Did you know there are some auto parts that just won't work after installing them in your vehicle? It's true. Electronics such as ECU's usually require reprogramming before they'll work in your vehicle. Many times, purchasers of used ECUs will complain that the part is defective when in fact, the part just needed a quick reprogramming.
Reprogramming the ECU takes little time and isn't all that costly. We've seen prices anywhere from around $49 to as much as $98. Dealers prices generally are on the higher end of this range.
Another thing to consider when purchasing a used ECU is its function. There are many ECUs in the average vehicle. Some control engine function while others are specifically designed for things such as navigation, seat position, climate control, keyless entry control...you name it. There's an ECU installed in your vehicle for just about every function your car performs. It's important to know WHICH ECU you're buying before you buy. If you're buying online and can't tell for sure from the item's online description, call the seller and confirm that the unit you're considering is the right part for your application.
Other parts that will require reprogramming after install include all types of audio equipment. Stereos and the likes have built-in antitheft systems which prevent the part from working if it is removed from the original vehicle. The only way to get the part to work again is to have a dealer reprogram it.
There may be other items that require more than a quick install to operate after being removed from one vehicle and placed in another. If you're not sure about a part, do some research before you buy. Smart buyers are informed buyers.
