Engine Control Module / PCM / ECM
The ECU is a vital part for any vehicle, because it controls the engine. GMC engine computer has to be programmed. It stores your vehicle’s VIN, security and engine configuration software that controls many thing inside of the vehicle, especially engine. If the ECM software is not working properly or the ECM is defective the vehicle will not operate properly or won’t start at all. In this order you will receive the GMC Unlocked PCM/ECM/ECU. You cannot install used GMC ECU without programming it. The GMC dealers no longer provide them, ECU Team does!
NOTE: Please, make sure you inspect the vehicle at the certified mechanic prior to purchase the ECM. Check all the fuses, relays, wiring first. GMC MUST be scanned using GMC Tool (MDI). If something wrong happened during the programming, module locks out right away and can’t be re-programmed any longer. This is the way how Chevrolet System works.
