Received my new truck last night and I am absolutely thrilled 8). HO Cummmins feels every bit as powerful as my V10 when accelerating, although the drivetrain still feels fairly stiff. Can't wait to experience this puppy after break-in.<br><br>A question, the overhead EVIC buttons don't seem to match the service manual. Wanted to turn off horn chirp as the service manual says you can on the EVIC, but could not figure out how to get the unit into programmming mode. Anyone been able to do this? How do you do it?

 

I read in the owner's manual how to do it, but have not tried the procedure yet. I'll try it later and let you know if it worked.

 

I thought the horn chirp was done by programing the horn...in my manual it was something to do with turning on the lights and the ignition key...worked fine...

 

Check the owners manual for the procedure. You do it with the key fob and the ignition key The EVIC console in the service manual is not what we have.

 

Yup, what TinJim said, did it myself<br><br>Hunter

 

The horn chirp feature can be disabled by using the following procedure:<br><br>1. Enter your vehicle and close all doors.<br><br>2. Fasten your seat belt (fastening the seat belt will cancel any chiming that may confuse you during this programming procedure).<br><br>3. Place the key into the ignition.<br><br>4. Turn the ignition to the ON position (do not start the engine).<br><br>5. Press and hold the LOCK button on a programmed (i.e. functional) key fob.<br><br>6. Continue to hold the LOCK button, wait at least 4 seconds, but no longer than 10 seconds, then press and hold the UNLOCK button.<br><br>7. When a single chime is heard, release both buttons.<br><br>8. Turn the ignition to the OFF position or wait 60 seconds.<br><br>9. Test the horn chirp feature by pressing the LOCK button on the key fob with the ignition in the OFF position, or the key removed.<br><br>10. To reactivate this feature, repeat the above steps.

 

I followed the insturctions in the manual and it worked for me.<br><br>jt

 

Same here; page 19 of the owners manual.

 

I did it! No more chirp. Thanks for the info.
