Front Abs connector broken

Hi all,

I had abs light on last time I was riding and diagnosed the error codes as per the manual with 43 being the error code.

Later, I checked and found that the connector in front, near the handle bars had one wire broken off. It took me a while to take out the connector and also had to break the second wire from which the connector was dangling so that I could attempt repairing it.

The issue is that I can't find a way to release the pre inserted wires from the connector to put new wires in. Any help will be highly appreciated.

I also note that another rider has this issue and was discussed extensively on the forum however no conclusion was met as to how to fix it. Please see attached pictures that will shed more light on the issue.

Regards

They have release clips from the pin/connector side. They make this small flat bladed tools to release the little plastic latch that holds the pins into the connector. I have several small mini pick and hooks that I typically use for these.
Since these are water proofed with those orange rubber wire seals they will be tough to remove. They have several ridges on them like christmas tree push pins to grab and seal water/elements out.

When I was a mechanic use to deal with these all the time on ABS and SRS wiring.

Thanks for your reply.

I could get the white housing out from the connector side and I think I can slide out the orange rubber seals. After that, I'll inspect it closely to see if I can release the latches with something small with a flat head.

Is there a replacement connector that I could purchase, in case I can't release the stuck wires?

Thanks

Thanks for the reply, yes I did however wasn't sure if that was the correct part. I have ordered them now. Meanwhile I will try to salvage the enlisting connector to see if I can fix it.

It's also possible more than one part exists across the years, like with the diagnostics connectors... :-(

There was a recall on some Ninja 400s for the front ABS harness, and Kawasaki will replace it if yours is part of the recall.

There was a recall
Oh, right!!! I elected not to have mine replaced because I'd already used marine grade heat shrink on mine to protect them -- but if they ever break, I'll bring it in!

Thanks, I looked into that and unfortunately no recalls are available.
Weird, and my recall (technically I think it was a "safety bulletin", rather than a "recall"?) actually disappeared... Maybe ask a dealer if you have not already.

Hi All,

Thanks for your input. I did order the parts however I believe it won't be necessary as I was able to salvage the old connector, though I won't call this as an elegant solution. I'll attach the pictures for reference, as it may help someone out in the future.

1. I tried unlatching the connectors from the black housing, using the diagram provided in one of the older threads, but wasn't unable to.

2. Since I had already ordered new connector, I decided to play with the one I had and used a dremel tool with a cylindrical sandpaper to remove the sheathing from where the wires had broken. This exposed almost half inch of wires. I was careful enough to not damage the wires as it was my only chance. Then I unsheathed the wires.

3. Next step was using extension wires and soldering it to the exposed wire from the connector. Then I used heat shrinks to protect the ends and used electrical tape to provide additional rigidity.

4. On the other end of the extension wire I used a female - female connector that was later crimped to secure the wire. This was also heat shrunk. See pic attached.

5. This entire assembly was then attached to the bike's exposed wire with a similar method as above.

6. Tested the bike, and tried the breaks, the abs kicks in and the light was no longer on.


In hindsight, the original assembly is asking for trouble as the length of wire is extremely short, the wire ends are not protected and the entire assembly moves with handlebars. Kawasaki should probably do a better job with the assembly.

Thanks for your time.

Nice with the heat shrink -- thanks for sharing the steps you took!

Hopefully when you pull at the wires, it is well restrained and there is no tendency for anything to bend near the solder joint.

When your new connector arrives, it would be great if you can confirm it is a match for the original.

Thanks again!

Payne21, I’m impressed. Hoping not to have to deal with this connection but your information could help many of us in the future.

The biggest issue with the DIY fix is that you've removed the waterproofing for back of the connector. Since it's a sealed connector, any water that happens to get in would be more likely to pool there. I'd definitely add some silicone or similar to where you soldered on the extension wires to keep water out. You'll probably want to make sure the other end of the extension is sealed well too.

Wheel speed sensor recall may be related to the issues we've seen with the wires breaking at this connector.

You are welcome. Dang it I forgot about some that have that "extra" latching system to hold the wires and terminals in place. Some are white, or yellow and I think, and this is me just guessing it has to with keeping the pins even more secure to avoid movement and potential increase/decrease in resistance and flow of currents. Especially were ABS and SRS are so suseptiable to change in resistance and flow of voltage as a very slight increase or decrease can throw and error and a ABS or SRS light on the dash.

I more than likely subconsciously blocked out those memories because I always hated wiring, electrical issues, etc. and always got stuck with them too.
I now think because I am so OCD and thorough with things and the fact that unless I triple check it and make sure its as right as it could ever be or loose sleep over it, they always gave me that crap.

Little story time for you......
Right before I got out of mechanic work and went the IT route instead I was the one certified technician on the new VW Touareg and Phaeton for the dealership I worked at. I was part of the discovery on why VW was buying back 1 in every 3 Touraeg's they sold, which was due to all the electricals issues which turned out to mostly be centered around SRS, airbag wiring within the car harness faulty or failing. I cannot tell you how many wires I fixed, repaired, etc. in order to isolate and determine the root cause. I fixed and rebuilt connectors and etc. Also the problem with doing that is, if you repair, at least at the time, wiring for SRS it is not safe to return to a consumer. If it was 10x better than anything original. Becomes a legal liability in the event that a airbag or some safety system does not deploy or do its job. So once we identified the same issue and point of failures across 5 different vehicles, the fix was to replace the entire interior harness of the vehicle (all one piece, handmade in a factory that took 1 month to make each one)

I got a job working at Dell during this one month time frame going into IT, while I had 2 new Touraeg's completely tore down interior wise; this was seats, carpet, headliner. all trim, all center consoles, dash, etc. completely out of the vehicle waiting for the new harness to go into the vehicle. I was really hoping it would show up in time for me to put both of them back together, but the 2x harnesses were delayed another 2 weeks and that Friday before the week they showed up was my last day there.
The new apprentice VW mechanic late teens kid got stuck having to put all that back together as his first big job working on a VW. Lol. :ROFLMAO: 😥

^ This. Unless you never wash the bike or fortunate enough to never get stuck in the rain even taking black RTV sealant (ultra black permatex works good enough) and just glob it on the entire back half of the connector, wiring, crimped wires, etc. and then sculpt it so its not just a big blob, let it set up and dry good to waterproof all of that, it will end up what InvisiBill said.

I agree, and I am fully aware of it. My plan was to test the connectors out before I seal it.

The other issue I have to take care of is routing the wires efficiently, given I extended its length and as of now it just gets bundled.

Lol, thats funny and sad at the same time.

I'll make sure I seal the connectors, thanks for reinforcing the idea.
