HOSE AS 2258060 - Caterpillar

Problem Isolation
For Step 1 and Step 2 refer to Testing and Adjusting, "Electrical Connector - Inspect"
Ensure that the left receiver cables are not damaged and that all connectors are secure with no bent or broken pins.
Ensure that the right receiver cables are not damaged and that all connectors are secure with no bent or broken pins.
Check the GPS diagnostics for the left receiver. Refer to Systems Operation, Troubleshooting and Testing & Adjusting, "Operational Problems" for details of running receiver diagnostics.
Swap the right GPS receiver with the Left GPS receiver.No GPS Data (Right)
The GPS receivers are computing high accuracy position data for the left antenna, but not for the right antenna.Probable Causes
Cable or connector problem to the right receiver
Bad right receiver
Communication disruption within the GPS receiver
Receiver faultProblem Isolation
For Step 1 and Step 2 refer to Testing and Adjusting, "Electrical Connector - Inspect"
Ensure that the right receiver cables are not damaged and that all connectors are secure with no bent or broken pins.
Ensure that the left receiver cables are not damaged and that all connectors are secure with no bent or broken pins.
Check the GPS diagnostics for the right receiver. Refer to Systems Operation, Troubleshooting and Testing & Adjusting, "Operational Problems" for details of running receiver diagnostics.
Swap the right GPS receiver with the Left GPS receiver.Low Accuracy (GPS)
The GPS receiver is generating positions with errors that exceed the current GPS Error Limit set in the AccuGrade System.Probable Causes
Power to the GPS receiver was recently applied or cycled
Poor satellite geometry due to the GPS constellation or from physical obstructions
Poor radio coverage
Radio receiving other base station corrections
The machine is a long distance from the base station
GPS receiver fault
Incorrect "GPS Error Limit" set in the AccuGrade System (consult your supervisor)
Insufficient satellitesProblem Isolation
Confirm that the power to the GPS receiver is good and that the connectors are secure.
Ensure that the antenna cables are not damaged and that all connectors are secure with no bent of broken pins.Refer to Testing and Adjusting, "Electrical Connector - Inspect"
Check the GPS diagnostics information. Refer to Systems Operation, Troubleshooting and Testing & Adjusting, "Operational Problems" for details of running receiver diagnostics. Verify the left antenna values for Satellites Used, PDOP and GPS error. For accurate GPS positions to be generated you need 5 or more satellites and the PDOP less than 7. As the PDOP decreases and the number of L1 and L2 satellites increase the GPS error will decrease. Check the status of the right receiver.
Ensure that the GPS receivers are not obstructed by buildings, trees, or other objects that would impair the line of sight for the GPS receivers.
Verify that, on the "Radio Data Link" screen, integrity is over 85%. Intermittent or sporadic corrections can result in increased GPS position error.
Confirm that
