Engine Control System Failure Warning

I don’t have any way of telling which code this might be, and I know there are several possibilities, but does anyone have any experience with this? It’s a 2013 Cali-30 and I already tried shutting it down for a while and restarting. I also wait for the entire self test to complete before starting every time. Thanks

Well, the battery reset cleared the message and I got the ‘Check OK’ on the next start-up. We’ll see if it lasts, I use a good CTEK tender religiously when it’s not being driven, but the battery is dated 5/18 so it’s almost like the car is programmed to throw a code at exactly three years. Thanks for the tip.

 

Good idea. I had just refueled but the cap was tight. I unscrewed it and tightened it down again anyway, just to be sure. And a new battery is on the way.

 

Well, after the battery reset the light stayed out for three days but then showed up again today. My new battery is scheduled to be delivered in the next few days and after I install it I’ll let you know if that’s a permanent solution.

 

Thanks, I plan to. There’s no dealer in the N.O. area, but there is a very reputable facility (Lindsey Automotive/Ferrari South) about thirty miles from me. When they did my annual service last Sept. they told me the battery was reading very slightly low. There were no problems back then, the battery was less than two and a half years old, the starter turned over immediately and strongly, there were no warning lights and no mysterious malfunctions with the retractable top, etc. I drive the car several times a week (about 2500 miles a year) and I was already using a CTEK tender/charger at all times the car wasn’t being driven, so I didn’t take any action back then. But I’ll be installing a new battery this weekend and then I’ll have them check for any codes.

 

Thanks for all that. I installed the new battery Saturday and the warning went away that day and the next, but showed up again Monday morning. I called and made the service appointment this morning, and sure enough the warning was gone when I started the car in the early afternoon. I drove to a restaurant with my wife, shut down for an hour and a half then drove to the hospital to visit a friend, shut down for another hour then back home. All with no warning light, but I suspect it’s going to show up again before too long. Funny you should mention the cats, because occasionally if I shut down for only a short time I’ll get a ‘converter temp’ warning on restart until everything settles down again. I also suspect carbon build up to some degree because during the warm up after first start of the day it will stumble a little until it gets to full operating temp. I’m going to pull one spark plug on each bank tomorrow to see how they look.

 

I ordered this code reader today. Do I need to reference a guide for what each code means, or is it self explanatory in the readout on the device? One other question, on an intermittent warning like I have, will the code remain in memory or disappear when the warning light goes away?

I just want to know which code it is.

 

Normal starts (no warnings and a good “Check Ok” message) for nine days straight after the new battery installation. So far, so good. I’ll have the code reader in a day or so and post again when I see what it has to say.

 

Ok, I connected my code reader and got the info shown below. Research indicates that module $7E8 references Fuel/Air Intake. You can refer to my other thread here (https://www.ferrarichat.com/forum/threads/how-do-these-plugs-look-to-you.643610/#post-147955117) about my current spark plug condition which would seem to have a direct bearing on this code. I cleared the code, and after I perform the carbon cleaning procedures recommended in that other thread I’ll run the diagnostics again as well as pull the plug again to look for any change / improvement. Btw, the plug I checked in that other thread is from cylinder #1, and since cylinders 1 - 4 are on the passenger side I‘ll assume that that is Bank 1.

Three weeks now and no further problems after installation of the new battery.
