Crown SP3400:
Sp3400 steering to the right on its own

I will say, im a seasoned crown tech and i have a unit that has been kicking my *** pretty hard. No codes, but unit will intermittently click the steering angle to the right till it eventually hits the stops. the steer motor will get very hot just sitting there while "on" resistance in mast cables are good, steer encoder and feedback encoder, bushings and sprimgs have been replaced, steer module and motor have been replaced, distribution panel replaced. Once i replaced a visibly good drive tire the problem went away for a month but now is back again..

The module has to see an input to send an output to the steer motor. Iv'e seen an Access1 do this, but check the steering wheel encoders first. If you have a sister truck, it would be easy to swap modules to see if the condition follows a bad module

Hey, did you fix it? List time I saw this it was a steering module. If there is no input request to the steering module and yet the drive unit is turning I would replace the steering module. You can watch inputs with your service terminal.
