Is Your GM Truck or SUV Acting Unpredictable?
Is your once-dependable Suburban, Silverado, or Escalade suddenly giving you headaches? Stalling at traffic lights, shifting erratically, or refusing to start can be incredibly frustrating, especially when you rely on your vehicle every day. If you’re seeing a persistent Check Engine Light and experiencing confusing performance issues, the problem often points directly to a failing Powertrain Control Module (PCM), the electronic brain of your vehicle.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, disrupting your vehicle’s performance and reliability. You might be experiencing:
- Engine stalling or cutting out unexpectedly
- Harsh or incorrect automatic transmission shifting
- A no-start condition where the engine cranks but won’t fire
- Poor fuel economy and loss of power

Frequently Asked Questions
Do I need to do anything after I install it?
In most cases, you will need to perform a simple security relearn procedure (often called a CASE relearn or anti-theft relearn). This can typically be done without special tools and involves a sequence of key turns. Instructions are readily available online for your specific model, and it allows the new PCM to sync with your vehicle’s anti-theft system.
Where is the PCM located on my vehicle?
For the majority of compatible models like the Suburban, Tahoe, and Silverado, the PCM is located in the engine bay on the driver’s side, under or next to the battery, often mounted to the fender well or a dedicated bracket.
How do I provide my VIN?
You can add your 17-digit VIN to the notes section during checkout. If you forget, don’t worry – we will contact you via email after your purchase to request it. We cannot ship the module until we have your VIN to complete the programming.
Is this the right part for my vehicle?
This module replaces service number 12602802 and many others listed in the compatibility chart. The best way to confirm is to check the part number on your existing module. If it matches one of the numbers in our description and your vehicle is on the list, this is the correct part for you.
What happens if I don’t provide a VIN?
The programming is essential for the part to function in your vehicle. We cannot ship your order until we receive your VIN and program the module. Your order will be placed on hold until we get the necessary information from you.
Will this fix my check engine light?
If your check engine light is caused by an internal failure of the PCM (common codes include P0601-P0606), then this part is the correct fix. However, if the light is on for another reason, such as a faulty sensor, this will not resolve the issue. It’s always best to have the codes professionally diagnosed before ordering.
