Image from Camera for Rear View Monitor is Abnormal [10/2022 - ]: Procedure

1. Disconnect the H108 radio and display receiver assembly connector.
2. Disconnect the W16 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
   H108-30 (CA+) - W16-6 (CB+)	Always	Below 1 Ω
   H108-28 (V+) - W16-3 (CV+)	Always	Below 1 Ω
   H108-29 (V-) - W16-2 (CV-)	Always	Below 1 Ω
   H108-27 (CGND) - W16-5 (CGND)	Always	Below 1 Ω
   H108-26 (CSLD) - Body ground	Always	Below 1 Ω
   H108-30 (CA+) or W16-6 (CB+) - Body ground	Always	10 kΩ or higher
   H108-28 (V+) or W16-3 (CV+) - Body ground	Always	10 kΩ or higher
   H108-29 (V-) or W16-2 (CV-) - Body ground	Always	10 kΩ or higher

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

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   H108-30 (CA+) - H108-27 (CGND)	Ignition switch ACC	5.5 to 7.05 V

   Result

   Proceed to
   OK
   NG

Result: 

NG 

REPLACE RADIO AND DISPLAY RECEIVER ASSEMBLY 

Refer to REMOVAL [10/2022 - 11/2023] , or refer to REMOVAL [11/2023 - ]

Result: 

OK 

See step  3

1. Reconnect the W16 rear television camera assembly connector.
2. Using an oscilloscope, check the waveform of the rear television camera assembly.

   HINT: 

   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.

   OK

   Waveform is similar to that shown in the illustration.

   Item	Content
   Measurement terminal	H108-28 (V+) - H108-29 (V-)
   Measurement setting	200 mV/DIV., 50 μs./DIV.
   Condition	Ignition switch ON, reverse (R) selected

   *a	Waveform 1 (camera lens is not covered, displaying an image)
   *b	Waveform 2 (camera lens is covered, blacking out the screen)
   *c	Synchronization Signal
   *d	Video Waveform

   HINT: 

   • The video waveform changes according to the image sent by the rear television camera assembly.
   • The video waveform is constantly output when the ignition switch is turned to ACC.
   • Make sure that the rear camera is enabled in general settings.
