2003 Toyota Corolla Alarm/Remote Start Wiring

Hey chris,

I have the 551-t valet remote start that I am installing on my sisters car. Which wire should I tap the Activation wire ?(WHITE/ blue on remote start) The "green" power lock wire? Will I also need a relay since it's a negative circuit? If so, how?

... everything is wired up and the remote does not initialize. Help...

Hi Chris Luongo

I am installing a ProStart Remote Starter/Door lock unit and noticed a discrepency in your previous post.  In your post of December 21, 2002

"REMOTE START NOTE:  The BLACK / YELLOW second accessory wire powers up the climate controls."

but on your web page at  http://www.carsound.com/cgi-bin/ubbcgi/ultimatebb.cgi?ubb=get_topic;f=3;t=000870 you say the black yellow is Ignition 2.

What  is the correct wire to use for the "Accessories output" ie heater fan?

Thanks for your help.

Kevin

Kevin,

The BLACK / YELLOW wire is Ignition 2.

itr 266: 

You probably don't really want to use that 551T, not only because the range of the factory remotes is lousy, but because the factory keyless doesn't work with the motor running----you'll be forced to use your key to get in.  But since you already installed it......

I think that wire on the 551T is programmable in one of the feature menus---I've never installed one of those myself.  But I think you can program it to recognize positive pulses?  If so, tie into the "lock motor" wire in the driver's kick panel---it is a thick wire that will show a positive when locking the doors----program the 551T so that you have to press "Lock" multiple times to activate the remote start; this way the remote start won't trigger every time you lock the car.

apmidura:

If I remember correctly, the horn wire is in a very small plug at the steering column, right up close to the steering wheel, next to the yellow plug for the air bag.

Thanks for the compliments!  I'd love to get a job writing technical material, but I don't really know how to go about it, at least without relocating.  The 2001 Corollas seem to be pretty straightforward, and the tech sheets I've seen are fairly accurate.  But fire away with any specific questions you have.

Kevin Rodgers:

Sorry about the mistake.  The car has two ignition wires---the BLACK/ white and the BLACK / YELLOW.  Without seeing the Toyota dealer's service manual, we truly have no way of knowing which is "ignition 1" and which is "ignition 2"-----but since they test the same, we don't care which is which.  One of these wires (I think it's the BLACK / YELLOW) also enables the climate controls.  The blue/red accessory wire powers up the radio, remote mirrors, and maybe some other things, and it's not necessary to activate this wire during remote start.

As always, though, never rely 100% on tech information like this---always use it only as a guide, and test each wire for yourself.  You can often get away with powering up an ignition wire as an accessory, or an accessory wire as an ignition........but it is wise practice to duplicate the factory functions as closely as possible.

Chris,

Are you serious?  I can't use the keyless if my remote start is activated? if that is the case, since I am not done with the install, I will exchange it for the 551-R which comes with a transmiter. If I do this, Will I just need to swap out the Brain? Where there be additional wiring I need to do or wiring I need to take out?

you've been a great help so far..

thanks in advance!

I was also told that I need to have a relay to work this because it gives out a negative pulse. This was the relay info given to me. please confirm..

87= Remote Start (WHITE/ Blue)

86= Car's Power Lock  Wire (Green)

30= Ground

85= Ground

Go ahead and check for yourself.....insert the key and start the car.....press buttons on the Toyota remote....keyless won't work.  As a general rule, most American brands allow the keyless to work at all times; most imports don't.  (A few odd exceptions though:  The Focus is a European Ford, so its keyless doesn't work with the motor on, either.)  But you should still double-check on each car you're working on.

I've never installed a 551T, so I'm not sure if that relay is required or not.  I understand that as a default, the WHITE/ blue wire wants to see a single negative pulse to start........which WOULD require the relay as you mention.......but I thought it had options where you could program it to more easily interface with factory keyless?  And I'm sure most of the wires/plugs are the same as the 551R, but I'm not sure about all of them.

If you get something like the 551R you should be all set.  The 551R only has a low-current, negative-trigger parking light output....but you're in luck because you can get negative parking lights on a Corolla.  It's in a large plug right at the headlight/turn signal switch, a green wire with a tiny white stripe......just hook up your negative parking light output directly to this.  Also, those do-it-yourself Rattler remote starts at Best Buy and Circuit City, the ones going for $80, are a rebadged 551R.

The 551R will also operate your door locks; you do lose the two-step unlocking though.  For unlocking, there are a few options:  1.  Get the unlock wire in the passenger kick; it'll unlock all doors on a single pulse.  2.  Get the unlock wire in the driver's kick, and the 551R will unlock the driver's door ONLY; you'll have to unlock the others by yourself.  3.  Get the unlock wire in the driver's kick, and set the 551R for a double-pulse unlock----it'll unlock the driver's door first, and all the others immediately afterward.

Also, do you need to have two remotes?  The 552T only costs a little more than the 551R, and it comes with two remotes as well as a few other features----if you're going to buy a second remote anyway, it's a better deal to just buy the 552T now.  (The 552T may also support two-step unlocking, but I'm not sure.)

To Chris Luongo

Thanks for all your help and writeup you posted on the 2003 Corolla.  I just finished installing a ProStart unit (remote start and door lock) with your help.  Everything worked the first time. 

I have two final questions.  Why all the talk about "Dome Light Supervision"?  I don't see were that comes into play at all when installing a remote starter.   Did I do something wrong?

Were did you install the safety switch under the hood when you did the install?  I can't see a good location.

Domelight supervision:  Firstly, I figure that months or years down the road, someone might find this thread by doing a search-----the more information, the better it will be for them.

Furthermore, a typical remote start installation would include keyless entry too, so that the user can operate everything with one remote.

On the LE models, factory domelight supervision is included, which turns on automatically when using the factory keyless entry------it can also be activated by twisting the key in the door, or by using your aftermarket remote to trip the same wire.

But with virtually all cars, any type of factory domelight supervision is rendered inoperative with the engine running-------if the customer remote starts the car, and then unlocks it whatever way he wants------the domelight's still going to go out the instant he closes the car door.  If you hook up the domelight supervision from the remote start, it still won't work exactly like the factory stuff did, but at least the light will still stay on until the driver inserts the key and steps on the brake, which was how the car was intended to operate from the factory.
