- CHECK FOR CORRECT VIDEO CAMERA OPERATION
- Disconnect the video camera connector.
- 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
- Reconnect the video camera connector. Make sure it seats and latches correctly.
- 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.
