DIAGNOSIS SYSTEM (ICC SENSOR)
CONSULT-III Function (LASER)INFOID:0000000006224280
APPLICATION ITEMS
CONSULT-III performs the following functions via CAN communication with ADAS control unit and the com-
munication with ICC sensor.
WORK SUPPORT
Laser Beam Adjust
Refer to CCS-72, "Description".
SELF DIAGNOSTIC RESULT
Refer to CCS-55, "DTC Index".
DATA MONITOR
Diagnosis mode Description
Work Support It can monitor the adjustment direction indication in order to perform the laser beam aiming operation
smoothly
Self Diagnostic Result Displays malfunctioning system memorized in ICC sensor
Data Monitor Displays real-time input/output data of ICC sensor
Ecu Identification Displays ICC sensor part number
CAN Diag Support Monitor The results of transmit/receive diagnosis of ITS communication can be read
Work support items Description
LASER BEAM ADJUST Outputs laser beam, calculates dislocation of the beam, and indicates adjustment direction
Monitored item
[Unit] Description
VHCL SPEED SE
[km/h] or [mph] Vehicle speed judged from a vehicle speed signal read by the ICC sensor via ITS communica-
tion is displayed [ADAS control unit receives a vehicle speed signal from ABS actuator and
electric unit (control unit) via CAN communication and transmits the calculated vehicle speed
to ICC sensor via ITS communication]
YAW R AT E
[deg/s] Indicates yaw rate read from ADAS control unit through ITS communication (ADAS control unit
receives yaw rate signal from ABS actuator and electric unit (control unit) via CAN communi-
cation and transmits yaw rate calculated by the ADAS control unit)
Yaw rate judged from a yaw rate signal read by ICC sensor via ITS communication is displayed
[ADAS control unit receives a yaw
rate signal from ABS actuator and electric unit (control unit)
via CAN communication and transmits the calculated yaw rate to ICC sensor via ITS commu-
nication]
PWR SUP MONI
[V] Indicates IGN voltage input by ICC sensor
