12628387 Service 12623325 - You must match this exactly!

ECU tested and does have communication and a properly functioning processor!

• You must match your part number exactly as seen above. If any numbers are off compared to your original it will not work properly.
• ECU has security and requires programming before installation. We offer FREE VIN programming so the ECU arrives and your vehicle will start once a key relearn process is completed. We will send instructions on how to complete this. During chekcout, be sure to put your VIN in the "notes to seller" field, otherwise we'll message after the purchase for your VIN.

  A crankshaft and throttle relearn are also recommended when replacing the ECU. A scan tool is required to complete the crank and throttle relearn. Your vehicle may not run properly if these are not completed. Be sure your mechanic is capable of completing these before purchasing.

• Ecu will fit 2008 and 2009 Cadillac STS ACADIA AND POSSIBLY OTHER GM 3.6L models with an exact part number match.

Pins perfect, none are broken or bent
