After reading about the issues with stuck fuel pumps and old fuel I
would like to pass
along some experience I have had with freeing up a stuck fuel pump
Many times the varnish will keep the pump from running. The problem
is pulling too many amps
and kicking out the fuse setting on the computer or on older/other
brands blowing the fuse.

1.After removing the pump fill the pump with your favorite brand of
penetrant oil and let it soak for
and hour or so.(inlet turned up.)

2. Make up a jumper cable system of sorts. I use bolted connection at
the pump and
small alligator clips on the other end.

3. Hook the pump connections first. Then the clips at the battery
next. If the pump runs, then submerge
it in a fluid such a varsol or something similar and let it circulate
and flush out the old varnish.
Only leave the clips on the battery for a few seconds if the pump does
not spin. Reverse the leads
at the battery and try again. This method seems to allow full amp to
the pumps. Reversing the leads
will try to spin the pumps first one direction and then the other.
Once it begins to spin and pump
place it in a vat or bucket to flush it out. It may take 10-15
(bumps) to free the pump.

Of course if the pump has physical/electrical damage none of this
will help. If it is just
the varnish sticking and keeping it from turning it may save you a
pump purchase.
Good Luck.
As always... safety, pick a liquid that will not cause sparks, fire
etc. :)

Hi Ducati,

Thanks for this very valuable "How To" info, you just made me dig up
the old pump that came out of the HP2.....;-)

Hi All,

I just started have a front brake problem on my 2003 R1150RT (Twin Spark
with ABS and 50K miles). The ABS lights were flashing and front brake would
not engage......rear brake made all work fine. I hooked up the GS911 and my
worst fears were confirmed when I got the code 17163 "Front ABS motor
defective".

Before I go and spend $2500 for a new ABS unit, is there anything else that
I should check out that could possibly give me the same code or I should I
just resolve myself to spend the $$ for a new unit.

Thanks for any advice,

Joel Watson

Hi Joel. I would find it hard to justify spending that amount of money. The repair cost versus bike value is way out of proportion. Would you consider removing the abs altogether?

Hello.
Bleed the brakes with new brakefluid.
Go driving the bike, use the brakes very hard, a several times.
Do it agin...
If you are lucky, the ABS will start working.

Here are some options I found (cut and pasted), if it doesn't turn out to be
something a bit less expensive (like a loose connection, for example):

"If you don't mind a bike with no ABS, a few have removed the ABS module and
purchased new brake lines etc to have conventional brakes. This would be a
DIY project as no BMW dealer will likely touch it.

Another option is buying a used IABS module from a wrecked bike. Try
beemerboneyard as one source for used parts.

Last thing for the really fearless, is to take apart the IABS module and try
and repair it. Sometimes the pressure sensors stop working in the module.
There was a guy on Adventure Rider that did this and it worked for him.

Unfortunately, no easy solutions for you.

Good Luck!"

If/When this happens to me on my R1200GS I will have a go at fixing it and
then, if that failed, do my best to remove the ABS (and get the ECU
reprogrammed to 'tell' it that it is a non ABS bike). The only thing ABS
has ever done for me is cost money. When I fell off the bike in the ice
last winter (no big deal, BTW) it was useless.

Sorry, not strictly on topic, but I hope this helps.

David

Sir,

What is the status of the battery? A battery going sour can lead to all kinds of ABS misbehavior, also strange error messages.

Good luck,
Caspar.

Hi Joel

If you contact Motorworks in the UK they will advise on removing the ABS and
can also provide all the parts required. Hope this helps.

If the ABS unit is bad and it is indeed the motor has failed and not the
electronics why don't you take it a part and verify the failure. If it is
the brushes they might be able to be replaced. If it is the commutator a
small motor shop might be able to rebuild it. There are pictures on the web
showing the internals of the ABS. It will not be a easy job but, might be
worth the effort. Lets us know what you find.

Mike,

This is only a problem if the bike has integral ABS (iABS).

A bike with ABS 2 has normal master brake cylinders and can pretty easily be
modified to one without ABS. This is NOT true for a bike with iABS, since
the brake pressure is delivered by the ABS pump and not by the master brake
cylinders.

You need to modify the brake lines etc., and of course knowing what you are
doing.

There are some interesting descriptions on the internet.

For disassembling the ABS 2 unit:

You may be able to have the ABS unit repaired. Try BBA-reman or Module
Masters. I know that BBA does numerous
motorcycle ABS units for sure. Check with them and see.

Thanks for all the replies!! I did check the battery and it is strong.
Applying the front brake does absolutely nothing......applying rear brake
stops as usual. Servo motor seems to run constantly with no effect when
front brake is applied. Will bleed the servo unit and check connections
first and then pursue other suggested options. Thanks again for all the
advice. We will keep you posted on outcome.

Just my uneducated 2c. you say "Applying the front brake does absolutely
nothing...". I would have expected some action even with the ignition
off! To me, this would suggest something outside of the ABS, such as air
in the front circuit lines.

HTH,

Dave.

This is a clue.  Does the brake light behave normally with both the front lever and and the foot pedal? (It's controlled by the ABS unit on the 1150 series.)  If not, this may not be a ABS unit issue at all, rather a switch or wiring issue keeping the ABS unit from initializing.
 
If the brake light does work normally, then the next most likely thing is a stuck piston in the ABS unit. With some skill it is possible to disassemble it an clean up any corrosion on the piston (common) and with luck get it working again.

David, I'd agree, maybe it has a faulty front brake master cylinder.

Had a similar situation with an 02 RT.  Did a complete brake fluid flush, reset code and problem went away and has not returned for the last 30K.  Worth a try, if you do the work yourself, only out the cost of a liter of fluid.

If the piston inside the front master cylinder is sticking, the brake lever will not release completely, which makes the brake switch stay on constantly.  If the brake switch is read as "on" when you start the bike, the ABS will not go through its complete check procedure and the ABS will remain off.

Do this:  (1) make sure the battery is completely charged, (2) push the front brake lever all the way forward (completely released), (3) start the bike, making sure that there is no pressure on the front brake lever, and (4) give the ABS about 15 seconds or so to complete its cycle check.  Then test drive the bike.  If the ABS system is still not functioning, then the problem is something other than the front brake master cylinder piston.

If it turns out that the front master cylinder piston is sticking, you can buy a replacement piston here:

Unfortunately after checking all the possibilities, the problem turn out to be a bad ABS unit.  It’s my friend bike and he has the dealer replacing……for a substantial charge.
