To start with it had no hydraulic functions at all. Troubleshoot and found the pump card had failed. Installed a reman pump card. Got the normal code. Used the LX hand set and changed setting 17. Plugged harness back into card and everything worked. Sat on the seat lift worked one time, then no lift. I can hear it activate but know Pump motor. If I activate pump with another function lift will work. Then I found if I unplug the lowest plug on the pump card and plug back in, the lift function works until I sit on the seat and activate the seat switch, or shut the key off and restart.
This does not have a contactor for the pump motor. And I have no codes.
Let me know if you need anymore info.
Appreciate the help.
Thanks.
