I own a YR 2000 Vette and want to exercising ABS module - Is there a difference if I activate the ABS during braking or if I raise the back-end off the ground and hit the accelerator?

Thanks

If you just raise the rear and try to do this, you'll get all kinds of codes I think since the front wheel will not be reporting and rotation. Take it out on a rainy day is an OPEN area and play some.

I also have a 2000 and exercise during each oil change....when the rear end is up....works for me and never got a code from that.

Could you explain what exercising the ABS module does? Just curious.

Vetteman Jack - Exercising the the ABS module simply means you are making the ABS module kick-in and perform it intended function - Some people exercising the ABS module by stomping on the brakes, connecting the module to the battery, and raising rear-end and accelerating

There are some on this forum that believe it is very important to engage the ABS module to keep it 'healthy' and pump fresh brake fluid through the unit

Hope this helps

That is how you get a 6-pack?

This does not really change out the fluid but does exercise the pump and internal valves. You have to bleed thru the ABS unit to get new fluid in. Using a Tech 2 is the easy way to do it since it takes you through an automated bleed around all 4 calipers.

I've been doing it wrong? I just power slide the rear end out during cornering. That message pops up on the display. I guess we learn new stuff all the time?

Thanks - yes, this helps explain it.

So unless I ocassionally brake really hard my ABS never gets activated and this could possibly be a bad thing, do I have this right or not? Is this true of all cars with ABS? Thanks

Yes, not activating it is not as good as doing it. Kind of like using your brakes ensures they will most likely work when you need them.

It still does not flush out old brake fluid, just kind of mixes it up "some".

True for all ABS systems. I activate my wife's Lexus every time I rotate her tires.

I have the Tech 2 for the C5. I think the cost of the Tech 2 is about the cost of the dealer doing an automated bleed (once).
