Can You Complete A Zero Point Calibration Without Being Hooked Up To A Truck

Question:

Can I perform a zero point calibration or rehoming procedure, without being attached to our truck? Here’s my situation….we have sold our truck and the 5th wheel. However the truck got picked up before the trailer. The trailer is in a storage facility with the left and rear flashing red on the panel. Thank you in advance for the help! ??

Yes, the zero point calibration for a Ground Control # LC358590 would need to be done while not coupled to a truck, otherwise it could potentially lift the truck or push down on the truck while trying to level and damage something. One of the biggest issues we've encountered with this system is a lack of power so you'll want to ensure that the trailer batteries are fully charged to prevent any issues with the system.

I've listed the steps below to help walk you through this process.

1. In manual mode, run the jacks to level the trailer. This is best achieved by placing a level in the center of the trailer and leveling it both front to back and then side to side. (See “Basic Jack Operation” for instructions on how to manually operate the system).
2. Once the trailer is level, turn off the touch pad.
3. With the touch pad off, press and release the “FRONT” button five (5) times and then press and release the “REAR” button five (5) times.
4. The touch pad will flash and beep and the display will read “ZERO POINT CALIBRATION ENTER to set, Power to Exit”.
5. To set the current position as the zero point, press the “ENTER” button.
6. LCD display will read “Zero point stability check”.
7. LCD display will read “Zero point set successfully” once process is complete.
8. The system will set this point as its level state and the touch pad will turn off.
