Theft deterrent module preventing new re-manufactured engine from starting

Hi,

Is the anti-theft light staying on all the time? Was this a problem prior to the repairs?

As far as the anti-theft module, it is located on the steering wheel. There are two ways to reset it. One is with a scan tool and the other without.

I am going to provide the directions for relearn procedure without a scan tool. It will take 30 minutes to complete. Follow the directions below.

________________________________________________________

30-MINUTE RELEARN PROCEDURE
Use this procedure after replacing the following components:
- The passkey III (PK3) keys
- The theft deterrent control module
- The PCM, see important above

IMPORTANT: This procedure is not available on vehicles equipped with option code (Z49 or BAE).
If replacing a theft deterrent control module with an GM SPO Replacement Part, perform the procedure to setup a new theft deterrent control module prior to the 30-minute relearn procedure.

1. With a master passkey III key (Black), turn ON the ignition, with the engine OFF.
2. Observe the Security telltale, after approximately 10 minutes the telltale will turn off.
3. Turn OFF the ignition, and wait 5 seconds.
4. Repeat steps 1 3 two more times for a total of 3 cycles or 30 minutes.

IMPORTANT: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

5. With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
6. With a scan tool, clear any DTCs.

If the module needs replaced, here are the directions for that process. The attached pictures correlate with the directions. Note that the new module will need programmed.
