Hello , new to the page here, hope to get some help.
Have a JLG 2630ES that just decided to stop driving all of sudden, scanner shows code 256 DRIVE PREVENTED POT HOLE NOT ENGAGED one was a little sticky so did a hale Mary and replaced both switches with the new stile. no difference, scanner shows left switch operating opposite of the right, Switches are operating properly along with all linkages, have voltage threw the switches back to the lower controller ( switches are wired in series ) I did notice that if I disconnect the proximity switch the code goes away, and it will start to drive, but the left brake will lock after about 3 seconds

Nice to hear...keep an eye on the battery trays, they are made of plastic and the corrosion and weight crack the upper sections a lot..I've dropped a few in my days..barely missing feet
Thanks for the help, I went back threw the menu of the scanner, and noticed the proximity sensor was shown as not installed. Corrected the description and it worked, thanks
These lifts pots can be a hassle...if you replaced them..make sure you changed wiring..they come set normally open I think and need to be normally closed...then verify only at around 6 feet both pothole legs come off both switches all the way..I've had a leg not opening all the way all the time..I ended up replacing both and readjusting both..then verify pox switch is working properly...use analyzer to change country and model..then power off..turn back off...reset to original
