An Expert’s Note on Programming
“I’ve seen countless DIY mechanics get stuck after installing a used computer from a salvage yard. What they don’t realize is that on these late-90s GM vehicles, the PCM is tied directly to the anti-theft system (VATS/Passlock) and has specific fuel and transmission calibrations. A mismatched module simply won’t allow the car to start. Our process of pre-programming the 1998-1999 GM PCM 9357034 to your exact VIN bypasses all that frustration. It’s the closest you can get to a new factory part without the dealership price tag, ensuring the job gets done right the first time.”
Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. This PCM arrives fully programmed to your vehicle’s VIN and is ready for installation right out of the box. No special tools or dealer visits are required for programming.
What information do you need from me?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive it, as this is essential for the programming process.
Where can I find my VIN?
Your VIN can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my specific check engine light codes?
This module is a common fix for internal processor failure codes like P0601, P0602, and P0605. While it can resolve many other issues, it’s always best to have your vehicle properly diagnosed to ensure the PCM is the source of the problem. This 1998-1999 GM PCM 9357034 is the correct solution when the module itself has failed.
Is a core return required for this part?
No core return is required for this purchase. You can keep or dispose of your old module without any additional core charges.
