Glenn;
Disconnect the brush wear and temp sensor plugs at the drive motors and operate the traction drive to see if you have normal travel. Question one have you checked the steering switches. Also, do you have a stable 15V from the voltage converter U1 to controller card to speed sensor, to accelerator and to current sensor. The fault code 32 on your truck that was produce in Germany on Jan 2001 is saying to me that the voltage at plug 1x13 pin 24 is out os spec. If you have the Linde Truck Doctor
software connected to the truck's communication plug under the spyglass hour meter you would be able to see if the accelerator is zeroed in and if 15V is there.
