Frequently Asked Questions
Do I need to do anything after I install this PCM?
In most cases, you will need to perform a security relearn procedure (also known as a CASE relearn or Passlock relearn). This is a simple process that can typically be done without special tools and involves a sequence of key turns. Instructions are readily available online for your specific model.
Where do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us a message with your 17-digit VIN. We cannot program and ship your module without this information, as it is essential for matching the software to your vehicle’s specific options.
How can I be sure my old PCM is the problem?
While the symptoms listed are strong indicators, it’s always best to have a qualified mechanic perform a full diagnostic. Key signs include a lack of communication with scan tools, multiple unrelated error codes, and ruling out all other potential causes like wiring or sensor failures.
Is this part difficult to install?
The physical installation is typically straightforward. On most GM vans and trucks of this era, the PCM is located in the engine bay and is held in place by a few bolts. The main challenge is carefully disconnecting and reconnecting the wiring harnesses. Always disconnect the battery before beginning the installation.
Will this fit vehicles other than the Savana 3500?
Yes. This PCM, identified by service number 12581565 and others listed, fits a wide array of 2003-2004 GM vehicles, including the Chevy Express, Silverado, Suburban, GMC Sierra, Yukon, and even the Cadillac CTS and Corvette.
