2002 R1150GSA ABS2 fault

[daveg]

Hi Folks

I'm away touring at the moment on my newly acquired 52k mile GSA.
When I picked it up a couple of weeks ago I thought the ABS was very noisy when it was setting itself but didn't worry about it. Also it seemed to set at random on a trip when pulling away. Normally it's just on start up isn't it?

Over the past few days the ABS has been turning off with the lights alternately flashing. I've reset it a number of times by jumping 'the pin' in the diagnostics plug to earth and holding down the ABS button for 8 secs and this works but the fault comes back after a few miles.

Any ideas what it's most likely to be out of all the options?

Also, if I wanted to remove the ABS is likely to be made complicated because of the electronics? It's non-servo.

Any advice appreciated.

Cheers

David
PS the bike rides a treat

The fault could be anything from a dodgy wheel sensor, corrosion on a connector to the abs unit needing a clean up or refurb.
As its non servo abs there is no need to really remove the unit as the brakes will function as normal anyway. A bit of tape over the flashing abs lights on the dash until you get home will stop them annoying you.
Your not still on the original rubber brakes lines are you (assuming the adv didn't have braided as standard)?

The ABS will set (clunk-click noise) when you first move off and again after an interval of ... kms, it will set again as you move off. The usual issue is that the battery is not able to keep the required voltage up when starting the bike. This will show up if the abs does not make noise when you first move off after starting the bike. If this is so, the lights will keep flashing. You can get up a bit of speed, pull clutch, switch key off, switch key on, bump start without stopping, then stop, then move off and if it sets, then it points to weak battery on starting.. Try that and let us know. The ABS is well worth having, and does not give much trouble if battery is strong.
Steptoe showed a pictur of how to clean a filter in the unit if needed, simple job, I have never done it, so far no need.

Pull the Blue relay in the fusebox out that will stop the flashing lights

Basically you need the code read but recently I said to some one to clean their abs rings if they were rusty looking and they did and it cured their fault

I have had quite a few visiting this last for diagnosis which turned out to be Rear ABS sensors giving up the Ghost

Laurence I am nearly sure that filter cleaning thing was on the Servo ABS units ,

I think you're right, it was for servo only.

Hi,

yep, filter is servo issue, so not relevant..

Try to see if the problem comes after starting from cold when battery load will be highest.

Thanks for the responses guys. I'm in Bantry (Ireland) at the moment and spending the week wiggling around the coast on the smallest roads possible it seems! I don't really want the ABS while I'm on this trip but I'd like to stop the flashing so I'll try pulling the blue relay in the morning. When I get home I'll start cleaning sensors etc.

The battery is a fully charged Odyssey and I've got braided brake lines. The fault starts up after I've been riding a while.

Was one of the latter

Check batt voltage then discs/sensors. I was usefully explained by a wiser owl than me that the sensor check doesn't depend on the distance from the disc, meaning you can fault diagnose the sensors just by plugging in a working spare and not have to mount it to the hub

You can build a little test LED to blink a sequence which will correspond to what the error is. I built one and it pointed towards a rear sensor fault. After cleaning the sensor and where it connected to the loom it went away and is still going strong.

Well, I managed to have a look at the rear sensor and it not only has a damaged wire where it's worn against a guide but the sensor itself is possibly damaged (worn on the end) and the connector looks a bit corroded as well so plenty to attack when I'm home.

In the meantime I've opted for the black tape over the lights fix...

Thanks for all the help.
