INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the parking assist ECU after the battery terminal has been disconnected, 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/ Side Monitor System) may be needed Click here.

Tech Tips

Images can be difficult to discern even in normal conditions. For example:


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

  • Noise may occur in the image during power back door operation.

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

  • 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.

  • The ambience of 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, particular to the CCD camera.)

PROCEDURE


  1. CHECK SIDE MONITOR SYSTEM


    1. Check if the same malfunction occurs when the side monitor screen is displayed.

  2. CHECK HARNESS AND CONNECTOR (PARKING ASSIST ECU - REAR TELEVISION CAMERA ASSEMBLY AND BODY GROUND)


    1. Disconnect the F74 and F75 parking assist ECU connectors.

    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
      F75-38 (CV-) - S5-1 (CV-) Always Below 1 Ω
      F75-15 (CV+) - S5-2 (CV+) Always Below 1 Ω
      F75-14 (CB+) - S5-4 (CB+) Always Below 1 Ω
      F75-37 (CGND) - S5-3 (CGND) Always Below 1 Ω
      F74-4 (GND1) - Body ground Always Below 1 Ω
      F75-38 (CV-) - Body ground Always 10 kΩ or higher
      F75-15 (CV+) - Body ground Always 10 kΩ or higher
      F75-14 (CB+) - Body ground Always 10 kΩ or higher
      F75-37 (CGND) - Body ground Always 10 kΩ or higher

      Component with harness connected

      (Parking Assist ECU)

      Reconnect the F74 and F75 parking assist ECU connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F75-37 (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
      F75-14 (CB+) - F75-37 (CGND) Engine switch on (IG), shift lever in R 5.5 to 7.05 V

    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.
