REAR VIEW MONITOR SYSTEM (w/ Navigation System)

Disconnect the D22 navigation receiver assembly connector.

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

Terminal No. (Symbol)	Wiring Color	Terminal Description	Condition	Specified Condition
D22-7 (GND) - Body ground	BR - Body ground	Ground	Always	Below 1 Ω
D22-4 (B) - D22-7 (GND)	SB - BR	Battery	Always	11 to 14 V

If the result is not as specified, there may be a malfunction on the wire harness side.

Reconnect the D22 navigation receiver assembly connector.

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

Terminal No. (Symbol)	Wiring Color	Terminal Description	Condition	Specified Condition
D24-2 (CA+) - D24-12 (CGND)	B - Shielded	Power source	Ignition switch ON, shift lever in R	5.5 to 7.05 V
D24-12 (CGND) - Body ground	Shielded - Body ground	Shielding	Always	Below 1 V
D25-5 (REV) - D22-7 (GND)	R - BR	Reverse signal	Ignition switch ON, shift lever in R	11 to 14 V
D25-5 (REV) - D22-7 (GND)	R - BR	Reverse signal	Ignition switch ON, shift lever not in R	Below 1 V
D24-1 (V+) - D24-11 (V-)	R - W	Display signal	Ignition switch ON, shift lever in R	Waveform 1
D24-1 (V+) - D24-11 (V-)	R - W	Display signal	Ignition switch ON, shift lever in R, screen blacked out by covering camera lens	Waveform 2

If the result is not as specified, the navigation receiver assembly may have a malfunction.

Using an oscilloscope, check waveform 1.
