09 4400 Brake / ABS light on

Hi Guys,

I have a 2009 4400 with a Maxforce 9 motor that has developed a problem. When I turn the key on all of the usual alarms and lights come on. I can hear what sounds like two pumps running and when they go off the brake and ABS lights go off. I can then drive the truck (it's a converted ambulance I use to tow my race car) about 10 miles before all the brake / ABS warning lights come on and the alarm sounds. The brakes work fine but the alarm is pretty annoying. I searched on line and found the ABS Module, but at $2,700 I'm hesitant to change it if it's something else.

Any help would be greatly appreciated.

Thanks
Brad

 

Is there a scanner you recommend? I have the standard automotive scanner, but (as I am sure you know) it doesn't work in the 4400. Wouldn't mind having one if I could get one at a reasonable deal. If not, I'll take it by the shop tomorrow. Thanks

 

So I had the codes read and it said I had 74 counts of 57-5. We checked the connectors and they look okay. We are thinking the HPB is bad. Sucks, this vehicle only has 48,000 miles.
