Convenience Module DTC 18 help.
 

Could someone provide more information on troubleshooting the error codes from the Convenience Module? Particularly code 18.

Pin 21 - Code 18 - Circuit for left front (S86/1), right front (S87/1), 23 27.0
trunk lid (S88/2) lock switch: closing time exceeded (lock switch circuit 2).

I'm not getting code 19, but code 19 is for when "openining time exeeded (lock switch circuit 1)." What is the difference? Perhaps that might clue me in where to look.

Not that i could help--but those who might be equipped would be better able if they know what car and year. Just thinkin' out loud... ;)
