YALE Pallet Lift Truck Fault Codes DTC
Error: no LEDs or LCDs on
What the issue is: Inoperative
Cause of Problem: B+ and / or B- missing at controller, defective battery charger, or defective battery charger
What to do: Ensure the battery is connected, the key switch is on, and the brake override circuit is in the run position; also test your battery charger and motor controller and replace any
nonworking parts
Error: no LEDs or LCDs on
What the issue is: Forklift functions as normal
Cause of Problem: open connection between display and controller, defective display, or defective LEDs
What to do: make sure harnesses are connected at MDI and connector B on controller; test the dash display by connecting a handset to it and testing for communication; test LEDs by disconnecting
them, connecting the handset, and testing the handset; replace any non-working parts
Error: no LEDs or LCDs on
What the issue is: Forklift functions as normal
Cause of Problem: Because this condition is similar to the last, it will take a handset to determine its cause. If the handset displays “NO COMMUNICATION,” the controller is defective.
What to do: replace controller
Error: no alarm
What the issue is: Traction and hydraulic functions not working
Cause of Problem: improper startup sequence by jack operator
What to do: check brake switch, accelerator, steer handle, and hydraulic inputs
Error: AL66
What the issue is: Hydraulic function not working
Cause of Problem: battery voltage is low or controller voltage calibration is incorrect
What to do: Charge or replace battery; otherwise, use handset to determine the voltage read by the controller and compare it to an actual voltmeter reading; replace controller if the two readings
differ by more than 1.5 volts
Error: AL99
What the issue is: Traction and hydraulic functions not working
Cause of Problem: incorrect battery selected, damaged battery, or damaged connection to batter
What to do: check that you have the right voltage for your truck, manually check the voltage of your battery, inspect it for any damage, and check its connecting crimps and cables for damage as
well
Error: AL01
What the issue is: Traction and hoist functions not working
Cause of Problem: control card throttle or lift/lower calibration is out of range; control card is damaged or defective
What to do: Use the tester function on a handset to see if either calibration is greater than 1 volt at neutral; replace control card if damaged or defective, which can be checked by seeing if
both “forward switch” and “backward switch” are on at the same time when testing
Error: AL01
What the issue is: Traction and hoist functions not working
Cause of Problem: incomplete connection between control card and controller; traction reversing switch not connected; damaged or defective tiller card
What to do: Check connections between control card and controller; use a handset to test for operation of traction reversing switch; replace control card if tiller card is damaged
Error: AL02
What the issue is: Traction and hydraulic functions not working
Cause of Problem: main contactor tips are welded closed or motor field circuit is broken
What to do: disconnect power leads at contactor and test for an open circuit; check connections between motor field and controller
Error: AL04
What the issue is: traction and hydraulic functions not working
Cause of Problem: damaged connection to lowering valve; damaged lowering coil or lowering valve cartridge
What to do: check electrical connection between valve coil and controller; check lowering valve coil for resistance, replace if not approximately 17.7 ohms; replace lowering valve cartridge if
necessary
Error: AL05
What the issue is: traction and hydraulic functions not working
Cause: damaged connection to brake or brake coil damaged
What to do: check connection between electric brake and controller; check brake coil for resistance in both directions and replace if not between 27.36 and 30.24 ohms
Error: AL06
What the issue is: Traction and hydraulic functions not working
Cause of Problem: Damaged connection to traction motor; traction motor armature resistance is too low; field wires are loose or damaged; motor field winding is shorted or too low.
What to Do: Check electrical connection between traction motor, field wires, and controller; check traction motor armature for shorts; check motor field resistance and correct if not between 0.5
and 1.5 ohms; check contactor coil for resistance of 52 ohms
Error: AL07
What the issue is: traction functions reduced below 14°F or above 167°F and not working above 194°F
Cause of Problem: controller temperature is too hot or cold; controller temperature is not calibrated correctly; controller sensor or controller itself is damaged
What to do: move truck to a warmer or cooler location; use a handset to check that controller temperature matches room temperature (if not, replace controller)
Error: AL8
What the issue is: traction and hydraulic functions not working
Cause of Problem: over current in driven component
What to do: check main harness for damaged connections to main contactor, brake, and electric valve coils; check contactor, brake, and electric valve coils for correct resistance (52 ohms for
contactor, between 27.36 and 30.24 ohms for brake coil, and 17.7 ohms for electric valve coils)
Error: AL10
What the issue is: Traction and hydraulic functions not working
Cause of Problem: controller is damaged; damaged wire connection; short circuit in harness; ground between motor windings and chassis; motor field winding is shorted to chassis; field current
driver circuit has failed; watchdog hardware circuit is damaged
What to do: Cycle key switch off and on and replace controller if problem not solved; check wire connections at contactor, pump motor, and traction motor; check main harness for shorts; check for
grounds or shorts between motor windings and chassis; check motor field resistance (should be about 1.5 ohms); measure voltage between F1 and B- and F2 and B- on field current driver (should be
half the voltage between B+ and B-)
Error: AL94
What the issue is: Traction and hydraulic functions not working for one minute.
Cause of Problem: No fault is occurring. The controller is installing hour meter memory from MDI display if controller has been replaced.
What to do: No solution necessary. Fork truck will operate as soon as data transfer is complete.

For GM 4.3L gasoline and LPG engines the engine should idle at 725 to 775 rpm with no pedal and continuing to the governor speed which should be 2375 to 2425 rpm at maximum full pedal. Is the throttle mechanism operating smoothly/tracking with accelerator operation? YES: Problem corrected. Resume operation. NO: Ensure truck power is OFF. Clean any fuel residue from mechanism and go to Step 3. 3. Check for proper operation of the throttle body and the ECU mechanism by exercising the accelerator pedal with the vehicle in neutral. For GM 2.4L gasoline and LPG engines, the engine should idle at 775 to 825 rpm with no pedal and continuing to the governor speed which should be 2675 to 2725 rpm at full pedal. For GM 4.3L gasoline and LPG engines the engine should idle at 725 to 775 rpm with no pedal and continuing to the governor speed which should be 2375 to 2425 rpm at maximum full pedal.
