NOT following the Aldous Voice ECU Reset

It might just take longer for all the emissions monitors to appear as completed, if you are not looking to read DTC error codes or perform a emissions test soon then you are fine.

Only the driver's side window has the "one touch" feature.

 

She will heal herself eventually. Might take a few cycles of the AC to get it to work and a few other systems may need the same. If you do not have an imminent emissions test, not a big deal. There is a simpler run cycle you can use that is not as big a pain.

Run cycle.

Turn battery disconnect switch off and turn off all accessories (stereo, A/C, etc).
Let engine get completely cold or wait at least 30 minutes.
Insert key in ignition and leave for 30 seconds.
Turn ignition to on and leave for 30 seconds.
Turn ignition off and leave for 30 seconds.
Turn ignition on, wait for Check OK, and start.
Let idle with no input whatsoever for 10 minutes.
Turn accessories back on and drive gently for 10-15 minutes at least.
You will have to insert stereo code, if required.

 

Seriously! You have to do all that every time you use the battery isolator?

 

No.

The only memory lost is the clock, radio station presets, Motronic errors and fuel trim data.

The radio and clock you are on your own. The errors are gone for good. The fuel trim data is learning full time all the time and will just relearn as you drive. If it does not run well after turning the battery back on it is an indication something is wrong and the car is needing to compensate for it. It should run well on the base settings it defaults to.
It will also need to re run all the tests and reset the monitors in the motronics and there seems to be a higher incidence of recording an error and setting a CEL when you force it to do it over and over by turning off the battery. I suggest not doing it but except for the clock and radio it will pretty much do everything else on its own just fine.

 

Of course you do not have to do that every time. It is just a shortcut for the driving run cycle Ferrari published. That one is a pain unless you have your own private track.

Like Brian said, do nothing and everything will come back to normal. But that disconnect switch was designed for doing maintenance, not for routine use.

 

FWIW, I've finished enough tests for emissions testing (I can have one incomplete in NJ IIRC) simply by driving to work with a stop for coffee! 10 miles down the freeway @ 3500rpm, 3 miles on suburban streets, shut down, and 2 more miles to work. The system seems much more flexible than the published drive cycle.

 

oh! I thought it was for saving the battery when you left the car un-used for a few weeks? Is that not a good idea then?

 

Get a battery tender....problem solved
