Engine Control System Failure?

It happened to me and after much testing at the dealership they concluded that it was a faulty sensor on the brake pedal. It hasn't recurred since they replaced the sensor.
BTW the car drove just fine after the warning illuminated.

 

Interestingly, I just got this message today on my 612.

 

I got this on my 612 when it was new, it was a combination of a faulty fuel level sender and a mis-attached pipe in the evaporative system. Time for an SD3.

 

My gas cap was loose, which, according to a search of the F-Chat archives, can cause this message. However, tightening the cap and restarting the car didn't result in any change-- message still comes up when the check engine light should go out (about 30 seconds after engine start).

So this leaves me with two theories: 1) The loose gas cap wasn't the problem, or 2) the check engine light is latched, and won't go out unless the computer is reset.

I considered disconnecting the battery, but the manual specifies a temperature range for the ECU self learning to take place after reconnecting the battery, and it's well below that range. So I guess I will wait and call the dealer in the morning.

 

Even if you disconnect the battery the message will stay. Once a fault is logged with the fuel or emmision systems (even a loose gas cap) it needs to be cleared with an SD3.

 

Thanks. I was also warned by the dealer that disconnecting the battery (or, to be more accurate, using the battery shut off switch) would give me a whole new level of issues!

 

Got the car on the SD3 and the codes are consistent with a loose gas cap. Something to keep in mind for the future!

 

The battery is probably low, I had the same problem when I didn't drive my 599 for more than a week here in nyc. I keep it plug in to a battery tender now and have no further issues.

 

I've just had this on mine, 3 days running and spookily it first appeared 10 minutes after filling up the car, so I'm now wondering on the fuel filler cap comments? Just left it at the dealers today to get it double checked, although sods law, it cleared itself this morning before I set off. I'll let you know what they say.

 

i had it also on mine, car even went into safety mode (less power, etc); technician then put a mass-cable in the trunk to get rid of the "overelectricity" ; since then 4000 happy kilometers without any problems. at first i was also told, it could be to a maladjusted fuel-filler-cap; in my case, it wasnt the reason. regards

 

Told me today that the SD3 recorded a failure to 'boot up' due to low voltage from battery, although the battery checked out fine and I told them I always have it on the battery conditioner at home (its only 9 months old). They want me to leave it with them for a week or 2 when I'm away to try and replicate the fault in the workshop. What's a 'mass-cable'?

 

Had the same problem with my car. Switched to safety mode twice - always after some very fast AB driving... The engine/exhaust heat on longer high-speed drives (250kph+ for 5-10 minutes or so) might irritate the electronics.

 

Latest from dealer is mine will be cured after software update to rectify alleged known problem of erroneous fault code caused by false interpretation of outside temperature sensor and engine temperature sensor. We wait and see?

 

I've had the light on a couple of times, but always clears itself if I shut the car down and remove the key for a minute or two.

However, last weekend after some fast driving I went to pull out of a junction, started fine, then at 3000rpm the power seemed to die off until 6000rpm. This happened a couple of times.

Some of you mentioned the car going into 'safe mode' is this the same as you experianced, or is safe mode/reduced power mode more noticable/flagged up on the dash at all?

 

"engine control system failure" sound lke Ferrari is putting fear into buyers. If this light came on, and all it was was a loose gas cap, ANY OBD11 scan tool will work to clear the light. Any emissions related device MUST be by law, able to be read diagnosed, repaired and cleared buy an emissions inspection station, or ANY service facility with a scan tool.

 

Sounds like the same issue on my car: no special "safe mode" light or so. Just the power drops very (!) substantially. Can be a bit dangerous if this happens without prewarning...

 

Did you take your car to the dealers, or did it fix itself?
Mine has not done this now for two weeks (no matter what I try or how I drive), and I know taking it to the dealers may not be of any use as I doubt they will be able to re-create the issue.

I have asked my dealer to do some research on this before they do take my car in (as they are 150+ miles away).

 

That's true. The dealers do not seem to have a final answer to this problem. However, my car has not run into the same problem for quite some time now. Could be that the problem finally disappears without any specific reason.

 

Dealer says the software upgrade appears to have cured the fault. I'll collect the car later in the week. They also upgraded the sound system to 3.8 which will apparently cure the other occasional fault I was getting with the iPod or sometimes the radio not working.

 

Unbelievable! I took the car out for a real test drive today. Just bought it yesterday. After playing with the F1 and Auto Mode, no more than 10 minutes, the light was flashing, "Engine Control System Failure---Go to the Dealer". MIne is 06 612.

 

Check the gas cap.
