INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the navigation 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 may be needed Click here.

Tech Tips

Images may be unclear even in normal conditions if:


  • 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 engine switch on (IG) 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.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - REAR TELEVISION CAMERA ASSEMBLY)


    1. Disconnect the H62 navigation receiver assembly connector.

    2. Disconnect the v2 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
      H62-7 (CA+) - v2-6 (CB+) Always Below 1 Ω
      H62-8 (V+) - v2-3 (CV+) Always Below 1 Ω
      H62-15 (CGND) - v2-5 (CGND) Always Below 1 Ω
      H62-16 (V-) - v2-2 (CV-) Always Below 1 Ω
      H62-7 (CA+) - Body ground Always 10 kΩ or higher
      H62-8 (V+) - Body ground Always 10 kΩ or higher
      H62-15 (CGND) - Body ground Always 10 kΩ or higher
      H62-16 (V-) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK NAVIGATION RECEIVER ASSEMBLY

      *a

      Component with harness connected

      (Navigation Receiver Assembly)

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      H62-15 (CGND) - Body ground Always Below 1 Ω
      H62-16 (V-) - Body ground Always Below 1 Ω

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      H62-7 (CA+) - H62-15 (CGND) Engine switch on (ACC) 5.5 to 7.05 V

    NG

    REPLACE NAVIGATION RECEIVER ASSEMBLY Click here

    OK

  3. CHECK REAR TELEVISION CAMERA ASSEMBLY


    1. Using an oscilloscope, check the waveform.

      		 *b Waveform 1
      *c Waveform 2 *d Synchronized Signal
      *e Video Waveform - -
      Measurement Condition
      Item Content
      Tester Connection H62-8 (V+) - H62-15 (CGND)
      Tool Setting 0.2 V/DIV., 50 μs/DIV.
      Condition

      • Waveform 1: Engine switch on (IG)

      • Waveform 2: Engine switch on (IG), screen blacked out by covering camera lens
      OK
      Waveform is as shown in illustration.

      Tech Tips

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