Hello and welcome!

My name isCustomerand I can assist you with your question.

Expert:  Amedee replied 6 months ago.

YES, this can be done. You would need to tap the disarm wire or circuit to ground. If the door is open when doing this, the jamb switch will have to be held in. Verify that all ajar switches are open to ground. All should have 5 volts or above for the module to disarm. Also, the keys need to be out of the ignition switch.

Expert:  Amedee replied 6 months ago.

Here is a wiring diagram of the BCM and security features of this vehicle. You can see the disarm circuit on pin 10 of connector 3 of the BCM.

THIS IS LESS THAN EXPECTED ...TAP TO GROUND? DO I SPLICE IT AND RUN IT TO GROUND?...THE ALARM IS STILL GOING ON I HAVE TO PULL THE BATT TO WORK ON IT
Expert:  Amedee replied 6 months ago.

Hello and sorry for the delay! Was having some connection problems.

Expert:  Amedee replied 6 months ago.

Do not splice. Cut it and tap it to ground or attach it to ground. Try tapping it to ground first to see if that does the trick. If not, you may have to permanently attach it to ground.

Expert:  Amedee replied 6 months ago.

I would go right to the BCM and ground this wire. This will be sure the BCM gets a signal in case there is a wiring issue on that circuit.

SORRY...WHERE IS THE BCM LOCATED? I WAS TOLD TO DO THIS BY THE DRIVER SIDE KICK PLATE
Expert:  Amedee replied 6 months ago.

Let me find you a pic

Expert:  Amedee replied 6 months ago.

The BCM is located on the Lower LH Side Of I/P

Here is the R and R procedure. (just so you get an idea of where it is..)

Remove the steering column opening cover/knee blocker from the instrument panel.
Remove the four screws located below the outboard switch pod that secure the Body Control Module to the instrument panel armature Body Control Module Remove/Install.
Move the BCM towards the steering column far enough to access the three wire harness connectors.
Unplug the wire harness connectors from the BCM.
Remove the BCM from the instrument panel.
Reverse the removal procedures to install. Tighten the mounting screws to 2.2 N·m (20 in. lbs.)
