Flashing ABS light

[RadioHowie]

Just wanted y'all to know before you entered a battle of wits unarmed, "Search" came up with this:

https://www.fjrforum.com/forum//index.php?s...111&hl=flashing

which was NO help.

Could someone elaborate on the cause, diagnosis, and possible cure of a flashing ABS warning light.

Does it mean my ABS is inactive when the light flashes?

BTW, an ignition recycle shuts the light off.

Well, I am unarmed since I don't have an ABS FJR, but............

If the abs light is blinking, it should mean that your ABS system is indeed deactivated. Brakes will work as normal non-abs brakes, so you still have full braking power, just not the anti-lock part of the equation.

Have any of you that have experienced this problem gone into diagnostic mode to check for any error codes? Does anyone know if there should be error codes?

Good luck.

When is it flashing? I know when I place my bike on it center stand and then start it up and place in gear it will flash, so that should mean it is not functioning properly.

If you are riding when this happens, you should take to dealer to have them trouble shoot unless someone knows, the breaks will still work you'should just be able to lock them up.

Yo Howie - don't you have an 05 FJR? In which case, don't you have a service manual?

Usually, a dose of IMODIUM® will cure your Aggravated Bowel Syndrome. Dunno why your light is flashing on the bike, though...

Yo Howie - don't you have an 05 FJR? In which case, don't you have a service manual?

Nope on the '05...mine's an '04 and nope on the Service Manual.

Although, if anyone has a service manual in digital form, i.e., PDF, I'd be glad to host it for the benefit of the community.

Ok, some of you owe me beers in Reno. Remember, I don't even have an ABS. ABS? We don't need no stinking ABS!

So I just pulled the celophane off my my service manual ABS supplement that I have had for 21/2 years now, and I have learned a couple things.

FLASHING ABS LIGHT - According to the service manual, ABS function of the brakes is still working, it's just that the, "ECU (ABS) input has unstable factors." Whatever that means. And for details, one needs to refer to troubleshooting, which as far as I can tell requires a special diagnostic test coupler adapter.

So if your light is flashing only, ABS should be working still. Personally, I would test it by trying to lock the rear brake just to make sure.

If the ABS function of the brakes are not working, then the ABS warning light is supposed to light solid. No blinking.

Just as an FYI, the ABS system has it's own seperate ECU. So it seems that the FJR's normal diagnostic mode won't work here.

And why not?

Ack!!!! Bad form. Any PDF copy of the service manual is a pirated copy.

So we still don't don't what's causing it?

'cause I'm a cheap ******* who would rather pirate one than pay for one (see below)

And your point is.....?

 

[SkooterG]

So we still don't don't what's causing it?

We? Your too cheap to buy a $40 service manual? We?

I am getting closer to that. But since you are more than likely too cheap to buy that test coupler adapter, you will never know. Unless you take it to the dealer and pay big $$$ for him to tell you.



And another thing. You have not helped out your own cause here by giving next to zero information on when, or how often this flashing light comes on.

Details?

Can you feel the love in the room, brothers and sisters?

To be specific, I've noticed the light flashing when I've pulled into the garage after my home commute two days out of five. I didn't notice when the light came on during the previous 40+ miles, and probably wouldn't have noticed 'til I was parked in the darker garage and saw it flashing. I do corner/brake/accelerate fairly aggresively in almost all driving conditions, so it may be an issue of ham-fistedness.

Not sure of the reasoning involved as to why those of us who have bought a manual should advise/subsidise those who won't/refuse to. So, +1 on Das Skootage. (not that it would help without the SuperYami© decoder ring)

So based on YOUR reasoning, we should just shut down this section of the forum?

Okay wit me. No more arguments about fork braces and steering dampers :yahoo:

Gee.......ya think?

According to the service manual - You do realize I am charging $.10 a letter for all posts pertaining to this assistance, don't you?

Where was I? Oh yes.

According to the service manual, the following conditions can lead to a flashing ABS warning light:

1) Rear wheel rotated while on centerstand.

2) The rear wheel raced.

3) The motorcycle was ridden on the rear wheel with the front wheel elevated.

4) The motorcycle was ridden on extremely uneven roads continuously.

5) The brake switch is defective or improperly adjusted.

Additionally, "The ECU (ABS) may stop the ABS operation if it is exposed to extremely strong electromagnetic waves(my italics) or static electricity."

Don't you work at a radio station? Or, wait, you own it don't you? In which case you don't do any work at all.

Not sure of the reasoning involved as to why those of us who have bought a manual should advise/subsidise those who haven't.

What the radman said. Damn! There I go again. Somebody spank me!

 

[radman]

I changed the wording slightly-haven't to won't/refuse to. More accurately states my opinion.

 

[JimLor]

BATTLE!!!!!!!!!! :dwarf:

 

[Fabone]

Scooter pretty much covered it.

Most always the light is triggered when one wheel comes off the ground, when engine is running and in gear. If you fly over railroad tracks, rough road and potholes, it will set off the light. Does the same thing when bike is on center stand running in gear. It will send a message to the ECU that something is out of sync.

Sometimes the sensor is dirty, but most times not. Turning off the key and then on, will recycle the system, same as rebooting your PC.

May better state your opinion, but doesn't change the fact that you're essentially telling anyone who posts a question here "**** off and go buy a service manual."

Not to mention your omniscience about poster's plans/abilities/motives for buying or not buying service manuals.

"Haven't" was actually a better choice of words from your previously unedited post, since it doesn't preclude a choice to purchase a manual at a future date while your opinion that someone"won't/refuse to" purchase a manual fairly closes that door, doesn't it?

And we all know how unopinionated you are.

What the radman said.

Glad to see you and the radguy are together on this.

Damn! There I go again. Somebody spank me!

 

[radman]

My statement was based on this-

'cause I'm a cheap ******* who would rather pirate one than pay for one (see below)

So there. Infinite.

Howie-

You're welcome.
