Hi Everyone,
I've been trying to troubleshoot my 2019 CX9 @47k miles the whole day today. Just little history I had my Fortin Evo-One with T-harness installed myself last March and changed the car battery shortly after.
So the story began yesterday I went to do the NYS annual inspection and to my surprise the car failed the emission inspection. The results showed
Emission Readiness - Fail
Monitor Catalyst - Not Ready
Monitor EVAP - Not Ready
The guy at shop adviced me to drive the car more to reset cycle after changing battery. But the battery was changed few thousand miles ago. I also drove 3 hours that morning (about 40 miles and some idling) before going to the inspection. I googled and found a thread about Fortin remote start resets the ECU and the guy also failed the emission test because of it. evo-one resets Engine computer after remote start - Questions & Answers
This morning the first thing I did was to disconnect the Fortin Evo One and revert back to factory to try to perform drive cycle reset. I was being dumb that I disconnected the Fortin cables and reconnected to factory without disconnecting the battery first.
When I try to start the car it immediately gave me the Keyless System Malfunction and AFS System Malfunction (Auto Turning Headlight). The car won't respond to the keyfob or the door button. I also suspected if it was my bluetooth ODBII scanner that I forgot to remove overnight that it drained the battery. I could start the car fine by putting the keyfob next to the push button. I went to Autozone next to have a battery check because last time I got this error was bad battery. They checked and the battery is in good health (12.7v cold? ODBII showed 13.8v when car is running). I was able to unlock the car with my keyfob first thing in the morning before all these.
These are the things I tried and no luck.
- Car battery tested at Autozone
- Both Keyfob battery replaced
- Checked all 7.5/10/15/20/25/30 fuses
- Disconnected battery negative terminal for some time. (Twice, once 20 minutes and once an hour)
- Connecting the Fortin back (Keyless malfunction still presents with the Fortin reconnected)
- Started the car by placing keyfob next to the Push Button and drove 30 minutes twice. With some highways. I was able to get the Catalyst monitor ready but not EVAP. Somehow the TPMS light came on mid-drive but I checked the tire pressure after and they are all good at 36psi.
Below are the errors showing on my dash. I can take a photo later.
- Keyless System Malfuntion (once I step on the brake)
- Headlight icon in yellow (AFS Malfunction - it depends on steering input)
- TPMS
- The icon looks like a light bulb next to the TPMS
- The alert icon. Triangle with a ! in the middle.
I'm pretty confused right now. I googled and read every threads regarding this error and tried most stuff.
Now my 2nd to last resort is to disconnect the battery negative terminal for a longer period of time. Like 6 hours maybe? I'll reconnect and try again tonight.
I also completely removed the Fortin module and reverted to factory connection. Also made sure all connection is tight.
I feel like if I can't get this resolved by tomorrow I will have to take it to dealer and also get the emission issue fixed.
Thanks for reading. Let me know if you have any advice.
