Peugeot iOn System Readiness Check Cleared

I have a 2018 Peugeot iOn, all-electric, showing an incomplete system readiness check at 269838 km. There's an error stored and a message on the speedometer. I suspect it's from a recent OBD2 diagnostics readout. Any ideas on clearing this without going to the dealership? I’ve checked the fuel cap (habit, I know it's electric) and visually inspected the exhaust system (minimal on an EV). Thinking it might be related to emissions testing readiness.

A 2018 Peugeot iOn showed an incomplete system readiness check and an error message, suspected to be from a recent OBD2 diagnostics readout. The issue was thought to be related to emissions testing readiness. A suggested solution was to disconnect the 12V battery to reset the system, but the error eventually cleared itself after a few drive cycles without any intervention.

Whoa, sounds familiar! I had a similar OBD readiness issue on my 2016 Renault Zoe after diagnostics. The check engine light was on and I was getting nowhere. Have you tried disconnecting the 12V battery for a while? It sounds like a simple computer reset, but sometimes that's all it takes to clear the codes and reset the system. Might be worth a shot before you start chasing ghosts in the exhaust system – or the lack thereof!

Interesting. How long did you disconnect the 12V battery for? Any issues with other systems after reconnecting? I'm wary of messing with the electronics and potentially causing more problems.

I left it disconnected for about 30 minutes, just to be sure. After reconnecting, I had to re-enter the radio code, but that was it. No other weirdness. Honestly, though, if you're not comfortable with it, I'd suggest taking it to a workshop. They can use a proper scan tool to clear the codes and make sure everything is running as it should. It might save you a headache. Plus, they can check if there are any underlying issues causing the problem.

Thanks for the advice! Turns out, the error cleared itself after a few drive cycles. The readiness check is now complete. No cost to repair. Appreciate the help!
