Navigation System Symptom Troubleshooting - Rearview camera image does not come on or work properly (2016-17)

Rearview camera image does not come on or work properly 

1. Problem verification:

   Press the engine start/stop button to select the ON mode.

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

   Does the center display unit image change when the transmission is shifted to R position/mode?

   YES 

   Intermittent failure, the system is OK at this time.

   NO 

   The failure is duplicated, go to step 2.

2. System Diagnostic Mode check:

   Shift the transmission to P position/mode.

   - 2. Go into the System Diagnostic Mode, and use the System Links to check the Rear Camera icon status .

   Is the Rear Camera icon green?

   YES 

   Go to step 3.

   NO 

   Go to navigation DTC 2608 (R-Camera Diag) troubleshooting .

3. Determine possible failure area (BACK LT line, others):

   Go into the System Diagnostic Mode, and use the Car Status diagnosis to check the BACK signal .

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

   Does the BACK signal change from [0] to [1] when the transmission is shifted from P position/mode to R position/mode?

   YES 

   Go to step 5.

   NO 

   Go to step 4.

4. Open wire check (BACK LT line):

   Shift the transmission to P position/mode.

   - 2. Press the engine start/stop button to select the OFF mode.

   - 3. Disconnect the following connector.

   Audio-navigation unit connector G (24P)

   - 4. Press the engine start/stop button to select the ON mode.

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

   - 6. Measure the voltage between test points 1 and 2.

   Test condition	ON mode
   	Audio-navigation unit connector G (24P): disconnected
   Test circuit	BACK LT
   Test point 1	Audio-navigation unit connector G (24P) No. 24 (GRY)
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   Replace the audio-navigation unit .

   NO 

   Repair an open in the wire between the audio-navigation unit and the under-dash fuse/relay box.

5. Shorted wire check (CAMERA lines) 1:

   Shift the transmission to P position/mode.

   - 2. Press the engine start/stop button to select the OFF mode.

   - 3. Disconnect the following connector.

   Rearview camera 8P connector

   Audio-navigation unit connector G (24P)

   - 4. Check for continuity between these test points and body ground individually.

   Test condition	OFF mode
   	Rearview camera 8P connector: disconnected
   	Audio-navigation unit connector G (24P): disconnected

   Connector	Test circuit	Terminal
   Audio-navigation unit connector G (24P)	CAMERA GND	No. 3 (RED)
   	CAMERA GND	No. 4 (GRN)
   	CAMERA V	No. 15 (WHT)
   	CAMERA VCC	No. 16 (BLK)

   Is there continuity?

   YES 

   There is a short to body ground in the wire(s) between the audio-navigation unit and the rearview camera. Replace the affected shielded harness.

   NO 

   The CAMERA wires are OK. Go to step 6.

6. Shorted wire check (CAMERA lines) 2:

   Check for continuity between test points 1 and 2.

   Test condition	OFF mode
   	Rearview camera 8P connector: disconnected
   	Audio-navigation unit connector G (24P): disconnected

   Test circuits	Connector: Audio-navigation unit connector G (24P)
   	Test point 1	Test points 2
   SH CAMERA to CAMERA GND, CAMERA GND, CAMERA V, CAMERA VCC	No. 2 (GRY)	No. 3 (RED), No. 4 (GRN), No. 15 (WHT), No. 16 (BLK)
   CAMERA GND to CAMERA GND, CAMERA V, CAMERA VCC	No. 3 (RED)	No. 4 (GRN), No. 15 (WHT), No. 16 (BLK)
   CAMERA GND to CAMERA V, CAMERA VCC	No. 4 (GRN)	No. 15 (WHT), No. 16 (BLK)
   CAMERA V to CAMERA VCC	No. 15 (WHT)	No. 16 (BLK)

   Is there continuity between any of the terminals?

   YES 

   There is a short in the wires between the audio-navigation unit and the rearview camera. Replace the affected shielded harness.

   NO 

   The CAMERA wires are not shorted in the wires. Go to step 7.

7. Open wire check (CAMERA lines):

   Check for continuity between test points 1 and 2.

   Test condition	OFF mode
   	Rearview camera 8P connector: disconnected
   	Audio-navigation unit connector G (24P): disconnected

   Test circuit	Test point 1:Audio-navigation unit connector G (24P)	Test point 2:Rearview camera 8P connector
   CAMERA GND	No. 3 (RED)	No. 5 (BLK)
   CAMERA GND	No. 4 (GRN)	No. 4 (WHT)
   CAMERA V	No. 15 (WHT)	No. 6 (RED)
   CAMERA VCC	No. 16 (BLK)	No. 3 (GRN)

   Is there continuity?

   YES 

   The CAMERA wires are not open. Go to step 8.

   NO 

   There is an open in the wire(s) between the audio-navigation unit and the rearview camera. Replace affected shielded harness.
