Common Symptoms of a Failing PCM & Your Direct Solution
A failing engine computer can cause a cascade of frustrating issues that can be difficult to diagnose. If you’re experiencing any of the following, a faulty PCM is the likely culprit:
- Persistent Check Engine Light (CEL): Especially with communication error codes (like U0100) or multiple random sensor codes.
- Poor Engine Performance: Noticeable loss of power, reduced fuel economy, hesitation, or stalling.
- Erratic Transmission Shifting: Harsh shifts, delayed engagement, or getting stuck in gear.
- Engine Misfires: The computer may fail to properly control spark or fuel injection.

Frequently Asked Questions
Do I need to do anything after I install the computer?
In most cases, this is a plug-and-play installation. However, some GM vehicles may require a simple security relearn procedure, which involves cycling the key in the ignition. Instructions are readily available online, and it does not require any special tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot program and ship your part without it. You can find your VIN on your vehicle’s dashboard (visible through the windshield) or on your registration and insurance documents.
Is this the correct part for my vehicle?
Please match your original part’s service number to one of the numbers listed in our description (12586242, YFKD, YFKF, YFKH, etc.). Verifying this number is the best way to ensure perfect compatibility with your truck or SUV.
What does “Plug and Play” really mean?
It means the computer arrives pre-programmed with your vehicle’s specific software and calibration files based on your VIN. You can install it, perform a potential security relearn, and start your vehicle without needing a trip to a dealership for expensive programming.
How long does the programming process take?
Programming is typically completed within one business day of receiving your VIN. We strive to get your part programmed and shipped out as quickly as possible to minimize your vehicle’s downtime.
