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).

Tip:

Images may be unclear even in normal conditions if:


  • Noise may occur in the image during power back door operation (w/ Power Back Door System).

  • Electrical devices are used in the cabin (noise may occur in the image).

  • Accessories that generate radio waves have been installed (noise may occur in the image).

  • The outer mirror switch assembly is operated (noise may occur in the image).

  • The camera screen is frosted over (the image immediately after turning the ignition switch to ON may be blurred or darker than normal).

  • The camera lens is dirty with snow, mud, etc.

  • A strong beam of light, such as a sunbeam or headlight, hits the camera.

  • It is too dark around the camera (at night etc.).

  • The ambient temperature around the camera is either too high or too low.

  • The vehicle is tilted at a steep angle.

  • The rear television camera assembly lens is scratched.

  • The rear television camera assembly lens has drops of water on it or the humidity is high.

  • When the camera is used under fluorescent lights, sodium lights, or mercury lights etc., the lights and the illuminated area may appear to flicker.

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


    1. Disconnect the F77 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
      F77-18 (V+) - S5-2 (CV+) Always Below 1 Ω
      F77-19 (V-) - S5-1 (CV-) Always Below 1 Ω
      F77-39 (CA+) - S5-4 (CB+) Always Below 1 Ω
      F77-40 (CGND) - S5-3 (CGND) Always Below 1 Ω
      F77-12 (GND1) - Body ground Always Below 1 Ω
      F77-18 (V+) - Body ground Always 10 kΩ or higher
      F77-19 (V-) - Body ground Always 10 kΩ or higher
      F77-39 (CA+) - Body ground Always 10 kΩ or higher
      F77-40 (CGND) - Body ground Always 10 kΩ or higher

    CHECK MULTI-MEDIA MODULE RECEIVER ASSEMBLY (CA+, CGND)


    1. A015BYQE03

      Reconnect the 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
      F77-40 (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
      F77-39 (CA+) - F77-40 (CGND) Engine switch on (IG), shift lever in R 5.5 to 7.05 V

    CHECK REAR TELEVISION CAMERA ASSEMBLY (CV+, CGND)


    1. A015C8YE02

      Reconnect the S5 rear television camera assembly connector.

      Table 2. Text in Illustration
      *a

      Component with harness connected

      		 *b Waveform A
      *c Waveform A *d Synchronization Signal
      *e Video Waveform - -

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

      Tip:

      • 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.

      Table 3. Measurement Condition
      Item Content
      Tester No. (Symbol) F77-18 (V+) - F77-40 (CGND)
      Tool Setting 0.2 V/DIV., 50 μS/DIV
      Condition

      Waveform A: Engine starts, shift lever in R (camera lens is not covered, displaying an image)

      Waveform B: Engine starts, shift lever in R (camera lens is covered, blacking out the screen)
      OK
      Waveform is as shown in the illustration.
