Yale YALE:
Code 40073 Center Angle Fault

I have a Yale model NR045EBNS36TE125 that is displaying code 40073. I have researched but cannot determine what this means. The truck will not move and makes a loud high pitch sound when turned on. Any suggestions as to what this could be?

Thank you for your answer. We have 2 trucks displaying this error. Checked both. We were able to troubleshoot with your instruction and bring one back into operation. The other has a bad steer motor.

Jeff,

The proximity switch that reads the target plate of the drive unit, is not working or failed. Make sure the target plate is still mounted under the drive unit. Possible issue with steer controller. Look at the inside of the drive compartment. To the left of the drive motor you should see a light. That is your prox switch. If the lift is dirty, you may need to blow it off. If you do not see a light, switch might have failed, or controller is bad. The steer motor may be causing the noise. The steer motor is on the right side of the drive motor and prox switch is directly to the left of that. Since you are hearing a high-pitched noise, remove drive motor with all wiring still connected. Turn key switch back on and see what the motor does. Good Luck

The hard to do we do right away. The impossible just takes a little longer.
