When I roll on the throttle to the stop..I get no light.
Is my cable to tight or a micro switch is bad?
I looked but I can't find a answer.


This procedure must be done exactly as follows while you monitor the "SET" light on the instrument cluster:

1) With the ignition switch OFF, switch on the cruise control. Press and hold the cruise control switch to the SET position and switch on the ignition switch (LIGHT).

2) Release the SET button (LIGHT GOES OFF), move the switch to the RESET position (LIGHT).

3) Release the button (LIGHT OFF), switch OFF the cruise control switch (LIGHT).

4) Switch the cruise control switch back on (LIGHT OFF).

5) Rotate the throttle against the throttle stop (LIGHT), release the throttle (LIGHT OFF).

6) Pull the clutch lever (LIGHT), release the clutch lever (LIGHT OFF).

7) Pull the front brake lever (LIGHT), release the lever (LIGHT OFF).

8) Push the foot brake pedal (LIGHT ON), hold for 5 seconds (LIGHT OFF), release foot brake pedal (LIGHT ON).

9) Rotate the rear wheel (LIGHT SHOULD GO OFF/ON).

10) Switch off the ignition.


This method worked on my '99 and works on the '02.

Woof!

Try loosening up the closer cable adjustment up at the grip. That would be the inboard one. If that does not work pull the tupperware off the left side and look at cable routing. You should be able to roll the throttle "off" a small amount past the "at rest" position.

I'll do it now!
Well maybe not pull the tupperware.

I think I remember that if step 6 or 7 switches are stuck they can trigger a fault at step 5. This is because each step is a cut out signal. The test is set to check "proper" operation of each of those switches and not necessary to trouble shoot. So if you get no joy on the cable have some one rotate the throttle while you listen right at the tip over bar - you may be able to hear the switch "click". Do like wise at the clutch and brake area, listen for the clicks and they should occur some distance away from the slack point on the control.

Yep..no joy.
I tried 6 before 5 and no luck either.
Tried them all and nothing after 4..all works fine till 5.
Which side should I listen at?

I'll have the wife help me!

The microswitch is right in front of the injectors. You should hear it click.

To really understand how to troubleshoot the cruise-control, I suggest that you read the message in the link below:
http://www.bmwlt.com/forums/showthread.php?t=61130

It contains a link to a Video tutorial on YouTube, AND also a PDF (acrobat) file that you can print and use when you work around the bike.

I have attached to this message, a new "improved version" of the PDF file previously published on this site. The new version has 2 additional notes after the diagnostic steps (one related to the wheel-speed-sensor, another related to the brake pedal check).

One of the difficulty lies with the fact that the Throttle micro-switch and the clutch-lever micro-switch are on the same signal wire - thus when any of those 2 are not working correctly (stuck in the "clicked" position), the diagnostic will fail at the throttle step. As shown in the video, you need to pay VERY CLOSE attention to WHEN and HOW they click based on the lever movement (or throttle movement) - you need a quiet environment to do this.
