You sure can take it in for just the TSB. I am
What they mean is that it is required to be done by the dealer if the car is in the shop for any reason, but they will not notify owners. They are also required to apply the TSB to inventory. You can bring it in just for the TSB.I'm confused. Is a tsb done for free but only if you have your car in for some other service? I can't just take it in for this?
Eh...it's a PITA going to the dealer for serviceHad my car in the Mavis Tire shop around the corner from my office for a front end alignment and tire rotation. So I just had them change the fluid to DOT 4 while it was in. Mine has 45k miles, they said the fluid was starting to get dirty and should have been changed soon anyway. I'll pay 70 bucks not to have to hassle with dropping it at the dealer

Interesting. So they have the software and interface to actuate the ABS module after a fluid swap?
That would be the "fancy" way of doing it. I walked back in as they were finishing up the last corner. They did have a machine hooked up to fully bleed the lines then they took it for a test drive around the block to verify all was well.
How do you think cars were worked on before all these fancy computersI'd wager dealers do the EXACT same thing.
Looked like this thing: How to operate a Wynn's Brake Flush Machine - YouTube
I'd wager the Hyundai dealership does it the fancy way by commanding the abs module to run the pump and open the normally closed valves so that all of the old fluid gets exchanged.
FYI, Mavis Tire Shop could do the same procedure by using the proper aftermarket scanner. The Wynn's brake flush machine does not open the normally closed valves, so old fluid does not get fully flushed out, leaving a mix of 2 different fluid types, generally not recommended.
Have you actually read the full TSB procedures? I did and it's not how you describe. Otherwise I'd be doing it myself. I'll be taking mine in to get it done properley.
Not worth the hassle and possible warrenty issues later down the road.
That's actually totally incorrect. The valves in any ABS module are normally open. The ABS module does not interfere with braking unless the sensors detect differential wheel speed. Only then will the ABS module pulse/close the valves to prevent wheel lock. Thus if you flush/bleed a brake system starting at the reservoir/master-cylinder, it would flush all the fluid out of the ABS module on the way to the individual wheels.
what model years does this apply to ?
2012 Rspec ?
