Sounded neat but I know its not supposed to be this loud. You know, the pulse that makes it feel like your brakes failed? I did forget get to mention a few things i guess. I think my post was extremely too vague and short. This happened to a good friend of mine. Rather than enter a lengthy debate with me having to quash several fallacies, I'll extend a warm but not fuzzy welcome to the forum. The lamp shall remain illuminated as long as such a malfunction exists and power is supplied to the antilock brake system.

Car also got really loud. How you go about doing this depends on what motor you have, but most are going to require that you hook up the diagnostic computer to it. I look forward to hearing more from you. To pull info out of the diagnostic port, i know bendix makes a plug in type light tester that will kind of lead you in the right direction. I am open to suggestions. Have you checked the brake adjustment and if there are any leaks? They've been fairly reliable with only two failures in over ten years.

I will probably just get it. We have had some new Scanias at work when I use some of our trailers I have noticed that the abs light for the trailer lights up on the dash with the warning of an abs fault. In the last five years, we've replaced approx. Communicating over the turn-signal circuit, it also sidesteps the problem of legacy trailers without blue lines.

The emergency brake does not run on the same system as the main brake line, but if the E-brake is in working condition, it can still be applied in a situation where the main lines fail.

This was what my problem turned out to be. Most are freely offered on the net.

Haldex consists of close to 20% of our fleet. If it is the reach style, check the wiring that runs from the reach hangers to the car body of the trailer. What I've seen in cold weather is moisture gets into the Aluminum sensor mount and Freezes, cracking apart dropping the wheel speed sensor loose in the Brake assembly, breaking it's wires. Why the Lamp plays up. The trucks' electronics do not throw enough wattage to the system, the same problem with digital trailer light clusters, the dash indicator only showing that the unit flashers are working.
