Battery could be on its way out but a BT can bus controlled truck like the LWE will normally throw its toys out & flag up loads of odd error codes at random if the battery is in poor condition.
Parameter 2 will be the speed.
Does it have a optional turtle button fitted?
Truck serial number & I can look it up on the system.
If you cant get in with the horn button to change them then the parameters are locked & your stuck unless you have a BT can key.
Pin 14 - wire number 58 is the safety arm input on the transistor controller, you should still find the wiring is fitted even if the truck hasnt actually got the arms attached, switch connectors will just be linked out.
