• The vehicle specification can be written when camera control unit is replaced.
Item name
Display content
IGN counter
(0 to 39)
Numerical value is displayed indicating the number of times that ignition switch is turned ON after the DTC
is detected.
• When “0” is displayed, it indicates that the system is presently malfunctioning.
• When any numerical number other than “0” is displayed, it indicates that system malfunction in the past is
detected, but the system is presently normal.
NOTE:
Each time when ignition switch turns OFF
→
ON, numerical number increases from 1
→
2
→
3...38
→
39.
When number of times exceeds 39, numeric display does not increase and 39 is displayed until self-diag-
nosis is erased.
