Expert Tech Tip: Before replacing your PCM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections (engine block to chassis, battery to chassis). A weak battery or a corroded ground can cause erratic voltage, which often mimics the symptoms of a failing computer. A few minutes with a multimeter can save you time and confirm your diagnosis.
Frequently Asked Questions
Do I need to send you my old computer?
No, there is no core charge or need to send your original module to us. This is a direct purchase, which helps you get your vehicle back on the road faster.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We use this to load the correct, updated software for your specific truck or SUV.
Is this difficult to install myself?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module. After installation, you will need to perform a security relearn procedure, also known as a “CASE learn.” This procedure is simple and can be done without special tools. We can provide instructions for this process.
Will this fix my specific problem?
This 2002 Avalanche 1500 PCM is the correct solution for a wide range of engine performance, shifting, and no-start issues caused by a faulty computer. While it solves the most common problems, proper vehicle diagnostics are always recommended to confirm the PCM is the point of failure.
How is this different from a used part from a junkyard?
A used module from another vehicle will not have the correct programming for your VIN and specific options. Our service ensures the module is 100% ready for your vehicle with the latest software, saving you the significant cost and hassle of dealership programming.
