Freightliner “Check Tag”

[USMCRET]

I’m new to the world of tags and FL chassis so I’m just learning the ropes.

As I was leaving a fuel station today, I ran over a belt of some sort that flailed against the side of the MH a couple of times. I stopped and got out to look. There was a long broken fan belt of sorts laying behind the coach. I’m certain it was not from my coach.

As I was making the turn to get back on the interstate, I received a “Check tag” warning on the dash. I pulled over and cycled the tag switch through it’s positions and the light went out.

As I approached stop and go traffic, I noticed that each time I came to a stop, the tag would dump air. Not right obviously.

Anyone have any experience with a similar situation?

I left this morning to take my coach to the shop and the previous day’s problem had healed itself. These things are weird.

Your tag switch has three positions. Pushing on the front of the switch (AUTO) the tag dumps automatically at low speeds so that when you turn a corner, the weight is taken off the tag to prevent unnecessary wear.

The middle position on the switch is OFF. The tag dump is off and does nothing.

The third position is a manual tag dump (MANUAL DUMP). If you push it once, it will dump the tag manually and the dash will light up, saying tagged dumped. If you leave it in that position, as you drive forward and reach a certain speed, the tag airs up. When you slow down to stop, the tag dumps again and you get the dash light. To get it out of manual tag dump, push the back of the button again, or push the front of the button and move it to Auto.

Once you shut down the coach, it defaults to the middle position of off. That's most likely why you didn't see it the next day. You'll also get a tag LOW AIR alarm when the coach is airing up, until the tanks are full and the tag airs up.

Thanks for that explanation, Don. Makes sense.
