Common Symptoms of a Failing Yukon XL PCM
A failing PCM, also known as an Electronic Control Module (ECM), is the central computer of your vehicle. When it malfunctions, it can cause a wide range of frustrating and difficult-to-diagnose issues. If you’re experiencing any of the following, a faulty module could be the culprit:
- Persistent Check Engine Light: Especially with codes like P0601 (Internal Control Module Memory Check Sum Error), P0602, P0604, or P0606.
- Engine Performance Problems: Rough idling, stalling, hesitation during acceleration, or a noticeable loss of power.
- Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.
- Transmission Shifting Issues: Hard or erratic shifting, or the transmission getting stuck in one gear.
- No-Start Condition: The engine cranks but refuses to start, even with a good battery and starter.
- Failed Emissions Test: Inability to pass smog inspections due to module-related errors.
This replacement PCM is the direct solution to these problems, restoring the critical communication between your engine, transmission, and other systems.

Frequently Asked Questions
Do I need to have this programmed by a dealer after I receive it?
No. This PCM arrives fully pre-programmed to your vehicle’s specific VIN. The only step required after installation is a simple security relearn procedure, which syncs the module to your keys. We provide easy-to-follow instructions for this process.
What is the security relearn procedure?
It is a simple process that you can do yourself with just your car key. It typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’, and repeating this sequence three times. This allows the new PCM to recognize your vehicle’s anti-theft system. No special tools are needed.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add this as a note during checkout or reply to your order confirmation email with the information. We cannot ship your part until we receive your VIN.
Will this module fix my specific problem?
This module is a guaranteed fix for problems caused by a faulty PCM. It will correct internal module error codes (like P0601) and the associated symptoms. However, it’s essential to have your vehicle properly diagnosed to ensure the PCM is the source of the issue, as other sensors or wiring problems can cause similar symptoms.
Is this compatible with other part numbers?
Yes, this unit is a direct replacement for several GM part numbers, including 12200411, 12201281, 12576160, and 52369718. It is compatible with a wide range of 2001-2002 GM trucks and SUVs as listed in the fitment data.
