   -3. Wait for at least 6 seconds.

   -4. Check for hard error codes .

   Is DTC 2608 indicated?

   YES 

   The failure is duplicated, go to step 2.

   NO 

   Intermittent failure, the system is OK at this time.

2. Determine possible failure area (CAMERA_ADPT line, others)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Disconnect the following connector.

   Rearview camera 8P connector

   -3. Turn the vehicle to the ON mode.

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

   Test condition	Vehicle ON mode
   	Rearview camera 8P connector: disconnected
   Test point 1	Rearview camera 8P connector No. 6
   Test point 2	Body ground

   Is there about 5.0 V?

   YES 

   The CAMERA_ADPT wire is OK. Go to step 4.

   NO 

   Go to step 3.

3. Open wire check (CAMERA_ADPT line)

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

   Test condition	Vehicle ON mode
   	Rearview camera 8P connector: disconnected
   Test point 1	Audio-navigation unit connector C (32P) No. 16
   Test point 2	Body ground

   Is there about 5.0 V?

   YES 

   Repair an open in the wire.

   NO 

   Replace the audio-navigation unit .

4. Determine possible failure area (rearview camera, others)

   -1. Turn the vehicle to the OFF (LOCK) mode.

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

   Test condition	Vehicle OFF (LOCK) mode
   	Rearview camera 8P connector: disconnected
   Test point 1	Rearview camera 8P connector No. 5
   Test point 2	Body ground

   Is there 1.0 Ω or less?

   YES 

   Replace the rearview camera .

   NO 

   Go to step 5.

5. Open wire check (SH_CAMERA line)

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

   Test condition

   Vehicle OFF (LOCK) mode

   	Rearview camera 8P connector: disconnected
   Test point 1	Audio-navigation unit connector C (32P) No. 28
   Test point 2	Body ground

   Is there 1.0 MΩ or more?

   YES 

   Replace the audio-navigation unit .

   NO 

   There is an open in the wire(s). Replace the affected shielded harness.
