Warning Signs Your PCM Needs Attention
If your truck is displaying any of these symptoms, a failing computer is a likely culprit. Replacing it can restore your vehicle’s performance and efficiency, erasing the constant worry of a breakdown.
- โ Persistent Check Engine Light (CEL) with codes like P0601, P0602, or P0606.
- โ Unexplained stalling or rough, inconsistent idling.
- โ A noticeable and sudden decrease in fuel economy.
- โ Harsh or erratic automatic transmission shifting.
- โ The engine cranks but refuses to start.
- โ Failure to pass state emissions testing.
An Expert’s Pre-Flight Check
Before condemning your PCM, take 15 minutes to check the basics. A weak battery or corroded ground straps (especially the one from the engine block to the chassis) can cause erratic electronic behavior that mimics a failing computer. A quick clean and tightening can sometimes save you a lot of time and money. Always ensure your foundation is solid before replacing a major component.
Effortless Installation Steps for a Confident Fix
We’ve taken care of the most complex partโthe programming. Your new 2000 Yukon XL 1500 PCM arrives ready to be installed. Follow these straightforward steps to get your truck back in top form. All you’ll need are some basic hand tools.
- Safety First: Begin by disconnecting the negative terminal of your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On your Yukon XL, the PCM is typically located on the driver’s side, under the battery tray, mounted to the frame rail or inner fender.
- Disconnect and Remove: Carefully unplug the electrical harness connectors. They have locking tabs that need to be released. Once disconnected, unbolt the old module from its mounting bracket and remove it.
- Install the New Unit: Mount your new, pre-programmed PCM securely in the same location.
- Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click into place. Reconnect your battery terminal.
- Perform Security Relearn: Your vehicle will likely require a simple security relearn procedure to recognize the new PCM. This usually involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times before starting the engine. A Crankshaft Variation (CASE) relearn with a capable scan tool may also be necessary for optimal performance.

Frequently Asked Questions
Do I need to get this computer programmed by a dealer?
No, you don’t! That’s the primary benefit of our service. We program the module with the latest GM software updates using the VIN you provide during checkout. It arrives at your door ready for installation.
What is a CASE Relearn and will I need to do one?
A CASE (Crankshaft Position System Variation) Relearn is a procedure that synchronizes the new PCM with your engine’s crankshaft position sensor. While the truck will often run without it, performing this relearn with a compatible scan tool is highly recommended to ensure accurate misfire detection and the smoothest possible engine operation.
Where is the PCM located on my 2000 Yukon XL 1500?
You will find the Powertrain Control Module on the driver’s side of the vehicle. It is typically mounted to the frame rail, located just underneath the battery and its tray.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM is responsible for controlling transmission shift points and line pressure. If the module is failing, it can cause erratic shifting. However, it’s always wise to ensure the transmission fluid is clean and at the correct level, as mechanical issues can also cause similar symptoms.
What information do you need from me?
After you complete your purchase, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to load the exact correct software and calibrations for your truck’s specific options and configuration.
