RAM CTD horns have no fuse!!!!

From : dave

Q: i have been having problems with my dealer installed car alarm. i have very little faith that car alarms actually help with vehicle theft but the dealer installs alarms on every car that they sell. to date i have been back to the deal 3 times with problems with the alarm. yesterday they suggested that i pull the horn fuse to stop the horn from blowing when the alarm is acting up. in looking at the fuse box and at the manual there is no horn fuse listed. today i had the alarm fixed one more time and the dealer was not able to tell me where the fuse was! it took them 2 hours to get back to me with the answer. the answer is there is no horn fuse on dodge diesel trucks!. the ecu will de-activate the horn if it is honking too much. so if the horn is honking the only way to disable it is to pull negative battery leads on both batteries pull the horn connector or pray that the ecu will disable the horn before the neighbors come out and shoot holes in your truck! i was also told that if i did the mod to make the remote keyless entry open all 4 doors that the alarm will go into panic mode! .

its a relay nope not even that. in 06 horn activation is completely controlled by solid state electronics within the integrated power module. the only way to completely disable the horn is to disconnect the connectors from the horns themselves. the only fuse in the picture is the fuse that supplies power to the instrument cluster. its the cluster that either senses the horn switch or decides to trigger the horns via the alarm and communicates to the ipm via the can bus. when told to do so the ipm switches power to the two high/low horn outputs. if its an after-market alarm with its own controls then the only ways it can be triggering the horns is if it supplies power directly to the horns or if its tapped into the horn switch wiring. if it supplies power directly to the horns it may have its own inline fuse. if its just supplying a ground path to the horn switch sense circuit there wouldnt be any fuse. why would the dealer be installing an alarm when theres a perfectly good one with keyless entry and sentry key all integrated available for order from the factory by the way - all this has nothing to do with the truck being a diesel but everything to do with it being an 06 model. .
