i lowsided my fjr and the engine light is on. what could trigger that?

[fjrandmore]

after 30k miles total on both my fjrs. i finally went down on my 2006. now the engine light is on and the speedo dosent work. there are no leaks and it just has right side saddle bag and mirror scrapes. what could make the engine light and speedo NOT work. by the way. i rode the bike home which was about 100 miles with no problems. thanks for any help. ps: the abs light came on as well but, that was happening after a rear tire change about a week before the crash. there is some kind of switch hanging down by the back brake. the switch seems to run along the rear brake line.

Check the circled part in this pic:

That is your ABS sensor and would explain the ABS light, who the heck installed the tire?

In the FSM, they make a big deal about not letting the ABS sensor touch any metal when you take it out. If "fjrandmore" has had his out and dangling around for a week, is it toast? What happens when it touches metal?

well. that was the switch that was hanging out. the shop (which has changed tires on multilple bikes i have owend with no problem) left a bolt loose and it backed out. do i have to replace the switch. there doesnt seem to be any damage to it? by the way. thanks for the fast response and help.

Well there are two responses to that question: one would be well thought out, and the other one I will give - install it properly and see if it works. Actually you might want the dealer to install it, if it doesn't work it should be on them.

That also explains the speedo not working. The GenIIs use the rear ABS sensor as the speedometer signal.

As for "touching metal", I'm pretty sure it's mechanical shock that would damage the magnetic material the sensor is made of. I agree with v65, if it works, don't worry.

I would advise checking its wire for damage, particularly near its rear support; its insulation may be damaged.

So how about the check engine light?

I know I've read elsewhere on this forum that the check engine light comes on after a tip over. It has to do with diagnostic error code 30. But I have no personal experience--knock on wood.

 

[Herkypilot]

I've heard of the error code 30 on the tip over also, but I didn't get it on my light get-off this past spring.

From the bin-o-facts:

Diagnostic Mode:

(Appears to be the same for '03 - '05)

To enter Diagnostic Mode: Have the key turned off (kill switch on) and press the Select and Reset together. Turn the key to on and hold the buttons for about 8 seconds. A screen will apear that reads "d1 AG". release the buttons.

(so far, same as prior models)

Use the "SELECT" select "Co" adjustment or the diagnostic mode "d1 AG". Press Select and Reset for 2 seconds. "d:01" should appear on the clock if you did everything right.

Press "SELECT" for the next code, Press "RESET" for the previous code.

Codes go from d:01 to d:70 -- go buy a manual for the codes.

Note: Lean Angle Sensor (Overturned Motorcycle) Fault code: 30

Scroll through the diagnostic codes to:

61 (the history of fault codes). If you see a 0 at the bottom right then there are no trouble codes. However if you see a number 30 that is the code for an over turned motorcycle. If you have the code 30 and want to erase it. Press the select button and go to number 62 (erase history code). Then turn the kill switch off, then back on again. This will erase this and any other codes stored in the memory. Then turn the key off to go back to normal operations. If you have any more codes I suggest you order the big book from FJR Goodies to problem solve or take it to your dealer.

Thanks all! I just started having some electrical weirdness after my club buddies and I changed my tires. This post helped me fix a couple of them. The rear ABS sensor had started to back out causing my ABS light to come on and my speedometer to quit working. Thanks again. Great forum!

I'm kind of wondering why you're removing the ABS sensor from it's housing when changing tires? Whenever I change the rear the whole housing can be taken off the wheel without removing the sensor from it.

Maybe I'm doing it wrong, but I change tires 2-3 times a year and my ABS works just fine.

+1 When I change the rear tire; I just remove the whole assembly and let it hang (or lay it across the top of the swingarm)...protecting it with a sandwich bag. I've never removed just the sensor bit.
