ABS cycle

[lankywhale]

Hi

 

In November I bought a 2006 6 gen ABS with 15,000 miles (Wales, UK).

 

I wanted to do some preventative maintenance so I upgraded the reg/rec (FH020AA) and associated wiring. I also added a gear indicator and a few other bits. Everything seemed to work great so I put the bike back together and took it for a spin. I noticed once over 6mph the abs light would flash.

 

Hmm, didnt do that before!

 

Long story short, I fitted a used abs module and it no longer flashes. Great success! 

 

Anyway, what I wanted to ask was about the cycle of the abs light. What mine did before was:

Key on, abs light on, over 6mph abs light off. Anytime I go below 6mph it would come on again and stay on. Set off over 6mph it would go off again.

 

What it does now is key on, abs light on, over 6mph abs light off. If I come to a stop it stays off. If I key off, then key on, the light comes on and then goes off over the 6mph etc.

 

In my head the latter makes more sense. Just come on once and then stay off for the rest of the ride. I've just watched some YouTube videos of riders with helmet cams riding vfrs with abs and all their abs lights also seem to stay off when they stop in traffic. So I'm wondering if I unknowingly bought the bike with an abs fault. 

 

I just want to make sure I've definitely fixed it and it's functioning the same as everyone else's.

 

Thanks in advance!

Your last statement sounds like it's returned to normal ops.

The ABS system is critical on good battery voltage, so just check the state of your battery and clean tight battery terminals, any doubts about the battery, have it load checked.

Have you downloaded the Service Manual? If not you can download it from this forum. Section 16 ABS tells you all about it. Like the ECM the ABS has its own diagnostic error codes.

Good luck hope this helps.

Hi, thanks for the response. Thats good news then! I replaced the battery as the one it came with was on its way out. I followed the service manual. Went through every step regarding abs because I wasn't getting fault codes. Determined it was the module. 

 

Thanks very much!

Think of the ABS light as the system doing a self-test on startup. It shouldn't need to do that self-test every time you go below 6mph. Thus, the sequence in bold, above, is correct.

 

Sounds like you've sorted it out, well done!
