by it you mean display? So for that I need to remove all unit out, is that right?
May I disconnect it when my car is working?
Thanks

you'll have to get the top of your dash pad (at least lifted) up to get the instrument cluster out enough to pull the cables off. I would not do this without first disconnecting your battery for at least 20 minutes- otherwise you could set some (other) codes.

You asked how to disconnect it...Lee told you there were 2 wires. If you want it disconnected all the way, you'll have to pull both cables off. However, like he said, it's most likely an issue of one of them loose or corroded. Check them and clean them if necessary and make sure they're secure. Like Lee, I'll bet this will fix your issue.

If it were me I would replace that INFO switch before permanently disconnecting. If that doesn't do it, then thoroughly clean all contacts on your cable connections. That's good information that I like to have.

I tried but without result. As I understand I can only switch off the display with a clock, It's all I can do.
Thanks everybody
