ill try that

 

Set off the alarm by locking the truck with the key fob then unlocking the door manually with the key. Get in the truck while it is in alarm, put key in cylinder and start. Should clear it out for you and next time it will not beep 3 times.

 

Let us know if it works

it seems to have mysteriously gone away without me doing anything

 

Battery going dead on ur fob?

 

Mine was doing the exact same thing for about 3 days as well... I attempted to start my truck this morning, and all lights went out (cluster and all), took the key out of the ignition and everything came back (this was repetitive)... had to tighten up the negative battery terminal connection... haven't had the problem since... not sure if these are related or not but it's what mine did

 

I've never heard of this. Maybe it had to do with some setting you accidently set. I know there's a way to set the horn up so when it locks, the horn honks and same goes with unlocking.

 

peanutbuttersports,

I am sorry you are experiencing this issue with your vehicle. This may be due to an internal fault in the BCM. This is just a suggestion, not a diagnosis. I recommend consulting with a certified technician for an official diagnosis.

MOST LIKELY... your door was Ajar when you hit the lock / unlock button.


There is a way to change the settings very easily. It's in your owners manual.

Just out of memory, it's something along the lines of put key into ignition, then hold the odometer reset button for 5 seconds, then turning key on to accessory, and release odometer reset button.

it will enter into a setting mode on your Indicator panel. then something like tapping or holding the odometer reset button toggles options.

Or maybe it's hold it for 15 seconds after putting ignition to On....


Try it out !


Edit...
I was close. Look here: Pg 198 / 199
