| CAMERA_BIT0 shorted to ground inspection | OFF | Not shorted | |||
| CAMERA_BIT1 shorted to ground inspection | OFF | Not shorted |
Results
- If abnormal, there is a problem in the circuit.
Rearview Camera Inspection
NOTE:
Since there is no direct method to test the inspection item, troubleshooting is performed using a known-good component.
Test Procedure
- Install a known-good rearview camera and attempt to reproduce the failure.
Results
- If the failure is reproduced, there is a problem with other related components.
- If the symptom/DTC goes away, the rearview camera must be faulty.
Center Display Unit Inspection
Test Procedure
- If the other inspection item(s) indicated a normal condition, then it is determined that the remaining center display unit is the cause.
Results
- There is a problem with the center display unit.
