Video on Honda/Acura ABS unit repair/replacement

[Its me]

I have noticed many ABS trouble code lights activated on mid 90’s Hondas/Acuras. When working on them I hear the same story. The owner says, “I know the ABS is bad, but the dealership wants $1400-1700 for a new module and another $500 to install” (paraphrasing here). And since the Brakes are now just “regular brakes” they say that they will live with it.

While working on an Acura recently which had a persistant ABS light on, I pulled the codes and discovered that based up on the codes it appeared that the only thing that was bad on the ABS module was the Accumulator. After reading more, I also read about problems codes being fixed with just a gasket on the accumulator. It appears the whole ABS module has to be removed to get at the bottom of the module to remove the two bolts that hold the Accumulator on.
It appears that these accumulators go bad when the inner diaphram ruptures (they are gas charged as well)…. I do remember replacing accumulators in the GM Powermaster Brake system (remember those, they put them on Buick Grand Nationals and select Station Wagons)… Fortunately that accumulator just screwed on and off, but was very pricey at over $250 (and that was a while ago)…

Looking up the parts, it appears that an accumulator can be bought for around $370 and the pump (the other thing that goes bad) is around $450.

What I would like to ask if possible is a video of the removal of the unit (easy I know) and then replacement of the accumulator and or pump. Then, after re-installation, the proper procedure for how to bleed the the ABS module (I understand the solenoids have to be activated for this to be bled properly).

If anything, just an explanation of the proper procedure to bleed the ABS module would be of great help…

Thanks,

Karl!

It depends on the system. The older systems had replaceable parts but the newer ones don’t. There’s also a procedure to help the solenoids reset themselves. Thing is, I haven’t seen one of those vehicles in for a long time. In order to make the video I’d need a vehicle do do that stuff with. As for bleeding the system that might present a problem also. The only tool I’ve ever used for that was the one provided by Acura at the dealer. I no longer have access to that tool so I’d have to explore other means.

Thanks for your suggestion. If the opportunity comes up, I’ll be happy to make a video for you.
