Re: We need to reset the computer on a 2003 Oldsmobile...
HI there if the scan tool you are using will not reprogram the theft module the try the 10 min relearn
- Turn ON the ignition, with the engine OFF.
- Attempt to start the engine, then release the key to ON (vehicle will not start).
- Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
- Turn OFF the ignition, and wait 5 seconds.
- 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
When you changed the engine, did you use a junk yard motor?
