I need some help/advice. :o:
Until today the 03 dmax has operated great. Today when using the factory remote to unlock the doors and dis-arm the alarm system, I noticed that the previously programmed horn/lights to flash when arming and dis-arming no longer work. Now when I arm the system...with the doors closed of course. I hear the interior chime sound three times in a row, the doors all lock, but no lights flashing or horn beeping. Any info that I could get would be great. I tried checking the fuses...seem to be fine. I did recently replace the front amber turn bulbs, don't think that would cause a problem. I also recently replaced the stock tail lights with Led units. The new bulbs up front and the led tail lights have been installed for two weeks and the alarm just today acted up ????????

As an added note...I have not yet disconnected the battery - was not sure if I need or should do this to reset computer. I also recently did the "all on high beam/low beam mod" however the alarm system worked fine even after performing the mod.

Have you checked that setting in the DIC to make sure it's still set that way?

srofe,

Yes the DIC is set the way it should to correct the problem. I feeeel sooooo stewpid ! Seems that it way all along the passenger door was not completely shut. I thought it was strange that the interior chime was sounding ....kinda like when you leave your headlamps on....:banghead:
