Been working on this for few weeks. before it has a bad Acceess 3. so i replaced it with the new one. Calibrated. and the Unit worked. Hydraulic is working good. but the Traction Speed is too low. as i said. i already calibrated it. i jacked the forklift so i can freewheel both traction motor. and the right motor seems to be working at the Default Speed/Normal. But the Left motor is very slow. there is no Fault Code showing at the Display. the E-Breaks are working fine too.
I already replace the left motor since i have 2 same unit in our workshop. but still same problem.

I have the same SC4500 but on mine the right motor is on a go slow and the left is normal. Last event code is 303. It doesn't come up with a fault though. I don't have a manual for this machine so not sure how to calibrate it.
There is a small black wire that is on the left traction motor that came loose on my 4500 sc that caused the motor to run at about half speed. It was quite confusing since we were changing the brakes and it mimicked the brakes getting caught up.
Did you run through all the settings both features and performance. Also did you make sure it was in P1 not P3 on display.
Make sure the correct model is entered, then calibrate the steer pot.
