NOTE:
- Check the vehicle 12 volt battery condition first - Refer to:
- You can select three different rearview camera angles for backing up. If there is no camera image on the display, go to: Rearview camera image does not come on or work properly troubleshooting - Refer to:
Navigation System Symptom Troubleshooting - Rearview camera image does not come on or work properly .
- 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-navigation unit to see if the rearview image changes between the wide view, the normal view, and the top down view in this order.
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 (BIT0, BIT1 lines)
-1. Shift the transmission to P position/mode or N position/mode.
- 2. Turn the vehicle to the OFF (LOCK) mode.
- 3. Disconnect the following connectors.
Audio-navigation unit connector C (24P) Rearview camera 6P connector - 4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Audio-navigation unit connector C (24P): disconnected Rearview camera 6P connector: disconnected Test circuit 1 Test point 1 Audio-navigation unit connector C (24P) No. 5 - Go to:Audio-Navigation Unit Connector For Inputs And Outputs (2016) Test point 2 Body ground Test circuit 2 Test point 1 Audio-navigation unit connector C (24P) No. 18 - Go to: Audio-Navigation Unit Connector For Inputs And Outputs (2016) Test point 2 Body ground Is there continuity?
YES
Repair a short to body ground in the wire(s) between the audio-navigation unit and the rearview camera.
NO
The BIT0 wire and BIT1 wire are not shorted. Go to step 3.
- Shorted wire check (BIT0 line to BIT1 line)
-1. Check for continuity between test points 1 and 2.

YES
Repair a short in the wires between the audio-navigation unit and the rearview camera.
NO
The BIT0 wire to BIT1 wire are not shorted. Go to step 4.
- Open wire check (BIT0, BIT1 lines)
-1. Check for continuity between test points 1 and 2.

YES
The BIT0 wire and BIT1 wire are OK. Go to step 5.
NO
Repair an open in the wire(s) between the audio-navigation unit and the rearview camera.
- Audio-navigation unit check 1 (BIT0 line)
-1. Reconnect the following connectors.
Audio-navigation unit connector C (24P) Rearview camera 6P 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 (24P) No. 5 - Go to: Audio-Navigation Unit Connector For Inputs And Outputs (2016) Test point 2 Body ground Selected view mode Voltage Wide View 0 V Normal View About 5 - 8 V Top Down View 0 V Is the voltage OK?
YES
Go to step 6.
NO
- Audio-navigation unit check 2 (BIT1 line)
-1. Measure the voltage between test points 1 and 2 as specified in the table.
