2015 Toyota Tundra Evo One remote start alarm goes off on remote shutdown

Question

**This may be a duplicate post but has more info and i will try to hide the other post

installed evo one in my 2015 tundra with OEM alarm.  The truck does remote start fine (after the doors unlock and relock) but if it runs for 15 minutes, the alarm goes off.  If I remote shutdown right after remote start, it works as it should.  If i remote start and wait 5 minutes and remote shut down the alarm goes off.  I have hooked up the keysense wire to the black wire as instructed in the diagram.  Alarm is triggered when using RF 642 remote or OEM 3x lock.  I did use a pre-wired kit that had both plug and play adapters for the Tundra.  Updated to 74.49 via flash link but no change.

Answer 1

Are you using a t-harness?

Comments

Yes, both the 2 and 7 harnesses.

Your key sense wire is not connected properly.

I did use a positap. I will double check it and solder if needed. Thanks

Redid the keysense wire, issue is resolved!!!  Thank you!

Answer 2

You should set the option 2.1 instead of 2.4 on the remote starter side.

Comments

Doing so causes the truck just to crank for 8 seconds, twice. It will not start with 2.1 enabled.

You can try leaving a key in the ignition without turning it on to see if the alarm still goes off when you remote start. If the alarm doesn't I would double check your wiring and connection.

Thanks, I may give that a shot tomorrow. One interesting note I noticed. When I do a remote shutdown, my power amp steps lower (like the door is opening, but I am not touching the truck). It’s as the Fortin is disarming the alarm, simulating a door open then the alarm goes off.   I thought about just doing a complete reset on the Fortin and start over.

Can lock or remote start the tundra with the key in the ignition.
