Frequently Asked Questions
Do I absolutely need to provide my VIN?
Yes. Providing your Vehicle Identification Number (VIN) is mandatory. We use it to load the exact, correct software from GM for your vehicle’s specific configuration, including engine, transmission, and emissions options. This ensures the 1999 Alero PCM 9357034 works perfectly right out of the box.
Is this part difficult to install?
For most individuals with basic mechanical skills, this is a straightforward installation. It typically involves disconnecting the vehicle’s battery, locating and unplugging the old module, unbolting it, and then reversing the process with the new one. Always consult a repair manual for your specific vehicle’s procedure.
Will this fix my car’s specific problem?
This PCM will correct any issues directly caused by a faulty engine computer. While it solves a wide range of problems, including many common DTCs and performance issues, it’s essential to have your vehicle properly diagnosed to ensure the PCM is the root cause of the problem and not a faulty sensor or wire.
My original part number is different. Will this still work?
Yes, this module is a direct replacement for all service numbers listed in the compatibility chart, including 09356741, 16236757, 9357440, and others. As long as your vehicle is listed, our VIN programming ensures this unit will function correctly.
Is any additional programming or a ‘relearn’ procedure needed?
In most cases, no further action is required. Because the unit is pre-flashed to your VIN, it is a plug-and-play solution. However, some GM vehicles may require a simple security relearn procedure (often called a VATS or Passlock relearn) which can be done without special tools and typically takes 10-30 minutes. Instructions are readily available online.
