SECTION 1 - FAULT DICTIONARY AND SELECTED TROUBLESHOOTING
Test
Are any of the following faults active on the
machine? BOOM ANGLE SENSOR #1 (or 2)
COMMUNICATIONS FAULT
Is there any lose mounting hardware, etc.?
Check the sensors aren't swapped by unplug-
ging tower boom angle sensor #1 (Right)
[X099]. Does the BOOM ANGLE SENSOR #1
COMMUNICATIONS FAULT show?
Are both sensor angles approximately -4.3° ±
1.5°?
Did boom calibrate successfully?
Test
Are any of the following faults active on the
machine? BOOM ANGLE SENSOR #2 (or 1)
COMMUNICATIONS FAULT
Is there any lose mounting hardware, etc.?
Check the sensors aren't swapped by unplug-
ging tower boom angle sensor #2 (Left)
[X100]. Does the BOOM ANGLE SENSOR #2
COMMUNICATIONS FAULT show?
