The Engine Control Unit (ECU) is a computer with an integrated pre-programmed and programmable chip that controls engine functions using input sensors and output components. The ECU program uses sensor data, signals from various mechatronic components to efficiently compute for performing various tasks in a car for optimum functionality. The technically advanced engineers in our company have the knowledge and high-technology tools to repair and program Used Engine Control Units for different cars. As a result, all vehicle features will be precisely maintained as they were before the replacement. The main thing that sets us apart is that we always provide premium features and services that can only be done by our professionals.
As one of the most crucial parts in nearly every modern vehicle, the ECU requires special attention and quality maintenance. Because if the ECM has any faults, it can lead to a wide range of issues with the car, sometimes even making it unsafe to drive. Speaking of which, there are many reasons for Engine Control Unit Failure:
Oxidation & Moisture: One of the primary causes of ECU failure is oxidation caused by moisture. Through the wiring, oxidation can penetrate the ECU, producing oxidization and providing a way for humidity to attack the ECU directly. Typically, this occurs after five to ten years. Oxidation can also damage the cabling between the fuel solenoid and the ECM harness.
Injector Wiring Harness: Oxidation causes a break in the injector or sensor wiring harness, resulting in an ECU failure.
Grounding Issues: Corroded wires or frames to the battery could cause poor grounding, which can result in ECM failure.
Dead Battery Cells: If a battery is kept in the rig for a long time after a cell has died, it will impair the battery's grounding and cause ECU failure.
Jumpstart: The ECM may be short if the wires were not connected properly when jump-started the car.
