{"product_id":"4-3l-engine-control-module","title":"4.3L Engine Control Module","description":"The Flashmasters 12200411-FM is a refurbished and tested Engine Control Module (ECM), also known as a Powertrain Control Module (PCM) or Engine Control Unit (ECU), specifically programmed to your vehicle's VIN. This ensures an exact match for your 2002 Chevrolet Blazer equipped with the 4.3L engine.\n\nThis ECM is designed as a direct replacement and comes with no core charge, allowing you to keep your original unit. It is backed by a one-year replacement warranty for peace of mind.\n\nAfter installation, two procedures may be necessary. First, an anti-theft relearn might be required if the vehicle will not start. Second, a crankshaft variation relearn may need to be performed once the vehicle is running, which will be indicated by the \"Check Engine\" or \"Service Engine Soon\" light illuminating (trouble code P1336). Instructions for both procedures, along with the necessary scan tool capabilities to perform them, will be included with your purchase. If you do not have access to the required tools, a repair shop can perform these relearn procedures to clear the trouble code and ensure normal operation.","brand":"Flashmasters","offers":[{"title":"Default Title","offer_id":52872152973624,"sku":"12200411-FM","price":139.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4-3l-engine-control-module","provider":"MOTORMIA","version":"1.0","type":"link"}
