I have a PR4500 (I listed under the wrong model accidentally) with intermittent code 132. It is not listed in the service manual. It has a brand new main wiring harness, deadman/brake switch assembly, brake assembly and POT1 and F/R switches are calibrated and good. Raise and lower still work after it codes, but travel speed is slowed. Code will go away after rekey but comes back shortly after while traveling.
