1-2 Throttle Fault 1
Description Throttle fault
Setting
Conditions
Throttle input voltage out of range for the condition
When Monitored
Always
Possible Causes
• Throttle input wire open or shorted
• Throttle pot defective
• Wrong throttle type selected
Initial Action Make sure the drive paddle is in neutral position, and key-cycle the machine
Troubleshooting Steps
1. If error code 3-1 or 3-5 is being reported, diagnose that error rst.
2. Power the machine and with the drive paddle in the neutral position, check the voltage between
contacts 3 and 4 of the drive controller connector.
− If the voltage is at or near 2.5 volts (within throttle deadband) and the error persists, replace the drive
controller.
− If the voltage is at or near 0V or at or near 5V, see step 3 to inspect the potentiometer wiring.
3. Check the potentiometer.
a. Disconnect the X105 connector of the control handle (operator’s controls).
b. Check the resistance between contacts 1 and 2, 1 and 3, and 2 and 3 (respectively) of the X105
connector of the control handle.
– If any measurement is open circuit (greater than 5K ohms), repair or replace the throttle
potentiometer and/or wiring.
– If any measurement to contact 3 results in a reading of at or near 0 ohms, move the drive paddle
position and conrm the measurement. If the result does not change, replace the potentiometer.
– If all 3 measurements are not at or near 0 ohms, the potentiometer is not at fault. Continue to step
4.
4. Check the harness between the drive controller and the control handle.
a. Reconnect the X105 connector at the control handle.
b. Disconnect the X30 connector at the drive controller.
c. Check the resistance between contacts 3 and 4, 13 and 4, and 3 and 13 (respectively) of the X30
connector of the at the drive controller.
– If any measurement is open circuit (greater than 5K ohms), repair or replace the harness between
the drive controller and control handle.
– If any measurement results in a reading of at or near 0 ohms, move the drive paddle position and
conrm the measurement. If the result does not change, the harness is shorted. Repair or replace
the harness.
