Never mind, I know where the search feature is and I did not come across it. I searched for Theft Learn Procedure. My bad as usual when i try to do something nice
That's some great info....you can actually get the relearn from one of the vendors here as well....its on there website.....PCM4Less....also if you use the search there are tons of info on this website....and a lot of reading...Couldn't find this posted anywhere, so here it is. This should hopefully save some people money instead of paying the stealership $100.00. My wife's cousin works at a dealership and gave me this.
VEHICLE THEFT LEARN PROCEDURE
30 Minute Learn Procedure
1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
4. Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes ( the vehicle is now ready to relearn the Passlock™ Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK).
Important: The vehicle learns the Passlock™ Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
Start the engine (the vehicle has now learned the Passlock™ Sensor Data Code and/or password).
With a scan tool, clear any DTCs if needed (history DTCs will self clear after 100 ignition cycles).
