YES>>

GO TO 6.

NO>>

Check the harness and repair or replace (if shield line is short) the root cause.

CHECK 8CH CAN GATEWAY AND ADAS CONTOL UNIT 2 TERMINATION CIRCUIT

  1. Remove the 8CH CAN gateway and the ADAS control unit 2.

  2. Check the resistance between the 8CH CAN gateway terminals.

    • With type B meter

      8CH CAN gateway Resistance (Ω)
      Terminal No.
      37 38 Approx. 108 – 132

    • With type A meter

      8CH CAN gateway Resistance (Ω)
      Terminal No.
      17 18 Approx. 108 – 132

  3. Check the resistance between the ADAS control unit 2 terminals.

    • Without ProPILOT Assist 2.1

      ADAS control unit 2 Resistance (Ω)
      Terminal No.
      27 6 Approx. 108 – 132

    • With ProPILOT Assist 2.1

      ADAS control unit 2 Resistance (Ω)
      Terminal No.
      28 29 Approx. 108 – 132

Is the measurement value within the specification?

YES>>

GO TO 7.

NO>>

Replace the 8CH CAN gateway and/or the ADAS control unit 2.

CHECK SYMPTOM

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.

Non-reproduced>>

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

CHECK UNIT REPRODUCTION

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 CAN communication 4 circuit.

    NOTE:

    8CH CAN gateway and ADAS control unit 2 have a termination circuits. 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.

Non-reproduced>>

Replace the unit whose connector was disconnected.
