ABS light on the traioler & DOT

Yes a warning ticket. Not OOS. If when you turn the key on, and hear it clicking 4 times, it’s working. If not it’s not working. Turn key on off on off on- then count the flashes on the trailer light. Number of flashes corresponds with location of the problem. If the light only comes on, stays on without blinking, the systems not getting power. If so, be careful, might lock up in rain, or sudden stops. Mechanic is a mechanic in job description only. He should know enough to fix the light, it’s fairly simple. Even for a shade tree like myself.

 

Unplug the ABS light on the trailer.

 

This is also a violation if thr light doesnt flash when turning the key on . most officers check for this as well

 

Take it to a shop that can actually tell you what’s wrong, many shops are clueless to how to figure an abs problem.

 

That’s a for sure ticket if they check. Leave the light hooked up and you might get lucky and the abs system might work.

 

I once passed a level one inspection with a trailer ABS light on. This after having taken it to the shop and being told as you were.

I'll bet you have a dirty sensor.

 

Or a bad wheel bearing. If all mechanical is good, it's not a huge deal. Not sure why ABS repairs are so difficult for some mechanics, especially on trailers. The system is so simple.

 

The initial simple check is to make sure your plug has proper power going to it, that it's working correctly. I'm having this problem with my truck, around 60% of the trailers I haul I'm getting a trailer ABS light, yes, a portion of them are junkers, but it's doing it with our privately owned equipment too. Boss checked it and cleaned out corrosion at last PM, when he get's back from vacation I think we're going to put a new end on it.

 

thats actually a higher violation then the light being on to begin with…
