5/5
Flash code 5/5 indicates problems with vehicle engine RPM or the
encoder. Not reported during 2 second power-up.
8
SPEED SENSOR READING INVALID
SPEED
This fault is detected with diesel engines only. The RPM pickup is indicating a
speed that greater than 4000 RPM or approximately 8875 Hz.
SPEED INPUT LOST
This fault is detected with diesel engines only. It occurs if there is no RPM
detected and the oil pressure input is reading above 8 PSI for more than three
seconds. This is probably due to wiring problems at the ground module or a
faulty speed sensor.
6/6
Flash code 6/6 indicates problems with the CAN bus.
10
PLATFORM CAN COMMUNICATIONS
LOST
The ground module or platform module is not receiving CAN messages. This is
probably due to wiring problems between the platform and ground modules.
BLAM CAN COMMUNICATIONS LOST Only occurs on machines with a BLAM. The ground module or BLAM module is
not receiving CAN messages. This is probably due to wiring problems between
the BLAM and ground modules.
CHASSIS CAN COMMUNICATIONS
LOST
Only occurs on machines with a chassis module. The ground module or chas-
sis module is not receiving CAN messages. This is probably due to wiring prob-
lems between the chassis and ground modules.
CYLINDER LOAD PIN CAN COMMUNI-
CATIONS LOST
Only occurs on machines with a cylinder load pin. The ground module or cylin-
der load pin is not receiving CAN messages. This is probably due to wiring
problems between the cylinder load pin and ground module.
EXCESSIVE CAN BUS COMMUNICA-
TION ERRORS
More than 500 Bus Off or more than 500 Bus Passive conditions has been
detected by the Ground Module in the current power cycle.
MAIN ANGL1 CAN COMMUNICA-
TIONS LOST
The control system lost CAN communications with main boom angle sensor #1
(1250AJP only)
MAIN ANGL2 CAN COMMUNICA-
TIONS LOST
The control system lost CAN communications with main boom angle sensor #2
(1250AJP only)
7/7
Flash code 7/7 indicates problems with a motor.
NOT REQUIRED
8/1
Flash code 8/1 indicates problems with the Chassis tilt detection system.
10
CHASSIS TILT SENSOR NOT CALI-
BRATED
The leveling (zeroing) calibration has not been performed for the chassis tilt
sensor.
8/2
Flash code 8/2 indicates problems with the platform load sensing sys-
tem.
10
LOAD SENSOR NOT CALIBRATED
The calibration procedure has not been performed for the load sensor.
