Honda Accord Hybrid Warning Light & System Check Issues

Hey there! I had a pretty similar situation with my 2015 Honda Insight (great hybrid too, like your Accord's cousin!). I have some experience working on cars, but this one had me stumped at first. Had the same warning lights pop up after I got my battery replaced. Turned out the car's computer just needed to complete its system checks. My mechanic explained that this is pretty common after any battery work. Cost me about 90 Euro for the diagnostic and reset, but at least it wasn't anything serious! Quick question, did you have any recent battery work done on your Accord? Also, are you getting any specific error codes? This would help me share more relevant details from my experience.

Thanks for sharing your experience! No battery work on my end, the warning light started showing up after my latest service about two weeks ago. I did get an error code scanned at a parts shop, showing P1630. My Accord's running at 30258 KM, and honestly, it's been super reliable until now. Maybe it's just being moody! Has anyone else seen this specific code? The car drives fine otherwise, but that warning light is making me a bit nervous.

Hey again! Thanks for sharing those details about your Accord. You know what's funny, I had that exact same P1630 code pop up on my Insight around the 35000 KM mark, also after a routine service! The warning light definitely made me nervous too at first, but here's what I discovered: in my case, it was actually just a loose connection in the ECU wiring harness that got jostled during the service. My mechanic found it pretty quickly, apparently some of these Honda hybrids can be a bit sensitive to these things. Cost me around 45 Euro to fix (mostly labor), and the light hasn't come back since. If your Accord's anything like my Insight, I'd bet it's something similarly minor, especially since you mentioned it's driving fine otherwise. These hybrids are pretty solid cars overall. Quick suggestion, might be worth checking if anything got disconnected during your service. Since it started right after that, it could be something as simple as what I experienced. Let me know what you find out!

Thanks so much for that detailed info! It's actually really reassuring to hear you had almost the exact same experience with your Insight. I just called my mechanic and mentioned the loose ECU wiring harness possibility, they said they'd take a look first thing tomorrow morning. You're right about these hybrids being sensitive; I've learned so much about their quirks since getting mine! Honestly, I feel much better knowing it's probably not something major, especially since it's driving perfectly fine otherwise. The 45 euro repair cost sounds way better than what I was imagining! I'll definitely update everyone once I get it checked out, but I'm betting you're spot on about it being related to the recent service. Really appreciate you sharing your experience, it's helped calm my nerves about this whole situation!
