Show original supplier description
The Hyundai 39150-23950 is a refurbished and tested Engine Control Unit (ECU), also known as an ECM, PCM, or BCM, designed to be a direct replacement for the 1999 Hyundai Elantra. This unit is a plug-and-play component, meaning it requires no additional programming; simply install it, and your original keys will be able to start the vehicle. This OEM pre-owned unit comes with a 2-year warranty, with an optional 5-year warranty available. Common symptoms indicating a failing ECU include rough idle, cylinder misfires, poor acceleration, failure to be found via OBD, non-functional A/C, starting difficulties, persistent fault codes, and transmission shifting problems. Module Mechanics offers this unit as a cost-effective solution to get your vehicle back on the road. When considering replacement, it is crucial to match the original part number, 39150-23950 or 9030930059F. While this specific unit is listed as compatible with the 1999 Hyundai Elantra, it is important to verify fitment for specific trims and engine options. The unit is constructed with an aluminum body for durability and stable signal output.
