Troubleshooting: Cable Troubleshooting 93
TROUBLESHOOTING
When large sections of NCVs are not communicating, inspect those items along with fuses and large electrical
connections.
If intermittent power to the NCVs is the cause of the issue, or if NCVs are disconnected and re-connected during
the troubleshooting process, NCVs will appear back online after repairing the system, but DTC errors will still exist
until the system power is cycled off then back on.
OTHER USEFUL TESTS
Calibrate NCVs should be used after swapping NCVs around to locate problems, or after replacing NCVs. This will
ensure the NCVs are properly numbered in the system for turn compensation, section shutoff, and error detection.
Reboot Product Controller can be used instead of cycling key power to reboot and reinitialize communication to
the RCM - Sprayer ECU and NCV bus.
CABLE TROUBLESHOOTING
TROUBLESHOOTING NCV CABLE CONNECTIONS
Nozzle control valve cable troubleshooting may require the system to be powered on and the NCVs disconnected.
Disconnect the boom cable from the NCV. Hold the connector so that the retention clip is facing toward the 12
o’clock position.
