98 sienna remote start, alarm disarm

I am currently finishing up a remote start (dei valet 561r) install on a 98 Toyota Sienna.  After coming here for most of the information needed, I am still stuck on a few things.

One is the tach signal.  I have some documentation from the12volt that I will try out tomorrow.

The 2nd thing is the factory alarm that is currently in the van.  I would like the remote starter to utilize the factory alarm for an alarm.  I just do not know where the factory disarm and rearm are located.  It is the factory alarm from toyota.  I tried a suggestion as to whether the door lock disarms the alarm: it does not.  You need the key fob to arm and disarm the security.  Where is the disarm and rearm wire for the remote starter to connect to?

Any help would be greatly appreciated.

Thanks

Tony

Alarm Disarm     BLUE  (-)           20 PIN PLUG AT FUSE BOX OR DR.KICK PANE 
Alarm Arm                            Arms With LOCK

To test for this you might need to use key in drivers door and turn to unlock to see DisArm pulse.  Not sure on older Toyotas, but new ones like to see Keysense, too.

Thanks for the response so quickly.  As far as a 20 pin plug, I will look closer at what is around the fuse block, but I do not recall seeing a solid blue wire.  Also, is the alarm to arm when locking the driver's door?  Or should it lock using the passenger door as well?  I am not familiar with the Toyota's factory alarm.

I am not sure about the keysense, but we use a spare metal key as the main plastic key was lost years ago.

I believe Toyota didn't start using a transponder immobilizer on Sienna's until 1999, and because your van operates properly with a plain key, that confirms you don't have an immobilizer. 

Kesense is a signal that is generated when a key is inserted into the ignition switch.  The car uses this signal for various purposes.  Sometimes it's just to sound a chime to alert you that the car is off, the drivers door is open and the key is still in the ignition switch.  Sometimes it is used with the cars alarm system.

the door lock wire is also your factory alarm arm. Connect your lock wire to BLUE/WHITE (-)

Connect the unlock wire to BLUE / YELLOW (-). this will control unlock and factory alarm disarm when you unlock doors.

The independant wire to disarm without unlocking doors is BLUE (-) @ DKP, loom heading into cabin from the door.

Tach Either GRAY or BLUE @ coil pack ontop of engine. You can also use the TAN wire.

There is no bypass required for this van.

Factory alarm:

For a 1998, it's very unlikely you'll succeed in getting the remote starter to arm and disarm the factory alarm.

For Keysense use the (-) Status output.  Diode isloate it if you are using that signal any where else.

Update, I finally had some time to get outside with the van (had to replace door handles...fun). 

I used the factory key fob to arm the security system.  I then took the key and unlocked the doors from the drivers side.  It did NOT disarm the alarm system, nor did the passenger door.  I opened the door after unlocking and the alarm still went off. Bummer, was hoping to utilize it.  May be I can make it work in my next Toyota.

I also noticed that the remote start does not allow the dome light to come on after arming.  I connected the lock/unlock to the bundle of wire at the bottom of the fuse panel. (Blue/White and Blue / YELLOW)  I couldn't find the wire on the driver's door harness.  I'll have to probe again I guess.

For keysense, the -200mA won't be used anywhere else but the keysense.  Will I still need a diode for this?

No diode necessary if the R/S's (-) Staus output is only going to the vans(-)  Keysense wire. 

As for the alarm, what happens if you set the alarm (with the window down), unlock the drivers door with the key, reach into the van & insert a key into the ignition (but don't turn it), and then open a door?  Does the alarm still go off?  Sometimes keysense or keysense + ignition will turn off the alarm.

I'm not sure I understand your question.  The vans keysense signal would still work normally, it would just have the R/S's (-) Status output attached to it.

Usually the (-) Status output from the R/S is used to control the Bypass module.  Your van does not need a bypass module.  The R/S (-) Status output could be attached to the vans (-) Keysense wire to make the van think that a key has been inserted into the ignition switch during remote start.  The keysense signal is often used to turn off the alarm, sometimes in conjunction with other signals.

Don't worry too much about Keysense.  It may not be necessary for your van.  Your van might not trigger an alarm just by remote starting.  Did you find the Alarm Disarm blue wire in the drivers kick panel?

Also, on some new Toyota's, the remote keyless entry is disabled by the car when the engine is running.  That means if you remote start the van, your factory remote keyless entry will not unlock the doors.   Try starting your van with the key, then press the lock or unlock button on the factory FOB.  Anything happen?

Seems there isn't an edit post function.  I posted a reply without typing anything.

Found that the alarm disarms when you use the key to start it.  This would mean the van does have keysense and I will connect the (-)200mA output to this keysense.

Once started, the factory key fob will unlock the doors.  It will NOT lock the doors back though.

I think the goal is to just get the remote start working to the point it remote starts and unlock/lock the doors.  I would prefer to have the alarm arm and disarm from the RS fob.  Is there a way to teach the RS lock/unlock button to the factory alarm?

Yes, install the R/S unit and worry about the alarm later.  It is possible that a remote start with the Keysense signal supplied by 561R's (-) Status output will not only start the van and disarm the alarm too, allowing you to unlock the doors with the R/S FOB's and open them without an alarm.

According to the info from AudioVox site and the post from Ted, the vans alarm will turn on with a door lock.  If you attach the R/S's lock output to the van's Blue/White lock wire in the Driver Kick Panel, pressing the lock button on the R/S FOB will lock the doors and turn the alarm on.   Also, to find the lock/unlock wires in the drivers kick panel, you need to check the wire with a DMM while turning the key in the Passenger Door lock .
