There is no procedure at all. Just unplug the existing Ecm, plug in this one and you are good to go... Takes 1 minute, and no tools.
Nope. You can only do "plug & play" with your own ECM, if putting in any other ECM you have to relearn the ECM.
This is for a GM vehicle (Chevy S-10), idk if it's universal for all GM:
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.
5.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(TM) Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
IMPORTANT: The vehicle learns the Passlock(TM) 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.
6.Start the engine, the vehicle has now learned the Passlock(TM) Sensor Data Code and/or password. 7.With a scan tool, clear any DTCs if needed, history DTCs will self clear after 100 ignition cycles.
