INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the accessory meter assembly (for 12.3 Inch) or multi-display (for 8 Inch) after disconnecting the cable from the negative (-) auxiliary 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:


  • Noise may occur in the image depending on electrical devices used in the cabin.

  • Noise may occur in the image if accessories that generate radio waves have been installed.

  • The camera screen is frosted over (the image immediately after turning the power 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 ambient light surrounding the camera is too bright. (When a strong light, such as a sunbeam reflected off the vehicle body, hits the camera, the image may be blurred. This is called the "SMEAR" phenomenon, peculiar to the CCD camera.)

  • 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 NAVIGATION SYSTEM


    1. Check the operation of navigation system Click here.

      OK
      The navigation system is operated normally.

    NG

    GO TO NAVIGATION SYSTEM Click here

    OK

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


    1. Disconnect the N68 multi-media module receiver assembly connector.

    2. Disconnect the a5 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
      N68-19 (V-) - a5-2 (CV-) Always Below 1 Ω
      N68-18 (V+) - a5-3 (CV+) Always Below 1 Ω
      N68-40 (CGND) - a5-5 (CGND) Always Below 1 Ω
      N68-39 (CA+) - a5-6 (CB+) Always Below 1 Ω
      N68-12 (GND1) - Body ground Always Below 1 Ω
      a5-1 (CURT) - Body ground Always Below 1 Ω
      N68-19 (V-) - Body ground Always 10 kΩ or higher
      N68-18 (V+) - Body ground Always 10 kΩ or higher
      N68-40 (CGND) - Body ground Always 10 kΩ or higher
      N68-39 (CA+) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

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

      *a

      Component with harness connected

      (Multi-media Module Receiver Assembly)

      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
      N68-40 (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
      N68-39 (CA+) - N68-40 (CGND) Hybrid control system starts, shift lever in R 5.5 to 7.05 V

    NG

    REPLACE MULTI-MEDIA MODULE RECEIVER ASSEMBLY Click here

    OK

  4. CHECK REAR TELEVISION CAMERA ASSEMBLY (CV+, CGND)


    1. Reconnect the a5 rear television camera assembly connector.

      		 *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.

      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.

      Item Content
      Terminal No. (Symbol) N68-18 (V+) - N68-40 (CGND)
      Tool Setting 0.2 V/DIV., 50 μs/DIV.
      Condition

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

      Waveform B: Hybrid control system starts, shift lever in R (camera lens is covered, blacking out the screen)

      Tech Tips

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

      OK
      Waveform is as shown in the illustration.
