CHECK AROUND VIEW MONITOR CONTROL UNIT AND SONAR CONTROL UNIT TERMINATION CIRCUIT

  1. Remove the around view monitor control unit and the sonar control unit.

  2. Check the resistance between the around view monitor control unit terminals.

    Around view monitor control unit Resistance (Ω)
    Terminal No.
    21 5 Approx. 108 – 132

  3. Check the resistance between the sonar control unit terminals.

    Sonar control unit Resistance (Ω)
    Terminal No.
    28 26 Approx. 108 – 132

Is the measurement value within the specification?

YES>>

GO TO 7.

NO>>

Replace the around view monitor control unit and/or the sonar control unit.

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 6 circuit.

    NOTE:

    Around view monitor control unit and sonar control unit 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.
