Expert Insight from the Shop Floor
“We had a 1997 Buick LeSabre come in that had its owner completely stumped. He’d replaced the fuel pump and multiple sensors trying to fix a random stalling issue. A quick scan showed no communication with the engine controller. The original PCM was failing intermittently. After installing our pre-programmed 1997 GM 16218070 PCM and performing the simple 10-minute security relearn, the car started right up and ran smoother than it had in years. Don’t waste time and money on guesswork; the engine’s brain is often the root cause.”
Frequently Asked Questions
Do I need to do any programming myself?
No. This unit arrives pre-programmed to the VIN you provide after your purchase. It is designed to be a plug-and-play installation. The only additional step you may need is a simple security relearn procedure, which does not require any special tools.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your VIN. You can also send it to us through the contact form on our website with your order number. We cannot ship the part until we have programmed it with your VIN.
What is the security relearn procedure?
For most 1997 GM vehicles, it’s a simple process. After installing the new PCM, turn the key to the ‘ON’ position (without starting the engine) for 10-12 minutes, or until the ‘Security’ light on the dash stops flashing and turns off. Turn the key off for 10 seconds. Repeat this cycle two more times for a total of three cycles. The vehicle should then start and run normally.
Will this fix my specific problem or check engine light?
If your vehicle’s issues have been correctly diagnosed as a faulty PCM, then this part is the solution. It will resolve check engine lights and performance problems directly caused by the computer, such as internal module errors (e.g., P0601).
