Rearview camera image does not change when selecting different views

WARNING: This page is about a different variant/trim than selected.

NOTE:

Check the vehicle 12 volt battery condition first .
You can select up to three different rearview camera angles when backing up. If there is no camera image on the display, go to Rearview camera image does not come on troubleshooting .
Check the connectors for poor connections or loose terminals.

Problem verification
-1. Turn the vehicle to the ON mode.

-2. Shift the transmission to R position/mode.

-3. Operate the audio unit to see if the rearview image changes between the wide view, the normal view, and the top down view.

Does the rearview camera image change properly?

YES

Intermittent failure, the system is OK at this time.

NO

The failure is duplicated, go to step 2.

Shorted wire check (CAMERA_BIT0 line, CAMERA_BIT1 line)

-1. Shift the transmission to Neutral or P position/mode.

-2. Turn the vehicle to the OFF (LOCK) mode.

-3. Disconnect the following connectors.

Audio-navigation unit connector C (32P) (with navigation)
Audio unit connector C (32P) (without navigation)

Rearview camera 8P connector

-4. Measure the resistance between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Audio-navigation unit connector C (32P) (with navigation): disconnected Audio unit connector C (32P) (without navigation): disconnected
	Rearview camera 8P connector: disconnected
Test point 1	Audio-navigation unit connector C (32P) (with navigation) No. 31
	Audio unit connector C (32P) (without navigation) No. 31
Test point 2	Body ground

Test point 1	Audio-navigation unit connector C (32P) (with navigation) No. 32
	Audio unit connector C (32P) (without navigation) No. 32
Test point 2	Body ground

Is there 1.0 MΩ or more?

YES

The CAMERA_BIT0 and the CAMERA_BIT1 wires are not shorted to ground. Go to step 3.

Repair a short to body ground in the wire(s).

Shorted wire check (CAMERA_BIT0 line to CAMERA_BIT1 line)

-1. Measure the resistance between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Audio-navigation unit connector C (32P) (with navigation): disconnected Audio unit connector C (32P) (without navigation): disconnected
	Rearview camera 8P connector: disconnected
Test point 1	Audio-navigation unit connector C (32P) (with navigation) No. 31
	Audio unit connector C (32P) (without navigation) No. 31
Test point 2	Audio-navigation unit connector C (32P) (with navigation) No. 32
	Audio unit connector C (32P) (without navigation) No. 32

Is there 1.0 MΩ or more?

YES

The CAMERA_BIT0 and the CAMERA_BIT1 wires are not shorted. Go to step 4.

Repair a short in the wires.

Open wire check (CAMERA_BIT0 line, CAMERA_BIT1 line)

-1. Measure the resistance between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Audio-navigation unit connector C (32P) (with navigation): disconnected Audio unit connector C (32P) (without navigation): disconnected
	Rearview camera 8P connector: disconnected
Test point 1	Audio-navigation unit connector C (32P) (with navigation) No. 31
	Audio unit connector C (32P) (without navigation) No. 31
Test point 2	Rearview camera 8P connector No. 3

Test point 1	Audio-navigation unit connector C (32P) (with navigation) No. 32
	Audio unit connector C (32P) (without navigation) No. 32
Test point 2	Rearview camera 8P connector No. 4

Is there 1.0 Ω or less?

YES

The CAMERA_BIT0 and the CAMERA_BIT1 wires are OK. Go to step 5.

Repair an open in the wire(s).

Voltage check (CAMERA_BIT0 line)

-1. Reconnect the following connectors.

Audio-navigation unit connector C (32P) (with navigation)
Audio unit connector C (32P) (without navigation)

Rearview camera 8P connector

-2. Turn the vehicle to the ON mode.

-3. Shift the transmission to R position/mode.

-4. Measure the voltage between test points 1 and 2 as specified in the table.

Test condition	Vehicle ON mode
Test point 1	Audio-navigation unit connector C (32P) (with navigation) No. 31
	Audio unit connector C (32P) (without navigation) No. 31
Test point 2	Body ground

Selected view mode	Voltage
Wide View	0 V
Normal View	About 5 V - 8 V
Top Down View	0 V

Is the voltage OK?

YES

Go to step 6.

NO: With navigation

Replace the audio-navigation unit .

NO: Without navigation

Replace the audio unit .

Voltage check (CAMERA_BIT1 line)

-1. Measure the voltage between test points 1 and 2 as specified in the table.

Test condition	Vehicle ON mode
Test point 1	Audio-navigation unit connector C (32P) (with navigation) No. 32
	Audio unit connector C (32P) (without navigation) No. 32
Test point 2	Body ground

Selected view mode	Voltage
Wide View	0 V
Normal View	0 V
Top Down View	About 5 V - 8 V

Is the voltage OK?

YES

Replace the rearview camera .

NO: With navigation

Replace the audio-navigation unit .

NO: Without navigation

Replace the audio unit .
