Hi Surinder, thank you for asking this question. This is definitely something we can help you with. Please feel free to call us directly at 510-632-3535 and our service department will be able to assist. Our technicians would have to look at it, but this is definitely something that can work again!
If you mean Wabco On Guard, I'd check with whoever put the system in, as eld is not supposed to interfere with existing systems.
Thanks! Your answer is awaiting moderation.
