Get Your GM Truck Running Like It Should
Is your trusty 1997 GM truck, van, or SUV suddenly unreliable? If you’re dealing with frustrating issues like stalling at stoplights, a persistent check engine light, rough idling, or a vehicle that refuses to start, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an annoyance; it’s a critical failure that can leave you stranded. This replacement PCM is the reliable, straightforward solution to restore your vehicle’s performance and your peace of mind.
Common Symptoms of a Failing 1997 GM PCM & Your Solution
The PCM is the brain of your vehicle’s engine, controlling everything from fuel mixture and ignition timing to transmission shifting. When it fails, the symptoms can be varied and confusing. This professionally programmed module is the definitive fix for problems such as:
- Intermittent or complete no-start conditions
- Poor fuel economy and engine performance
- Harsh or erratic automatic transmission shifting
- Check Engine Light (CEL) with communication error codes (e.g., P0601, P0605)
- Engine stalling unexpectedly while driving or at idle
By replacing your old unit with this pre-programmed 1997 GM Truck PCM 16229684, you are installing a fresh, updated brain that eliminates these issues and gets your vehicle back to factory-spec operation.

Expert Insight from a 20-Year Tech: I’ve seen hundreds of these ’97 GM vehicles over the years. They’re built to last, but the electronics are their Achilles’ heel. The original PCMs are now over two decades old, and the internal components simply wear out from countless heat cycles and vibrations. It’s not a matter of ‘if’ they’ll fail, but ‘when.’ A common failure point is the internal processor, leading to a P0601 code that instantly fails an emissions test. Installing a quality, correctly programmed 1997 GM Truck PCM 16229684 is the most reliable repair to get these workhorses back in service for years to come.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the critical programming before we ship the module. We use your VIN to load the correct software and updates for your specific vehicle. You may need to perform a simple security relearn procedure (also known as a CASE learn or anti-theft relearn) after installation, which typically involves a sequence of key turns and can be done in your driveway.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
Where is the PCM located on my 1997 GM truck or van?
On most 1997 GM trucks, SUVs, and vans covered by this part (like the C/K Pickup, Suburban, Tahoe, and Express), the PCM is located in the engine compartment on the driver’s side, often near the battery or on the inner fender.
Will this fix my specific problem?
This 1997 GM Truck PCM 16229684 is a direct solution for issues caused by a faulty module.
