Can I use my old (non- FL40) flash with my C2100??

The light should be an icon. Check your owners manual for this icon

From my experience...
A non PATS coded key SHOULD not turn the STARTER...!

If ANTI-THEFT were invoked... you can attain a not start condition which the Owners Manual says must be cleared by the dealer.

A working PATS key should disable the anti theft... by turning the ignition on... ELSE try your other key.

The SecuriLock [PATS]
passive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.

Did you use plug and play or did you follow the install programs' directions? If you use plug and play, many features do not work.

If you did plug and play, uninstall the printer, download the current install program from Xerox (free), presuming they make one... Some printers and lots more scanners do not work with newer OS...

THEN, use the interfact that Xerox (likely) provides, to run the printer.

Newer printeres and scanners are now NETWORK based, meaning non hosted by a computer. You have to run installs on the printer AND every machine, but then anyone can scan, for example, as if they hosted the scanner.....

Do the lights come on but, just don't flash? It could be the turn signal flasher. The owners manual should show the location.

if you put a scanner on it you'll prob get a code telling you what prob is.if you have a autozone or,pepboys they could put scanner on it and tell you what prob is the only way
