Hi John, thanks for initiating contact. This module is generally designed to be a direct plug-and-play replacement. This means that it's typically pre-programmed and doesn't require additional programming after installation. However, there might be rare cases where specific programming or "learning" procedures are necessary. If your vehicle has received recent software updates, the TCM might need to be reprogrammed to ensure compatibility. Consult your vehicle's owner's manual - This might provide specific instructions for programming or learning procedures related to the TCM for your specific vehicle.

Hi, I'm glad to help you out. Please have your vehicle carefully checked by a certified mechanic to isolate the exact problem part. A diagnostic scan tool can also help identify the problem you are encountering. We can only give inputs but would not serve as an official diagnostic solution to the problem you have right now. I hope this helps.

Hi Frank, Aside from this item, there may be other parts that could cause the service light to turn on. We highly recommend to have the vehicle diagnosed by a certified mechanic to pinpoint what part needs replacement.
