remote start triggering factory alarm

Hey guys, first time poster here. I have a 2001 Toyota Sequoia SUV I just installed a Bulldog 1200E remote start into. Everything went well, I used the T harness, factory programmed key in the transponder/theft bypass, and keysense wire hooked up. Eeverything works like it should when the car is unlocked, no alarm, starts fine, everything works like it should.  However, once you lock the car, after about 30 seconds of waiting for the alarm to arm itself, trying to remote start ANYTIME after that triggers the alarm.  You CANNOT remote start it with the doors locked for whatever reason without the alarm triggering.   I do not have any of the door locks hooked up to the bulldog transmitter, the lady doesnt care about the keyless entry on the bulldog unit.  I have the YELLOW /GREEN (-) wire on the truck for the keysense hooked up to the RED / BLACK (-) FASD wire on the brain of the remote start.  I also ran a jumper from the RED / YELLOW (-) wire in the drivers door to the keysense wire and RED?BLACK (-) FASD. I saw online somewhere that was the OEM alarm disarm wire. So both of those are wired to the FASD wire on the bulldog.  Sorry if you need more info or if I am being vague in anyway. I need some help here. I have put in about a dozen remote starts in the past and have had no troubles whatsoever. I hope someone here knows the Toyota alarm tricks that can help me out. This thing is driving me crazy!

Also, the YELLOW /GREEN Tach wire behind the glovebox is hooked up to the unit and I cant get the bulldog to recognize a tach signal or tach learn when its running. Any help here would be appreciated also. Is there another wire that could be used as the tach signal wire?

Thanks so much guys for any help you may offer.

While connecting both vehicle's YELLOW /GREEN and RED / YELLOW to the R/S's RED / BLACK, use a diode to isolate each.

Are you sure the YELLOW /GREEN(tach) is coming from the ECM?

Note: I'm showing you only need to pulse YELLOW /GREEN(key sense), to disarm?

Excellent reply, Chris Luongo.

Following Chris Luongo's instructions, connect the R/S RED / BLACK to the vehicle RED / YELLOW(disarm). I expect you've already designed your relay circuit, to reverse the polarity of the R/S IGNITION output for driving the bypass's GWR, and you can use that drive your vehicle's YELLOW /GREEN(key sense), as there is no GWR available from the RS-1200/E.

OK I guess I a way greener than I led on.

I have never used diodes or anything additional like that for a remote start.

I am assuming I need a relay to send a pulse to the factory disarm (RED / YELLOW) wire that was in the door? And isolate it with a diode? Am I using the terminology correctly? Hope so.  Sorry I am kind of new to the import installs yet, this is my first Toyota. 

So your telling me to take the RED / YELLOW wire that was in the door and run it to where? That is what I found online somewhere to be the OEM alarm disarm.

I am sorry to have to have it explained again, but if you guys dont mind, explain what I would exactly need to do to have this work.

The tach wire was not tested, I am sure its going to the ECM because I went right behind the glovebox to terminate it. I did not test it however, which is my mistake.

Thanks for all your help so far guys, I knew it wasnt something I hooked up wrong, I was sure there were additional parts needed, but on Bulldogs website, it doesnt say ANYTHING about it.

Sorry again guys,

Chris, I re-read your post and it makes more sense now.

Is a diode a diode or is there a specific type I should use?

So basically the RED / BLACK FASD wire gets the vehicles keysense(YELLOW /GREEN) wire AND the vehicles OEM alarm shutdown (RED / YELLOW), but each with a diode before returning to the R/S unit? Thats all?

The diode is a one way valve, allowing current to flow to but not back. Practically any diode will do in this case. Larger gauge wire? What Chris describes requires a negative output wire whenever the RS is on. Take 2 diodes and connect the banded end to this wire. take the other end of one diode and run it to the keysense wire in the truck. Take the other end of the 2nd diode and run it to trigger your immobilizer bypass. Do not connect anything to the wire in the door, or use any pulse before start wire that your Rs may have as it just isn't needed.

If you didn't install the diodes, everytime you put the key in the ignition switch it would send a negative signal to the bypass and turn it on. The diodes stop the current from getting there. Not to knock Chris's post in anyway(he's a smart man), but you really only need the diode in the keysense wire, not the bypass wire and it would work just as well.

This will defeat the factory alarm system during remote start operation:

• Connect the bypass's GWR to the vehicle's YELLOW /GREEN(key sense), using an in-line diode, with the stripe facing the bypass. Connect the R/S's WHITE(- ignition: thin wire) to the bypass's GWR, between the diode and the bypass module.
• Connect the R/S's RED / BLACK(FASD) to the vehicle's RED / YELLOW(FASD).

DO NOT connect anything to the RED / yellow. Only the keysense is needed to disarm...
