INSPECTION PROCEDURE

NOTICE:

When replacing the radio and display receiver assembly, it is necessary perform the vehicle contract setting for Connected Service (Click here).

1. Disconnect the F118 radio and display receiver assembly connector.
   

2. Disconnect the S31 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
   F118-12 (V+) - S31-3 (CV+)	Always	Below 1 Ω
   F118-24 (V-) - S31-2 (CV-)	Always	Below 1 Ω
   F118-11 (CA+) - S31-6 (CB+)	Always	Below 1 Ω
   F118-23 (CGND) - S31-5 (CGND)	Always	Below 1 Ω
   F118-12 (V+) or S31-3 (CV+) - Body ground	Always	10 kΩ or higher
   F118-24 (V-) or S31-2 (CV-) - Body ground	Always	10 kΩ or higher
   F118-11 (CA+) or S31-6 (CB+) - Body ground	Always	10 kΩ or higher
   F118-23 (CGND) or S31-5 (CGND) - Body ground	Always	10 kΩ or higher

1. Remove the radio and display receiver assembly with the connector connected (Click here).
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   F118-23 (CGND) - Body ground	Always	Below 1 Ω
   F118-24 (V-) - Body ground	Always	Below 1 Ω

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

   Standard Voltage:

   Tester Connection	Switch Condition	Specified Condition
   F118-11 (CA+) - Body ground	Engine switch on (ACC)	5.5 to 7.05 V

1. Remove the radio and display receiver assembly with the connector connected (Click here).
   

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

   HINT:

   1. A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the radio and display receiver assembly with the connector connected.
      
   2. The video waveform changes according to the image sent by the rear television camera assembly.
      

   Measurement Condition

   Item	Content
   Tester No. (Symbol)	F118-12 (V+) - F118-23 (CGND)
   Tool Setting	0.2 V/DIV., 50 μS/DIV
   Condition	Waveform 1: Engine switch on (IG), shift lever in R, camera lens is not covered, displaying an image Waveform 2: Engine switch on (IG), shift lever in R, camera lens is covered, blacking out the screen

   OK:
