ACTIVE TEST
WORK SUPPORT
CORNER SEN DISTANCE SET
Corner sensor warning buzzer distance can be set to 4 phases as follows.
Test mode Function
Ecu Identification Sonar control unit part number can be read.
Self Diagnostic Result Sonar control unit checks the conditions and displays memorized error.
Data Monitor Sonar control unit input/output data in real time.
Active Test Gives a drive signal to a load to check the operation.
Work support Changes setting of each function.
Monitor Item Display Description
SONAR OPE On Around view monitor is ON. (sonar system is ON)
Off Around view monitor is OFF. (sonar system is OFF)
