I think I might have a couple issues going on, but the main one that's super odd is when I turn the key off, even pulling it out of ignition, the display flashes for a second but then stays on. If I hit the engine kill switch it turns off the display.  But I'm not sure everything has been fully turned off, there seems to be a phantom draw because it does seem to kill the battery if left for a week. I figured the issue was a bad ignition switch, so I replaced it. But still the same issue.  I have run through all the fuse I can fine. Replaced all the relays... Not sure where to go from here. Could the engine kill switch be bad?  Never used it, just always left it on because I always found it kind of pointless.

I'm also getting a 0118 code, which from what I can tell is a coolant temperature sensor. But that maybe seem like a separate issue.  Figured I mention it incase it was some how relevant.

It's like an AUX relay coil is being back-fed through it's load circuit. Has there been any additional electrical accessories installed like lights, speakers, radio..ect?

[scottcahill07]

No, no electrical mods or additions have been added. Everything is stock as far as that goes.

Ok. Now..when you kill it with the kill switch after turning the key off, what happens after it stops and you switch the kill switch back on?

So when I turn the key off, the display dims a little. Turn off the kill switch, the display turns off. Turn the kill switch back on, the display turn back on.  This is all while the key is in the off position.

Wow..well..I'm going to say there is a problem with the harness somewhere or there is a chassis ground off...or...one of the AUX relays has fused.

yeah, that's why I stretching my head a little on this one.  I've replace all the relays, but maybe there is something downstream causing a relay to go bad.  I've looked over the wire pretty well so far, checking for pinches or mouse problems and haven't come across anything.  I see one main grounding point (which I have already cleaned up) pretty much under and behind a little of the drivers seat. Assuming there is one on the engine as well.  Do you know if there are any other grounding point on the frame?  Is there a ground that gets carried up to the front by the fuse box?

I don't know about the 21s but the previous year's had several to the frame and one or two from the frame to the engine case...front CVT cover..where the main battery ground is. Key switches break internal contacts sometimes if that hasn't been looked at and nothing on the dash is water proof so..no switches or anything.

Hi Scottchai1107,

Ok yes, I agree in that you have a harness issue, potentially a ground issue. No point in guessing or diagnosing by a process of elimination of components as you will end up changing every component in the start/stop circuitry and still be in the same boat.

For the sake of your wallet stop diagnosing by process of elimination as it can get very expensive.

Start with a current wiring diagram for your ride and work through every part of the start/stop circuitry checking voltage feed, open circuit and resistance at ground points.

I will end by asking if you have pressure cleaned your ride and potentially forced water into components of the start/stop circuit. Done the same thing via a deep wade event in water?  Did this issue just occur out of the blue or did it occur after one of the above water ingress issues?

Well it's been a while, but I finally got back out to the garage and figured I give an update.  Looking back over all the wiring with a fine tooth comb, I finally found the issue.  Behind the drivers front tire, I found the attached photos. Not sure what got this, but all I can say is this could use some shielding here as anything kicked up by the tire could really damage a bit of wiring. After getting the wiring spliced back together everything seems to be working as expected.

Wow...yep, that'll do it...lol
