SN-16

< SYSTEM DESCRIPTION >

[WITHOUT PARK ASSIST]

SYSTEM

• The nearest sensor from the detected obstacle applies the buzzer output frequency if plural sensors detect

any obstacle simultaneously.

NOTE:
Buzzer stops when the vehicle moves away from an obstacle and the warning level decreases.

Detection distance (default value)

Trailer Hitch Mode

The trailer hitch mode allows the setting that the sonar sensor does not accidentally detect the trailer hitch as
an obstacle when connecting a trailer hitch.

SETTINGS

• Use “Work Support” of CONSULT and enter the distance to trailer hitch. Refer to 

SN-19, "CONSULT Func-

tion"

.

• Connect trailer hitch to the vehicle and drive approximately 10 seconds or more at 5 km/h (3.1 MPH).

How To Cancel The Setting

• Disconnect trailer hitch from the vehicle. Turn the ignition switch ON and maintain this state for 10 seconds

or more.

NOTE:
*: For DTCs that parking sensor error turns ON, Refer to 

SN-28, "DTC Index"

.

SIGNAL PATH

• Sonar control unit transmits parking sensor error signal to the ON/OFF state of the combination meter via

CAN communication when detecting DTC.

• Combination meter turns ON parking sensor error when receiving parking sensor error signal.
NOTE:
*: For DTCs that parking sensor error turns ON, Refer to 

SN-28, "DTC Index"

.

WARNING OPERATING CONDITION

When all of the following conditions are satisfied:
• Ignition switch ON
• DTC is detected.

WARNING CANCEL CONDITION

When any of the following conditions is satisfied:
• The ignition switch is in a position other than ON.
• DTC is deleted.
