96 bonniville GM VATS resistor value

Hello room,

Need help on finishing up an alarm install on my car. Stuck on the resistor value needed to bypass the VATS. The key is measuring 1175. Do I have to measure from the actual module under the dash in the orange tubing containing the two white wires? Is it ok to use a 1000 ohm or a 1500 ohm which is included with the viper 550esp remote start? Also need to bypass the anti-teft by using the factory dis-arm wire from the alarm. Do I need to re-arm it for any reason or is it ok to keep it dis-armed? everything else is done, just need to finish this part before adding the starter kill and remote start. Any other suprise I should know about before finishing that you may know about? thanks for your help!!

This system uses a resistor in the key, use a digital volt meter set to ohms and put 1 lead on each side of the vats chip in the center of the key, find a resistor to match your reading.

Locate the Orange or Black tube running down the steering column from the ignition switch. Cut open the tube to epose the passkey wires insie. Your resistor or trumpet should be within +/- 10 ohms of the key. Either of the passkey wires can be cut. GM uses only a fixed number of different resistors with their PASSKEY/VATS system, your measurement should correspond to one of the following values.

You do not need to re-arm the factory system, just disarm the factory system when remote starting.Hope this helps and good luck.

THANKS JEFF I WILL LET YOU KNOW HOW IT COMES OUT. I HAVE ANOTHER DUMB QUESTION? BEFORE THE REMOTE START IS ACTIVATED DOES THE ALARM HAVE TO BE DIS-ARMED AND THEN THE REMOTE START CAN BE ACTIVATED OR CAN I JUST ACTIVATE THE REMOTE START AND IT SHOULD THROW THE BYPASS THROUGH THAT ONE WIRE DIS-ARMING THE FACTORY ANTI-THEFT?

THANKS

Hi Sound Pressure, you can remote start the vehicle with your aftermarket alarm armed or disarmed so long as you have the factory alarm disarming when starting by remote start. If you have any sensors (impact, glass breakage, etc) installed, just make sure you have them wired to be bypassed when the vehicle is running by remote start.

are you refering to the factory disarm or the unit that you are installing ? If you are refering to the factory alarm, the remote starter will disarm the alarm while it is remote started and when it has timed out or you have stopped the remote start sequence, it will re-arm itself.

I USED A POTENTIOMETER TO DUPLICATE THE RESISTOR VALUE. IT WAS AROUND 1172. IT SHOULD WORK THE SAME CORRECT? IF ANYTHING GOES WRONG IT SHOULD DISABLE FOR ABOUT 10-15 MINUTES RIGHT? EVERYTHING SHOULD GO SMOOTH NOW. THE MAIN THING WAS GETTING THE EXACT RESISTOR VALUE MATCH.

THANKS 12VOLT AND JEFF

Hi Sound Pressure, verify that the alarm is getting 12V+ on the ignition lead to the alarm at the alarm when the key is in the on position. Your meter will tell you for sure. If all the doors are closed, regardless of what you used to isolate them, that should not be the cause of the problem. I'm willing to bet you do not have 12V+ at the alarm on it's ignition lead especially if it will arm when the key is on.

Check the connection at the plug for the valet switch ( if there is a plug ) to ensure a solid conection. Also you may want to check the continuity of the wires to make sure that there is no breaks in the wire. Another thing to make sure is taht there are no points of entry that are open that mey not allow you to enter the program mode. Check the instructions and make sure that you are doing it correctly.

THE ALARM WILL TRIGGER ON EVEN WHEN THE CAR IS ON. You mentioned this in your statement but is the alarm activating when you remote start ? OR is it activating after you get into the car and start driving ? Test the rectifier to ensure that there is no current going through the wire. If none is present then it's OK, but if there is you will need to place a diode in line. Make sure your switched ignition wire to the alarm is actually switching off when the key is in the OFF position.

THANKYOU 12 VOLT I WILL CHECK THAT TOMORROW AND LET YOU KNOW.
