Rearview Camera Image Does Not Change When Selecting Different Views (2019)
NOTE:
- Check the vehicle 12 volt battery condition first - Refer to: 12 Volt Battery Test (Without SH-AWD) or 12 Volt Battery Test (With SH-AWD) .
- You can select three different rearview camera angles for backing up. If there is no camera image on the display, refer to: Rearview Camera Image Does Not Come On (2019) .
- Check the connectors for poor connections or loose terminals.
- Problem verification
- 1. Turn the vehicle to the ON mode, then shift the transmission to R position/mode.
If needed, start the engine, then apply the parking brake, and shift the transmission to R position.
- 2. Press the ENTER button 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 (CAMERA BIT0 line, CAMERA BIT1 line)
- 1. Shift the transmission to P position/mode.
- 2. Turn the vehicle to the OFF (LOCK) mode.
- 3. Disconnect the following connectors.
Audio-navigation unit connector G (24P) Rearview camera 8P connector (KA/KC models) Rearview camera 12P connector (KX model) - 4. Check for continuity between test points 1 and 2.

YES
Repair a short to body ground in the wire (s) between the rearview camera and the audio-navigation unit.
NO
The CAMERA BIT0 and the CAMERA BIT1 wires are not shorted to ground. Go to step 3.
- Shorted wire check (CAMERA BIT0 line to CAMERA BIT1 line)
- 1. Check for continuity between test points 1 and 2.
Is there continuity?
YES
Repair a short in the wires between the rearview camera and the audio-navigation unit.
NO
The CAMERA BIT0 and the CAMERA BIT1 wires are not shorted. Go to step 4.
- Open wire check (CAMERA BIT0 line, CAMERA BIT1 line)
- 1. Check for continuity between test points 1 and 2.
