- Check Engine Light: Particularly for internal module codes like P0601, P0602, or P0606.
- No-Start Condition: The engine cranks but won’t start, often due to a lack of fuel injector or ignition coil signal.
- Poor Performance: Issues like rough idling, stalling, poor fuel economy, and harsh shifting can all point back to the PCM.

It’s a straightforward process that typically takes 10-30 minutes and requires only your ignition keyโno special tools needed. Completing this step ensures your 2003-2007 Silverado 3500 PCM functions seamlessly with the rest of your truck’s systems.
