When it comes to replacing your GM powertrain control module (PCM), you need to make sure that you have the correct part number. This will ensure that the replacement PCM is compatible with your vehicle and will function properly. We’ll show you the location of the correct part number for your GM PCM. As you can see to the left, there are usually multiple numbers on these GM computers.
Why is the Part Number Important?
The part number of your PCM is unique to your vehicle and its specific engine, transmission, and emission system. This means that without the correct part number, you could end up with a replacement PCM that is not compatible with your vehicle’s systems.
Where Can I Find the Part Number?
There are a few different ways to find the part number for your GM PCM:
Owner’s Manual
The first place to check is your vehicle’s owner’s manual. This should have a section on the PCM, including the part number.
Hardware Number
GM PCMs will almost always have a segmented sticker like this with a bunch of numbers. Luckily, they label the important numbers and we’ll start with the number on the bottom section of the sticker.
This is the Hardware Part Number that designates a set of these types of computers. In this case it is “09357440”. It could technically fit your vehicle, and possibly get your car back up and running but it’s just a possibility.
The numbers on the side and very bottom are also other random identifiers that will not help. Sometimes this bottom segment of the full sticker will not be there, since the hardware number isn’t actually what’s needed.
Service Number
The number you truly want is the Service Number. This number will be near the top. This is the tag that you need. Again, you ignore the numbers underneath. You will usually find the Part Number following “Serv.No.”. In this case, the part number for this GM PCM is “09361735”. The Service number is also what you will need for other GM PCMs like this black model here.
Once you find this number, it’s time to search for your replacement PCM. If you need a replacement GM PCM, take a look through our catalog.
Consult a Professional
If all else fails, you can always consult a professional mechanic or dealership. They will have the resources and knowledge to determine the correct part number for your specific vehicle.
Online Resources
If you are unable to find the part number using the previous methods, there are also a variety of online resources that can help. Websites such as Flagship One allow you to search for the correct PCM by entering your vehicle’s make, model, and year.
Under the Hood
If you can’t find the part number in your owner’s manual, you can also check under the hood of your vehicle. Look for a white sticker or label on the PCM itself. This should have the part number listed.
Tips for Finding the Correct Part Number
Here are a few tips to keep in mind when searching for the correct part number for your GM PCM:
- Double Check: It’s always a good idea to double check the part number to ensure accuracy. This can help prevent ordering the wrong part and wasting time and money.
- Consider VIN: If you have your vehicle’s VIN (vehicle identification number), this can also be used to search for the correct PCM part number. The VIN is a unique code that identifies your specific vehicle, including all of its components.
- Look for Replacements: In some cases, your original PCM may have been replaced with a different part number. If this is the case, you will need to search for the replacement part number rather than the original.
Conclusion
Finding the correct part number for your GM powertrain control module (PCM) is crucial in ensuring that your vehicle continues to run smoothly and efficiently. By following these tips and utilizing available resources, you can easily find the correct part number and ensure a successful replacement process. If you are still unsure or have any questions, don’t hesitate to seek professional assistance. So next time your GM PCM needs replacing, remember to check for the correct part number to avoid any potential compatibility issues. Happy driving!
