- Ensure that the video connector on the back of the display is fully seated.
- Check for power out of the display for all of the cameras. Check contact 1 (+24 VDC) and contact 2 (Ground).
Individual Camera has no Video
- Check for power at the suspect camera. Check contact 3 (+24 VDC) and contact 4 (Ground) at the connector on the camera.
- Check the wires to the display for the suspect camera.
Video of selected Camera does not Correspond to the Correct Side of the Truck
- The connections in the electronics bay at the rear of the cab for the video harness are incorrect.
- Channel 1 = Front Camera
- Channel 3 = Rear Camera
Note: The video harnesses have connections at the camera harness, the electronics bay, and the cab. On larger machines, there may be two sections of harness between the electronics bay and the camera.
The display should power up when the key switch is turned to the ON position. If the display does not power on when the key is turned to the ON position, check for the following problems.
- Ensure that the center connector on the display is fully seated.
- Check for +24 VDC at contact 11 (+Battery) and contact 12 (Ground), if voltage is present the display has failed. If voltage is not present, check the power connections in the electronics bay and ensure that the circuit breaker is set properly. Refer to the Electrical System Schematic for the system.
The Screen of the Display is too Dim
The brightness is set to the minimum setting and auto dimming is activated in the configuration screen.
- Use the brightness button and the arrow button in order to increase the brightness level.
The Screen of the Display is too Bright
The brightness for the display may be set too high.
- Use the brightness button and the arrow button in order to lower the brightness of the display.
The Colors on the Display Appear Washed Out and Dim
The display is in night mode.
- Press and hold the brightness button for 2 seconds in order to disable night mode.
A diagnostic code or an event are active.
- Check the diagnostic screen for the active code. Refer to the Troubleshooting, "Diagnostic Codes" section of this manual for additional information.
This indicates that the system has transitioned to the standby mode after the machine has traveled
No Video or Video does not Match the Selected Machine Position
Refer to the "Video" section of this document for additional information.
Object Detection System is Detecting False Objects
If the object detection sensors are not adjusted correctly or there are third parties or Caterpillar attachments installed in the path of the object detection sensor beam, the system may detect objects when no objects are present. The following solutions may be helpful in determining the cause.
Use the parameter status screens in Cat ET (version 2010C or later) in order to check the object detection sensors that are detecting an object to determine which object detection sensors are seeing an object. Then, investigate to determine what the object detection sensors are detecting. False detections can be caused by any of the following items:
- The ground (if there is an upward slope the object detection sensor will see the ground).
- Lights that are mounted to the machine.
- Attachments that are mounted near the object detection sensors.
- Loose harnesses hanging near the object detection sensors.
- Tires can possibly cause false detections when turned outboard.
- Improperly adjusted object detection sensors.
- Side object detection sensor connectors are plugged into the wrong object detection sensor. (that is, top object detection sensor plugged into bottom object detection sensor connector on harness).
