The truck has 4 way hyd's. with the mini-levers. The **** broke for the 4th control, ordered new mini-lever and installed. All 4 hyd. functions worked for about 15 min., then the new 4th control stopped working and this code flashed. Plugged in the old lever, which did work even though the **** was broke, and all hyd. controls stopped working. Plugged in the new one again and all hyd. control stopped working. Leave the 4th control disconnected and the other 3 work. Does the truck need to be set up to recognize a new switch? Seem like a defective switch? Any info. would help.
