AFUNCTION DESCRIPTION
• The Moving Object Detection (MOD) system can help alert the driver of approaching vehicles or rear objects when the driver is
backing out of a parking space.
• The MOD system comprises of the rear view camera as the main detection system, which is located on the trunk as illustrated.
• The MOD system operates at speeds below 8 km/h (5 MPH)
whenever the vehicle is in R (reverse).
• The MOD system uses the rear view camera to detect approach- ing moving objects from either side.
• The MOD system can detect moving objects on either side as close as rear obstacles of up to approximately 3 m (10 feet).
MOVING OBJECT DETECTION SY STEM OPERATION DESCRIPTION
• ITS control unit enables Moving Object Detection system.
• Combination meter turns Moving Object Detection ON indicator lamp ON/OFF according to the signals from ITS control unit via CAN communication.
• ITS control unit starts the control as follows, based on a vehicle detection signal.
Operation Condition of Moving Object Detection System
ITS control unit performs the control w hen the following conditions are satisfied:
• Moving Object Detection ON indicator: ON
• When the vehicle is moving in R (reverse) at 8 km/h (5 MPH) or less.
NOTE:
• When the Moving Object Detection system setti ng on the Vehicle Information Display is ON.
Reception unit Signal name Description
Combination
meter CAN communication Buzzer Request
Transmits a buzzer request signal when a moving object
is detected.
Display CAN communication Visual signal request Transmits a visual signal request from the ITS controller
to display Rear View while the shift selector is in R (re-
verse).

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and no-start condition.
