Default SuperNova International

Brake Pressure Warning light is coming on (Along with the ABS) .
Found out how to silence the horn. Was wondering if anyone has experienced this before and what some possible fixes are.

Thanks,

Roy.

My 2008 Supernova ate one under warranty then a second one last year. Dealer only. No fun but it fixed the problem. Entire unit gets renewed. HTH John

Update: drove for 400 miles today with no alarms. Difference was rain and wet roads when alarms sounded and dry roads today.
Thinking I have some exposed sensor connections.

Ours was intermittant for 3 years before it died. Have someone scan the system and look for communication codes with the instrument cluster, or communication to PCM. We cleaned and ohmed everything to no avail. Then it finally died, International installed new unit, all good since.

Thanks for the comment. I figured ours will go eventually. Looks like most have had to replace it.

Well welcome to the ABS club.

Best thing you can do is get your rig over to international Navstar dealer and have them replace the ABS unit. This is been an ongoing problem with these vehicles. The unit goes out causes all kinds of problems. You’ll still have breaking however you’re not half ABS braking. I went through two of these units on a 2008GS 6263.

Very frustrating all of a sudden you see lights and whistle’s and wonder where the hell my brakes went.There is no easy fix to this they need to go in and replace the unit. These units have been going bad on these vehicles as well as on the Nav Star school buses. So it’s not an unknown or uncommon occurrence. In addition it ain’t cheap!

Best of luck it’s not the end of the world but it will cost you a few dollars to get this thing fixed and if you don’t I would not recommend driving your rig around on a long-distance trips.

Good luck like I said it’s not cheap but it’s not the end of the world either.
