traction controller

I replaced the traction controller on a crown PE4000 with a new one after the old one gave out, and now i get a code 33 as well as a code 21 with no travel. I have gone through the steps in the manual and everything checks out. I can not figure out what is going on or why it would code out after replacing the controller.

If the old controller was original to truck and the accelerator potentiometer was never updated to new 3 wire one then you will have to get a Crown tech to come out and adjust the throttle type and maybe move some wires around per the update

Fact of the week
Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
