How do i get the service mode on JVC XL-MC222.

Contact JVC directly to request the manual.

Ebay has several for sale.

Try contacting vendors such as one with original box to see if they have an operating manual.

I didn't find an operator manual for this 1995 electronics device.

Registration required at the site below for a service manual.

Appears to be for a 1995 CD player.

Not the Onstar. You have an amp in it that needs rewired. Color code for wires are so different. I use an ohm meter to fix the problem. Just a note. Onstar does't work after this.

If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

What size engine ? 4.3 L vortex P0300 random misfire code is usually associated with vacuum leaks , but could also be low fuel pressure , plugged fuel filter , fuel pump problem , clogged injectors etc... doing fuel pressure an flow testing would confirm or eliminate that as a problem . Fuel injector balance testing would confirm or eliminate clogged injectors .

sounds like the laser is dirty or has gone bad also could be the the little electric motor has gone bad better off getting a new one

Hope you can find it on
