Diagnosis Description
APPLICATION ITEMS
CONSULT performs the following functions via CAN communication with ADAS control unit and the communication with distance sensor.
| Diagnosis mode | Description |
|---|---|
| Work Support | It can monitor the adjustment direction indication in order to perform the radar alignment operation smoothly |
| Self Diagnostic Result | Displays malfunctioning system memorized in distance sensor |
| Data Monitor | Displays real-time input/output data of distance sensor |
| ECU Identification | Displays distance sensor part number |
| CAN Diag Support Monitor | The results of transmit/receive diagnosis of ITS communication can be read |
WORK SUPPORT
| Work support items | Description |
|---|---|
| MILLIWAVE RADAR ADJUST | Outputs millimeter waves, calculates dislocation of the millimeter waves, and indicates adjustment direction |
Radar Alignment
Refer to Work Procedure .
SELF DIAGNOSTIC RESULT
Refer to DTC Index .
NOTE:
- The details of time display are as per the following.
- 0: The malfunctions that are detected now
CAN communication system (U1000, U1010)
- 1 - 39: It increases like 0 → 1 → 2... 38 → 39 after returning to the normal condition whenever the ignition switch OFF → ON. It returns to 0 when a malfunction is detected again in the process.
- If it is over 39, it is fixed to 39 until the self-diagnosis results are erased.
Other than CAN communication system (Other than U1000, U1010)
- 1 - 49: It increases like 0 → 1 → 2... 38 → 49 after returning to the normal condition whenever the ignition switch OFF → ON. It returns to 0 when a malfunction is detected again in the process.
- If it is over 49, it is fixed to 49 until the self-diagnosis results are erased.
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.
| Monitored item [Unit] |
Description |
|---|---|
| VHCL SPEED SE [km/h] or [mph] |
Vehicle speed judged from a vehicle speed signal read by the distance sensor via ITS communication 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 distance sensor via ITS communication] |
| YAW RATE [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 communication and transmits yaw rate calculated by the ADAS control unit) Yaw rate judged from a yaw rate signal read by distance 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 distance sensor via ITS communication] |
| PWR SUP MONI [V] |
Indicates IGN voltage input by distance sensor |
| DISTANCE [m] |
Indicates the distance from the vehicle ahead |
