Just an update

I replaced the the resistors and now have the truck working however it comes up with an error 26 solo pilot drives tilts and sideshift working just no lift, can anyone suggest anyhting.

I have tried cards off another truck and the problem is still there.

I tried to set the pot teach in for lift but the system does not see the pot there. I wanted to know if the pot for lift goes through the interface card? As the inteface card did have water damage.
