INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the multi-display assembly after disconnecting the cable from the negative (-) battery terminal, correct the steering angle neutral point Click here.

  • Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the parking assist monitor system may be needed Click here.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - REAR TELEVISION CAMERA ASSEMBLY)


    1. Disconnect the G36 multi-media module receiver assembly connector.

    2. Disconnect the Y14 rear television camera assembly connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      G36-39 (CA+) - Y14-4 (CB+) Always Below 1 Ω
      G36-18 (V+) - Y14-2 (CV+) Always Below 1 Ω
      G36-19 (V-) - Y14-1 (CV-) Always Below 1 Ω
      G36-39 (CA+) - Body ground Always 10 kΩ or higher
      G36-18 (V+) - Body ground Always 10 kΩ or higher
      G36-19 (V-) - Body ground Always 10 kΩ or higher
      G36-40 (CGND) - Body ground Always 10 kΩ or higher
      G36-18 (V+) - G36-39 (CA+) Always 10 kΩ or higher
      G36-18 (V+) - G36-19 (V-) Always 10 kΩ or higher
      G36-18 (V+) - G36-40 (CGND) Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

      Component with harness connected

      (Multi-media Module Receiver Assembly)

      Reconnect the G36 multi-media module receiver assembly connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      G36-19 (V-) - Body ground Always Below 1 Ω

    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      G36-39 (CA+) - G36-40 (CGND)

      Engine switch on (IG)

      Shift lever in R

      		 5.5 to 7.05 V

    3. Check the waveform of the rear television camera assembly using an oscilloscope.

      Tech Tips

      A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the multi-media module receiver assembly with the connector connected.

      OK
      Waveform is as shown in the illustration.
