ABS Light check

[Skipjack]

Should my ABS light on my instrument panel illuminate when I first turn on my ignition?.

All my other dash indicator lights do, but my ABS does not. (HR 2003 Roadmaster Chassis R4R)

Yes.  That is to let you know that those lights are working, hooked up to what generates the light.  Chuck B 2004 Windsor

Thanks

The ABS light as well?

I have had my coach for a couple of years and never thought about it.

I have had some recent overheating in my front rotors/calipers, and it made me think about the ABS system

Yes, ABS light should come on for couple seconds or so while running self test. May want to check the bulb.

I am not sure if when you turn on ignition switch if it actually does a "systems check"?. Typically it was a way to check that the indicators light bulb did in fact turn on n was not burned out.

Yeah, appears to be a bulb and ABS malfunction check. Either way, the light should come on. Also may want to check ABS related fuses, I've got 3 in the ignition fuse section of FRB.

From my Bendix manual:

ABS Indicator Lamp
This lamp is the primary indicator of ABS system
condition. Under normal conditions, the ABS lamp lights
steadily for a two-second bulb-check whenever the
switched ignition is ON. The ABS lamp turns OFF after
the bulb-check if there are no ABS malfunctions
present. If the indicator remains ON, after the
bulb-check, or lights during vehicle operation, it
indicates the ABS requires service.

Thanks a bunch guys.

That is what I expected.

I did have a couple of the relays go bad on me as well in the Monoco 3 box up front. (One was related to the IGN, and none of the gauges would work) 

I just found another relay box at the rear of the coach (Monoco 4) and it contains relays and fuses for the ABS. I think I am going to check this out

thanks again
