Any other vehicle I would not care about ABS. But my motorhome likes to lock the front brakes because all of the weight is over the rear (dually) axle.
I have a 1994 E350 motor home with 4 wheel ABS and duallys. Before some one says it YES I KNOW IT'S A 94 AND IT IS 4 WHEEL ABS. When I start going down the road the ABS light kicks on almost every time at 5MPH
The codes are:
C1230 Rear speed sensor (put in a new one already, no change)
C1198 Left front isolation/inlet valve coil circuit fault
C1214 Right front isolation/inlet valve coil circuit fault
C1206 Rear inlet Valve Circuit Fault
C1210 Right front Dump/Outlet Valve Coil Circuit Fault
C1202 Rear Dump/Outlet Valve Fault
Thoughts?
Would one start with a new module or start looking at the hydraulic unit?
Thanks in advance!
Because there are circuit faults being cited I'm curious if one or more of the wiring harnesses or connectors haven't failed or developed corroded pins/terminals?
Typically it would be highly unusual for multiple hard parts to fail all at the same time.
Move my post to here under brakes.
I have the 3 wheel abs system that they call 4 wheel abs in 1994 Ford E350 chassis. 1994 Coachmen Catalina Sport 220RK with 39,551 miles on it. Mine is not OBD-II compliant either. I have replaced the rear sensor and it was bad. I put the old sensor in my Explorer and the abs light came on. So I bought one for Motor home and put the good one back in my Explorer. Brakes stop fine its just that darn ABS light that bugs me. My ABS light stays on all the time. It never goes out. How did you pull your codes?
Thanks, Andy
I took my RV to a shop and has a tech pull the codes. My abs light does not come on until the first time I apply the brakes when driving. I have kinda isolated it down to being a fault in the harness or valve coil pack. It doesn't really matter though. No one carries parts anymore. I promise you, you can not find a rebuilt control module or valve pack. The E350 4 (or 3) wheel abs was a special breed. Not even ford carries parts. I have checked all around. We are just going to have to live with a vehicle that is dangerous if towing anything. UGH
