ABS light on RV comes on at will.

Most vehicles with ABS will have speed sensors located on the rear differential, which you found, and one in each hub assembly up front. I have seen some GM vehicles have speed sensors on the rear hub assembly as well. Check the front hub assembly sensors, there should be a two wire harness that is clipped on to your shock mount up by the firewall. If you have an ohm meter you can measure the resistance of the sensor. If open or short obviously it is bad. I don't know the normal resistance of these sensors. Hope I could help, good luck!

if you feel grinding then you have not properly installed the pads
the abs sensor is in the same area so maybe you damaged or partially loosened the sensor

Using the C-Clamp is the proper way to retract the pistons. So it wasn`t your fault for the aABS light.
check the brake fluid level, check the wheel speed sensors connection on all 4 wheels,
Drive vehicle for a few miles too see if the ABS resets itself.
If the light is still on, then have the truck checked with a SCANNER for the ABS problem..

this part is the ABS HCU ( Hydraulic part Unit) ; these break down due to low mileage on the #50 RV Cutaways ( be careful, NOT the same as regular E350). Dealer's do NOT stock this part and the cost is well over $1K !

unfortunatly .it requires a computer to remove the code.if youve done that you have access to one. go to the abs functions and tell it to bleed.

dosen't stop at all or just slow?, if the abs is working then you should feel the pulseing in the brake pedal just before tire lock-up, the tires will not lock-up with abs fully funtioning unless all four tires or two are in lock-up depending on the abs application, if abs fails it reverts it self to regular braking ability, hope this helps

there is no actual switch,there are speed sensors on the wheels and a contoller on the brake valve.have it put on a scan tool that can check abs systems to find out what needs repair.good luck.(did you check you fuses,fuse location and discription is in the owners manual,see index in the rear)

yeah my abs has flashed for years now= bad sensor wont affect your driving

The sensor is located I believe on the differential housing,could be faulty or corroded

I also have a 96' shasta RV 26' E350 Ford chassis... ABS light comes on whenever it feels like it. We have 20,000 miles on the RV. We love the Motorhome but am constantly worried about the light. Our mechanic said not to worry about it.. Not worth the expense to fix it. anyone have a clue? grandmanomi
