Have you figured it out yet? Pulse Width Modulation PWM From googling it appears to be an AUX switch problem. Do you have a 'thumb' switch? Have you checked fuses?

this is a do not sweat it code.. it usually means . the wiper switch on right thumb paddle going bad. I suppose further explation may clear it up. pwm gives us the ability to feather our aux hyds ( as in slow movement of attacments like the gate on a tree spade) rarely is it used especially on an ex. usually we are looking for on or off. on an exv unless using specific attachments tha require the ability to FEATHER, disregard, this code and go on. a no harm no foul.
