streamfx -> SantaFe Remote Car Start Question (2/4/2006 4:50:25 PM)
|
Today I spent the day installing a remote car starter from DEI.. The system uses the existing security/keyless entry that is factory builtin. It works well. However we have one issue that we had to work around. To remote start the car from my hyundai supplied remote. I have to press "unlock-lock-unlock".. and then lock again if I want my doors to be locked while running the car.
Heres why:
The security system in the santa Fe is set so that when you press lock on the Keychain it sends a lock to the doors, if you hit the lock button again, only the hazards flash, it already knows the doors are locked again and does not send another pulse to the motors to make sure the doors are locked.
This is why I had to use the U-L-U (unlock-lock-unlock) sequence. We used two diodes from the unlock-lock motars to the input on the DEI. I was hoping to use a L-L-L sequence to start the car. But the motors only get one lock pulse.
Do you know if there is a way to reprogram the car's system to always send a lock pulse to the doors when you hit the lock on the keychain? I couldnt find out the details on the hmaservice site. Just wish we could use a simple L-L or a L-L-L sequence. Thought about wiring the DEI input to the hazard flashes, but wouldnt that be funny if someone set off the car alarm and the car started! Or if I put on the hazards, the car would start.
But on a side note it is working. I have a 2002 2.7L santa fe and a 2004 3.5L santa fe and they both work great! Only took me about 2 hours per car.
Any suggestions on how to get the factory security to always send lock pulses to the doors would be great!
Thanks
