I am seeing a similar issue with my Hyster J30ZT.

We put in a new hydraulic motor, but now have this 91 error code. Lift only drives at 1/2-3/4 speed but otherwise works.

Control wires were slightly different on new motor with 1 additional wire. Wondering how to proceed?

Fact of the week
Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
