1.136 INVALID ANGLE SENSOR #1 MODEL

Flash Code: 8-4
Invalid angle sensor #1 model. The tower angle sensor #1 (Right) is sending 10 bits of data instead of 11 bits of data. The
sensor must be replaced.
Note Pretest Instructions
1.136.1 Read fault log.
1.136.2 Plug the right tower boom
angle sensor connector
[X099] into the tower angle
sensor #2 and the left tower
boom angle sensor connec-
tor [X100] into tower angle
sensor #1

1.137 INVALID ANGLE SENSOR #2 MODEL

Flash Code: 8-4
Invalid angle sensor #2 model. The tower angle sensor #2 (Left) is sending 10 bits of data instead of 11 bits of data. The
sensor must be replaced.
Note Pretest Instructions
1.137.1 Read fault log.
1.137.2 Plug the left tower boom
angle sensor connector
[X100] into the tower angle
sensor #1 and the right
tower boom angle sensor
connector [X099] into tower
angle sensor #2
