I am getting codes a6-1,a6-3,a6-5,a6-6,e-1, and e0-4. I put new o-rings in the hydraulic control valve and replaced the tips on the mp1 contactor that melted off. Turned the truck on and got all of these codes. I replaced the wire harness, lift lock solenoids, tilt switches, all of the lift switches and harness, pump transistor and diode,st card, dc/pd board, and the scpu board. I made sure no wires were pinched, I traced every wire in the truck and found nothing abnormal. I ordered a new pump current sensor that will be in today. I am lost on what to do next. I had a toyota trechnician work on it and he is confused as i am. I am wondering if anyone out there has had this problem and point me in the right direction. Thanks Brad
