I have to try and find the brand of my abs system although I think I am getting blink codes in pairs as well. MHrookie I am retrieving codes using the abs push button that lets the system send blink codes. Ivylog they fit but it was close! I just can not believe the coincidence. Just after tire install light came on. The investigation continues!

Thanks guys. Inspected the sensors and harness nothing obvious stands out. The sensor seems to be seating correctly. I have not tried to clear the light using the button yet. On that note do you have an idea where I can find that procedure?

Hi everyone... my coach is a 2002 Holiday Navigator 40PBDD on a roadmaster chassis. Per the tire placard tires size is 295/80/22.5. After further researched I opted to change the steer tires to 315/80/22.5. I am happy to report the ride is alot nicer as is my peice of mind with a bigger 20 ply steer tire. The down side of this is now my abs light is on which I am certain has to do with wheel speed sensors since the front tires are larger than the rear. I pulled some blink codes so far 4 6 17 are the main codes I am getting. My question to the group - I have heard of many others doing this change to steer tires. Is there programming I should have done to account for the difference in tire size? Thanks for the help!

I cannot give you technical details surround the why but I can tell you I spent alot of time and money trying to first get my Leece Neville rebuilt with cheap internals " I did not know any better at the time " That failed instantly. I then used the same Delco 28si and I had the same exact outcome. The engine would not shut down. I then started to diagnose the ignition switch. I swapped the switch and still had the same issue. I finally took the advice of this forum and many others. Took my Leece Neville to a very reputable shop in my area. Spent $1000 for a all original leece neville internals. Completely rebuilt and upgraded with heavy duty. Installed and never had an issue again. From my understanding the 28si can only be used when the Duvac system is eliminated. Hope this helps!

Hey- So I also have an 500 ISM. I just went through a large issue with alternators that caused a lot of digging in other areas all unnecessarily. The alternator you show in the picture is exactly the one someone sold me. They claim it’s Duvac and it is not!!! I also replaced my isolator which was not needed. You must get a true Duvac alternator. Is that the alternator they replaced? Or is that the old unit?
