Pinpoint Test J

CHECK AND CLEAN THE REAR VIDEO CAMERA LENS
1. Clean and make sure the rear video camera lens is clear of any debris.
2. Test the video camera system and verify the video camera image.
Is the video camera concern still present?
- Yes: GO to 2 .
- No: The system is operating correctly at this time. The concern was caused by a dirty video camera lens.

CHECK FOR CORRECT VIDEO CAMERA OPERATION
1. Disconnect the video camera connector.
2. Check for:
  - corrosion (install new connector or terminals - clean module pins)
  - damaged or bent pins - install new terminals/pins
  - pushed-out pins - install new pins as necessary
3. Reconnect the video camera connector. Make sure it seats and latches correctly.
4. Operate the system and determine if the concern is still present.
Is the concern still present?
- Yes: INSTALL a new video camera. REFER to Video Camera .
- No: The system is operating correctly at this time. The concern may have been caused by the video camera connection. ADDRESS the root cause of any connector or pin issues.
