Hey all. Just a few days ago, a couple minutes into my drive I got a “check” notification for three systems simultaneously: emissions system, power steering system, and VSA system. No obvious causes, car still seems to be running fine (though it is forcing traction control off, likely due to whatever issue the VSA system is throwing). I wasn’t doing anything out of the ordinary when these lights came on. My car is essentially bone stock: 2012 Si (coupe), with the only ‘mod’ being a Hondata FlashPro (running the Hondata stock reflash) and some aftermarket lights. I’ve already tried swapping the tune back to Honda’s stock one but the lights immediately came back. After a bit of searching, it seems I’m not the only person that has had these three lights turn on simultaneously... Many other users suggested it’s tied to aftermarket HIDs being installed without a relay/harness. I have aftermarket HIDs installed (I believe these ones, 9005: https://www.amazon.com/dp/B01H6NZ6F2/ ) without a relay/harness.
Do you think this might be the issue I’m having? Would installing a relay/harness potentially fix my problem? If so, what relay/harness do I need/should I get?
Something like this: https://www.theretrofitsource.com/hd-relay-9005.html or would something cheaper like this work: https://www.amazon.com/dp/B01CRVFKZY/ ?
I’m pretty clueless when it comes to car stuff so any help would be very much appreciated. Is there any way to test if these might be a good fix (for example, could I just disconnect my lights and see if the error lights go away? Or would that not work?)?
Any other suggestions are very much appreciated.
I’ll try to pull error codes with my flashpro tonight, but when I quickly checked I didn’t see any error codes (maybe I’m doing something wrong? Had it hooked up like I was uploading a tune and clicked “error codes” and it was blank).
Hopefully this is the right place to post this. Many thanks in advance!
