Guided Installation for Your 1997 Yukon PCM
You don’t need to be a master mechanic to complete this job. With basic hand tools and a little patience, you can have your truck running right in under an hour. Follow these steps for a confident fix:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Old Module: On most 1997 GM trucks and vans, the PCM is located in the engine bay, typically on the driver’s side fender wall near the battery.
- Disconnect the Wiring: Carefully unplug the large electrical connectors from the old PCM. There may be locking tabs or levers that need to be released.
- Remove the Old Unit: Unbolt the old module from its mounting bracket. Keep the hardware, as you may need it for the new installation.
- Install the New PCM: Mount your new, pre-programmed PCM onto the bracket and securely fasten it.
- Reconnect and Finalize: Plug the wiring harnesses firmly into the new module until they click into place. Reconnect your battery terminal. Your vehicle is now ready to start!
An Expert’s Note on First Startup
After installing your new PCM, it’s normal for the engine to run a little differently for the first 50-100 miles. The computer is going through a ‘re-learning’ process, adapting to your specific engine and sensors. Give it a few drive cycles to fully calibrate. Also, take a moment to inspect your battery terminals and main engine ground wires. A clean, tight connection is critical for the health of any vehicle computer.

Frequently Asked Questions
What information do you need to program the PCM?
We need your vehicle’s 17-digit Vehicle Identification Number (VIN). Please provide it during checkout or send it to us in a message after your purchase. This ensures we load the exact, correct software for your truck’s specific configuration.
Is this really a plug-and-play installation?
Yes! Because we program the module to your VIN before shipping, it is ready to be installed without any additional programming. In some cases, a simple security relearn procedure (instructions included) or a Crankshaft Variation Relearn may be needed, which can be done with a capable scan tool.
Will this fix my specific problem?
This PCM will correct issues directly caused by a faulty internal computer, such as specific diagnostic trouble codes (DTCs) or communication failures. While it solves the vast majority of engine performance problems, it’s always wise to ensure other components like sensors or wiring are not the root cause.
Do I need to send my old PCM back?
No core charge or return is required for this part. You can keep your old module or recycle it locally.
How long does the programming and shipping process take?
Once we receive your VIN, programming is typically completed within one business day. We then ship the module out promptly so you can get your vehicle repaired as quickly as possible.
