I think they are referring to the backup alarm relay.

No more 65299 code only have the 13368 code that shows up as soon as I turn the key on. You had mentioned that it was a motion relay ? What does that do? And do I need to replace it?

35.2 should not trip out the controller. I would check all the connections at the controller.

I do believe it’s the battery, it goes from 38.6 down to 35.2 when I dead head the tilt.

Have you checked the battery voltage under load?

The relay should be under the floor plate just to the right of the left tilt cylinder under a black cover with a thumb screw on top. the motion relay is the one closest to the front of the truck.

It has the feature of auto shut off on the lights. The wrench flashes and 13368 shows up when you first turn the key on and you have to push the arrow button to get the password screen to put my password in.

Does the truck have auto activated lights? I think that code is for this option. If the truck does not have this option I would ignore the code. A fast drop in the battery voltage will cause all kinds of odd codes to come up.

Thanks for the info, Do you happen to know where the relay is located? tried to find it in the parts book but had no luck.

13368 is shorted or open circuit in motion relay.
652299 is controller failure, this can be caused by low battery voltage. I would check out the battery.

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

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.
