Disable the security feature

[jeffrolet]

I replaced my turn signal/ hazard light/ wiper control/ cruise control switch module and now my 01 Silverado is in a security mode that will not allow me to start the truck. What the hell? I'm sure it is installed right as everything works, turn signals, hazards etc... Does any one know how to disable this? Please help.

This came from nelsonperformance.com This procedure should work for you. It looks time consuming, but ya gotta do what ya gotta do......

ATTENTION: Your vehicle may not start unless this procedure is performed.

GM introduced an anti-theft system in 1996 and newer vehicles. In order for your vehicle to start, you must perform the passkey relearn procedure. If your vehicle’s battery is low, it is recommended a battery charger be hooked up at this time.

This Procedure will take approximately 20-30 minutes.

After your PCM is installed, please perform the following.

You may want to be outside your vehicle so shut the door, roll down the window.



PROCEDURE:



1. Insert key, attempt to start the vehicle and leave the key in the ON position.
In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.

2. When the Security light goes OFF, turn the ignition to the OFF position.
Leave ignition OFF for 20 Seconds.

3. Attempt to start the vehicle again and leave the key in the ON position.
In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.

4. Turn the ignition to the OFF position for 20 Seconds.

5. Attempt to start the vehicle again and leave the key in the ON position.
In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.

6. Once this entire procedure has been completed (three times) your vehicle will start on the fourth attempt.


Note: Some vehicles perform the relearn in a different sequence. You may notice your security light, battery light and abs light will alternate. Once the security light is left out of the sequence that is considered one step. Repeat the procedure two more times and on the fourth time your vehicle will start.





FAQs:

- The procedure was just completed now my car is making a clicking noise when I attempt to start it.

Your battery may have become too weak to crank the engine over.

- I performed the procedure and my vehicle still doesn’t start

Please repeat the procedure again.

I appreciate the research but your suggestion did not work. The security light alternated with the battery light over and over for 20 min. It never went to a solid security light. I tried waiting 20 min then in the off position for 30 sec and repeat three times but did not work. Does any one else have any ideas. I can't believe this is such a mystery.
Thanks again
