Chassis Tilt Sensor Not Calibrated; Chassis Tilt Sensor Not Gain Calibrated; Chassis Tilt Sensor Out Of Range; Cold Start Advance Solenoid Open Circuit - JLG 1250AJP Troubleshooting Manual

SECTION 1 - FAULT DICTIONARY AND SELECTED TROUBLESHOOTING

1.63 CHASSIS TILT SENSOR NOT CALIBRATED

Flash Code: 8-1
Chassis tilt sensor not calibrated. Notification that the chassis tilt sensor calibration information has been lost. Machine will
indicate that it is tilted at all times. Perform tilt calibration. See 5.7 Calibrating Tilt Sensor on Pg. 307.

1.64 CHASSIS TILT SENSOR NOT GAIN CALIBRATED

Flash Code: 9-9
Chassis tilt sensor not gain calibrated. Chassis tilt sensor calibration information has been lost. Machine will indicate that it is
tilted at all times. This calibration data is programmed into the ground module during its manufacture, not in the field.
Note Pretest Instructions
1.64.1 Cycle power

1.65 CHASSIS TILT SENSOR OUT OF RANGE

Flash Code: 0-0
Chassis tilt sensor out of range. Chassis tilt sensor has indicated a tilt angle greater than 19° for more than 4 seconds.
Note Pretest Instructions
1.65.1 Put machine on level sur-
face
1.65.2 Perform Tilt calibration. See
5.7 Calibrating Tilt Sensor
on Pg. 307.

1.66 COLD START ADVANCE SOLENOID OPEN CIRCUIT

Flash Code: 3-3
Cold start advance solenoid open circuit. This fault should never occur on properly configured machines. Reload ground
module software or replace the ground module.

1.67 COLD START ADVANCE SOLENOID SHORT TO BATTERY

Flash Code: 3-3
Cold start advance solenoid short to battery. This fault should never occur on properly configured machines. Reload ground
module software or replace the ground module.

1.68 COLD START ADVANCE SOLENOID SHORT TO GROUND

Flash Code: 3-3
Cold start advance solenoid short to ground. This fault should never occur on properly configured machines. Reload ground
module software or replace the ground module.

1.69 COOLANT TEMPERATURE SHORT TO GROUND

Flash Code: 4-3
Coolant temperature short to ground. This fault is only active for machines configured with older non-ECM Deutz engines.
The engine coolant temperature input [X001.14] is shorted to ground.

1.70 CYL ANGLE SENSOR/SW DISAGREEMENT

Flash Code: 8-4
Tower cylinder angle sensor/switch disagreement. The BLAM module reads the tower lift cylinder angle from the tower lift
cylinder angle sensor [X092]. The BLAM module transmits this angle over the CAN bus to the ground module. As a commu-
