575M - Dashboard Dimmer switch ?

press the two small buttons left to the hazard button above at the same time...that gets you into to mode to select changes/scroll through and select. iirc the first option is the dimmer setting for the dash lights...you can increase up to setting of 30 by only pushing left button until desired level....then hit right button to move to next function.

The 550 has a rotating wheel rheostat.

 

Have a question. I noticed when I turn on my headlights the interior instrument cluster does not light up. The other Lights for the gauges and center climate control lights up but not the instrument cluster. I did play with the buttons to try to increase the lighting in the instrument cluster but nothing happens. I went all the way up to 30 but the lighting did not come on. Any guess what the problem is or am I doing something wrong. Thank you in advance. Note I just had the dashboard re-leathered and all other functions work.

 

oh, ohhh...

Do the instrument lights come on with only the sidelights on and does your sidelight (and low beam) indicator come on when you do this? i.e. this one.

The 575 is probably like the F360. There is a wire coming from the light control stalk on the steering column. It splits into wires. One wire goes to the light relays, the other wire goes to the instrument panel, not to supply power to the instrument lights, but to tell the instrument computers to light up the instruments. The instrument panel has a general power source, but this will be ok if all your other instrument functions work. Unfortunately, I don't know how closely the instruments resemble the 360's, so I can't tell you which wire to check. Traditionally, the wire will be yellow with a green stripe. Failing that, one of the circuit boards inside your instrument panel may be fried. Seems to be a common problem on the 360's.

Perhaps someone can tell you how hard the instrument binnacle is to remove or how hard it is to get to the plugs on the back?

Here is the setup on the F360. There are four connectors on the back of the instrument panel (9E, 8E, 7E and 6E).

The pin with the yellow/green wire on it in the bottom right hand corner of plug 7E should get an earth when you put your sidelights on. I have the feeling that the general architecture of the panel is the same as the 575's and should have similar plug/pin configurations.

Anyway, let us know if your dash sidelight/low beam indicator comes on with your sidelights on... or indeed with the steering column switch in any position.

 

R&R of the dash on the 575M is about an 8 hour job when someone knows what they are doing. Like the 360 (and F430), there is a thin film backlight on the entire instrument cluster, which often quits working. Looks like this, and only has one connector.

Rod at FAI knows how to pull the instrument panel quickly on a 575M. Might be worth the trouble seeing if he would teach you the trick, especially if you might hire him to repair it. He is the expert on repairing digital Ferrari instrument clusters.

Yes that Indicator does come on.

 

OK, then the signal is getting from the light switch to the instrument panel. It does sound like the panel is internally broken

See Terry's post about repairing the internal backlight circuit.
