ABS problem!

[Reaper]

Hey guys, my ABS went out and it's over my head! I need a GOOD Yamaha service center to take it to get fixed. Anybody know of one?

Have bike, will travel!

I understand where you're coming from. Of all the systems on this fine ride, the ABS system is the one that's been touched on the least. It must the the strong Black Magic generated under that right side panel. No one has demonstrated the necessary ju-ju for problem systems in this area.

My ABS, too, is non-functioning...at least for sure on the rear. I don't have cojones big enough to purposely induce a front-tire skid. I like living too much!

I'm hoping a soon-to-be-conducted major fluid service on my 04 may correct the issue. There are a couple of itty-bitty fluid passages in the ABS pump motor that could easily get plugged up from crap-filled DOT4, rendering the pump less than useless.

On my bike, my ABS warning light operates exactly like it's supposed to, assuming "normal" operation, but a stomp on the brake pedal locks the rear right up. No ABS action at all. As far as the bike's ABS ECU is concerned, the system is nominal. Everything is perfect....except it don't work! :blink:

Now I'm wondering if mine works? What is it that's telling you that it is not working, or how do you tell that it is working?

my 05 has abs when i bought it i tested it by using no front brake and steping hard on the rear while going at a good pace 30-40? i could feel it pulsing similar to a cars abs my 2cents.

1. Parking Lot

2. Speed

3. Stab the Rear Brake

4. Note Results

Repeat except #3 = Grab the Front Brake

Exactly what bshay and Ignacio said. Find you a nice, empty parking lot, drive up to about 20-25mph and grab a whole bunch of rear brake. If the tire locks and slides, your ABS is AWOL. If it works,you'll feel the ABS kick in, pulsating through the pedal, and you'll simply stop with little or no drama.

Trust me, if it's working, you'll know it. You'll feel the ABS pump pulsating through the brake pedal.

BTW, Ignacio is a whole lot braver than I am if he has, indeed, tested his front ABS. I'm too big a puss to try that! :blink:

So, in a nutshell, if the tire locks, the rear end slides, and you eat a plateful of asphalt, your ABS ain't working. :rofl:

(but seriously, be prepared for the rear end to slew around a bit IF the ABS fails and the tire locks up)

That's what running with a rear roadsmaht tire will do for you (aside from increased mileage). It validates and verifies the ABS functionality on every instance of rear brake application combined with semi- vigorous down shifting.

But, hey... maybe that's why yours doesn't work Howie.

Darksliders don't need no ABS.

Sorry John...that sucks and I hope it's a minor issue

Search for dealers near Southaven with their certifications shown...

the last one in TN shows promise

there's also another page of more choices (click "next")

hope this helps

Sorry, Fred....no cigar.

My ABS problem, documented HERE predates my journey to the Darkside by many, many months.

For controlled rear-wheel slides -- good posture is your friend (head and eyes up, sitting up straight, feet and hands at the controls).

Ignacio said: "Stab the rear brake." & "Grab the front brake." Those are the operative terms.

If the surface is level and the bike is straight, more-often-than-not a straight rear-wheel slide will result (w/o ABS). Note: if the rear wheel does slide sideways -- don't release the rear brake but keep it depressed 'till completely stopped.

Front tire skids are more critical (easier to fall down...) -- but, remember: if you release the front brake the tire will regain traction. So -- GRAB the front brake suddenly and if it skids (no ABS) release the lever immediately.

In that case, your bike *anticipated* the CT and it was protesting...you just didn't listen to it.

When I discovered my ABS was out I took it to a silver certified Yamaha dealer. They diagnosed that the hydraulic mechanism of the ABS was rusted open. $1200 to replace it. :dribble: Since I ride 2 up with the Mrs. I bit the bullet and had them replace it.

Thanks for all the replys. Tried this in the Albertsons parking lot and was susprised at how well the bike stayed under control while under hard rear breaking at speeds. After years of dirt bike riding, I have learned to stay away from applying any excess amount of front brake pressure, so I will give Ignacio :thumbsupsmileyanim: for his testing procedure.

HOLY CRAP!! Now that's a bite in the shorts! :dribble:

I test the abs on a hard packed dirt road -and ever since I read about the actuator piston rusting in it's bore from lack of use I usually exercise it on this dirt road, at least with the rear brake. Also good to keep fresh [moisture free] brake fluid in there. Side note: I have seen the abs unit for sale on Ebay somewhere for a lot less.

I hadn't heard about the HU rusting, I'll keep that in mind now. Yikes. And the f'ing thing isn't serviceable, you just have to replace it. I don't trust ebay with anything, much less something related to my personal health and safety. I'd much rather cough up the bucks for a known reliable unit.

My new SV-650 has ABS, but I've never been able to get it to fire because of the sticky tires, and I don't have any dirt roads for miles.

Believe me, I looked high and low for a cheaper replacement part. At the time there was none to be had. I found the part in a few places for the exact same price the dealer charged me for it. If I recall correctly the part was somewhere in the $975 range. There was also the labor charge for replacing the part and a charge for new brake fluid.

All things considered I am happy that I had it done. Had a car change lanes and then break hard in front of me when I had the Mrs. on the back. Felt the ABS kick in as I tromped the rear break. The Mrs. was never the wiser (read did not get nervous).

Found this on eBay:

2006 ABS Pump/motor

I should go grab this suckah!!

Make sure it is compatable with your 2004!
