Working on a 7BRU23, I changed the print board display but now I lost the reach/retract function. Configuration C8 is No Straddle, Tuning C5 is two speed, Both solenoids are OK, Voltage are ok 22v, but Lift Amplifier turns pump only between 9-12% RPM. All other aux hyd functions are OK turning pump at 30% RPM. Scanning pulses I can see the signal arriving ok to LPA. Does anybody some idea about this trouble? Thank you

Thanks

Rich,
61 is steer error, 69 is steer limit feedback signal error, 51 is traction proximity sensor error, and 57 is traction pot voltage out-of neautral during POST. Hopefully this helps.

I could only find 51(vehicle speed sensor open circuit) and 61(load sensor circuit open) I have had a similar problem before and it ended up being the battery Rich
