Diagnosis Procedure - Early Production

Check the CAN diagnosis results from CONSULT to see that the following circuits have no malfunction.

• CAN communication circuit (Except for Mexico)
• CAN communication circuit 1 and CAN communication circuit 2 (For Mexico)

Are the CAN communication circuits normal?

YES

GO TO 2.

NO

Except for Mexico: Check and repair CAN communication circuit.

NO

For Mexico: Check and repair CAN communication circuit 1 and/or CAN communication circuit 2.

1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the terminals and connectors of the ADAS control unit for damage, bend and loose connection (unit side and connector side).

Is the inspection result normal?

YES

GO TO 3.

NO

Repair the terminal and connector.

1. Disconnect the following harness connectors.
   • ADAS control unit
   • ICC sensor
2. Check the continuity between the ADAS control unit harness connector and the ICC sensor harness connector.
   • For Mexico

     ADAS control unit harness connector		ICC sensor harness connector		Continuity
     Connector No.	Terminal No.	Connector No.	Terminal No.
     B104	6	E219	3	Existed
     	7		6	Existed

   • Except for Mexico

     ADAS control unit harness connector		ICC sensor harness connector		Continuity
     Connector No.	Terminal No.	Connector No.	Terminal No.
     B104	6	E202	3	Existed
     	7		6	Existed

Is the inspection result normal?

YES

GO TO 4.

NO

Repair the ADAS control unit branch line. (ITS communication circuit side).

1. Disconnect the following harness connectors.
   • Side radar RH
   • Side radar LH
   • Around view monitor control unit (With around view monitor)
   • ADAS control unit 2
   • Sonar control unit (With sonar system)
   • Accelerator pedal actuator
2. Check the continuity between the ADAS control unit harness connector terminals.

Is the inspection result normal?

YES

GO TO 5.

NO

Check the harness and repair the root cause.

Check the continuity between the ADAS control unit harness connector and the ground.

Is the inspection result normal?

YES

GO TO 6.

NO

Check the harness and repair the root cause.

1. Remove the ADAS control unit and the ICC sensor.
2. Check the resistance between the ADAS control unit terminals.

   ADAS control unit		Resistance (Ohm)
   Terminal No.
   6	7	Approx. 108 - 132

3. Check the resistance between the ICC sensor terminals.

   ICC sensor		Resistance (Ohm)
   Terminal No.
   3	6	Approx. 108 - 132

Is the inspection result normal?

YES

GO TO 7.

NO

Replace the ADAS control unit and/or the ICC sensor.

Connect all the connectors. Check if the symptoms described in the "Symptom (Results from interview with customer)" are reproduced.

Inspection result

Reproduced

GO TO 8.

NO

Start the diagnosis again. Follow the trouble diagnosis procedure when past error is detected.

Perform the reproduction test as per the following procedure for each unit.

1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Disconnect one of the unit connectors of ITS communication circuit.
   NOTE: ADAS control unit and ICC sensor have a termination circuit. Check other units first.
4. Connect the battery cable to the negative terminal. Check if the symptoms described in the "Symptom (Results from interview with customer)" are reproduced.
   NOTE: Although unit-related error symptoms occur, do not confuse them with other symptoms.

Inspection result

Reproduced

Connect the connector. Check other units as per the above procedure.

NO

Replace the unit whose connector was disconnected.
