INSPECTION PROCEDURE

NOTICE:

1. When "System initializing" is displayed on the multi-display after disconnecting the cable from the negative (-) battery terminal, correct the steering angle neutral point (Click here).
   
2. 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).
   

HINT:

Images may be unclear even in normal conditions if:

1. Electrical devices are used in the cabin (noise may occur in the image).
   
2. Accessories that generate radio waves have been installed (noise may occur in the image).
   
3. The outer mirror switch assembly is operated (noise may occur in the image).
   
4. The multi-display is cold (the image immediately after turning the engine switch on (IG) may be blurred or darker than normal).
   
5. The camera lens is dirty with snow, mud, etc.
   
6. A strong beam of light, such as a sunbeam or headlight, hits the camera.
   
7. It is too dark around the camera (at night etc.).
   
8. The ambient temperature around the camera is either too high or too low.
   
9. The vehicle is tilted at a steep angle.
   
10. The rear television camera assembly lens is scratched.
    
11. The rear television camera assembly lens has drops of water on it or the humidity is high.
    
12. When the camera is used under fluorescent lights, sodium lights, or mercury lights etc., the lights and the illuminated area may appear to flicker.
    

1. Disconnect the S31 rear television camera assembly connector.
   

2. Disconnect the F77 multi-display assembly connector.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   S31-6 (CB+) - F77-39 (CA+)	Always	Below 1 Ω
   S31-3 (CV+) - F77-18 (V+)	Always	Below 1 Ω
   S31-2 (CV-) - F77-19 (V-)	Always	Below 1 Ω
   S31-5 (CGND) - F77-40 (CGND)	Always	Below 1 Ω
   S31-6 (CB+) or F77-39 (CA+) - Body ground	Always	10 kΩ or higher
   S31-3 (CV+) or F77-18 (V+) - Body ground	Always	10 kΩ or higher
   S31-2 (CV-) or F77-19 (V-) - Body ground	Always	10 kΩ or higher
   S31-5 (CGND) or F77-40 (CGND) - Body ground	Always	10 kΩ or higher

1. 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

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

   Standard Voltage:

   Tester Connection	Switch Condition	Specified Condition
   F77-39 (CA+) - F77-40 (CGND)	Engine switch on (ACC)	5.5 to 7.05 V

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

   
   
   
   
   

   Text in Illustration

   *a	Component with harness connected (Multi-media Module Receiver Assembly)	*b	Waveform 1
   *c	Waveform 2	*d	Synchronization Signal
   *e	Video Waveform	-	-

   HINT:

   A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the accessory meter assembly with the connector connected.

   Item	Content
   Terminal No. (Symbol)	F77-18 (V+) - F77-12 (GND1)
   Tool setting	200 mV/DIV., 50 μsec./DIV.
   Condition	Waveform 1: Engine starts, shift lever in R, camera lens is not covered, displaying an image. Waveform 2: Engine starts, shift lever in R, camera lens is covered, blacking out the screen.

   HINT:

   1. The video waveform changes according to the image sent by the rear television camera assembly.
      
   2. The video waveform is constantly output when the engine switch is on (ACC).
      

   OK:

   Waveform is as shown in the illustration.
   

1. Replace the multi-media module receiver assembly with a new or known good one (Click here).
   

2. Check that the parking assist monitor system operates normally.
   

   OK:

   Parking assist monitor system operates normally.
