program pcm on 2001 chevy malibu

this is how you program a brand new pcm without going to the dealer.

1. Insure that the battery is fully charged.
2. Use the scan tool in order to clear the DTCs.
3. Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall.
4. Leave the ignition switch in the ON position while observing the security indicator.
5. When the security indicator turns off, which can take up to 10 minutes, turn the ignition switch off. Wait 10 seconds.

The BCM (body control module) and the PCM (power control module) will learn the new code on the next start attempt.
Note: you need to set the monitors before you can actually get the smog done. To do this, drive your vehicle about 50miles highway and maintain 65mph for atleast 10min. Then use any obd2 scanner to check the monitors
