INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the multi-media module receiver 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 (w/o Side Monitor System) may be needed Click here.

PROCEDURE


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


    1. Disconnect the F76 multi-media module receiver assembly connector.

    2. Disconnect the S5 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
      F76-18 (V+) - S5-2 (CV+) Always Below 1 Ω
      F76-19 (V-) - S5-1 (CV-) Always Below 1 Ω
      F76-39 (CA+) - S5-4 (CB+) Always Below 1 Ω
      F76-40 (CGND) - S5-3 (CGND) Always Below 1 Ω
      F76-12 (GND1) - Body ground Always Below 1 Ω
      F76-18 (V+) - Body ground Always 10 kΩ or higher
      F76-19 (V-) - Body ground Always 10 kΩ or higher
      F76-39 (CA+) - Body ground Always 10 kΩ or higher
      F76-40 (CGND) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F76-40 (CGND) - 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
      F76-39 (CA+) - F76-40 (CGND) Engine switch on (IG), shift lever in R 5.5 to 7.05 V

    NG

      *e Video Waveform - -

    2. 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.

      • The video waveform changes according to the image sent by the rear television camera assembly.
