Anyone know what code DNR explained -equipped dealer installed 4374 P- on a 2003 H2? I checked the RPO code to see if I had keyless entry I did not AUO or A8P. Is it possible the dealer installed a remote start? I don't know how common that was put on in 2003. Or could you tell me where to look for the vault button? that would tell me if I do or not.

Moved this to the HD forum, thinking since they share a chassis maybe some of the codes are common? Maybe some of the HD guys will have seen this particular code. DNR in general is just dealer installed "stuff" I believe.
