Tone Deafness

Here you can find even more examples:

Suzuki Hayabusa (a motorcycle) has two levels of "check engine" (actually "FI") importance. When the "FI" LED lights steady, it's a minor problem and you can ride, ECU just substituted the signal from a failed sensor with a reasonable constant. When it flashes, it's fatal and engine is stopped.

Are you sure that it's a firmware feature and not just fuel pressure issue?

AW

Yes, that would be logical. Didn't matter in the present case, as codes were pairs of digits, each enumerating a condition, not together as an actual numerical quantity. As I recall, the first digit was subsystem (ECU, ABS, etc..), second identifies what (oxygen sensor, ignition, etc..). If one system had more than 9 error codes, dunno... they might've just keep blinking it? Of course, most systems had only a few codes each, so most of the numbers that could be expressed weren't needed.

That would be a very odd fuel pressure issue, to have a problem for a moment, and then not have it again if you continue driving!

Charlie

Maybe strange, but I'd check it in the first place. Have you talked to someone with the same car to ask if he noticed similar behavior?

AW

Daltonism eh ?

I wonder if there might be a solution somehow using color filters. A simple thingie (love those technical terms) with a piece of green and a piece of red transparent plastic. You could just hold it up to your eye and tell rig ht away.

I think it would beat an auditory solution in most cases but that depends o n the environment.

The good thing is that red and green LEDs have a pretty specific wavelegth, so a filter set could be found that could tell you quickly and assuredly, and if the notch depth is steep enough (attenuation), seeing it through bot h filers would tell you for sure if it is yellow.

If you wear glasses you could stick these filters right to the lenses in an inconspicuous position, if you do not wear glasses I'm sure something can be devised.

If you do not wear glasses, don't worry, Daltonism does not prevent presbyo pia, which means if you don't wear glasses now the odds are you will need r eading glasses sooner or later. Even if not, there are probably prop glasse s you can get that are made for the movies or something, and I'm sure an op tician could hook you up with some zero correction lenses, although some of them might be a little overpriced. They do it all the time for people who get their cataracts removed and wind up with 20/20 in one eye but not the o ther.

Don't know of anyone with the same car! ;-)
