{"product_id":"engine-control-module-48","title":"Engine Control Module","description":"The Chrysler 56044564AJ is a remanufactured Engine Control Unit (ECU), Engine Control Module (ECM), or Powertrain Control Module (PCM) specifically designed as an exact fit for the 2004 Jeep Grand Cherokee equipped with the 4.7L V8 Power Tech engine. This unit is a direct replacement for multiple part numbers, including 56044564AA through 56044564AJ, as well as P56044564AJ and R6044564AJ.\n\nThis remanufactured computer has undergone rigorous testing on a state-of-the-art vehicle simulator, verifying over 25 internal circuits. This includes checks for reference voltage, ECU power-up and communication, fuel pump\/main relay function, and injector\/coil testing. Typical failure points in JTEC style ECUs have been addressed during the rebuilding process. Compatibility is confirmed for both 4x2 and 4x4 models.\n\nInstallation requires disconnecting the negative battery terminal before removing the old module and installing the new one. For a plug-and-play experience, the unit must be programmed to your vehicle's VIN and mileage. Several vendors offer free VIN programming services if you provide the necessary information during checkout. Most JTEC style ECUs do not have SKIM security and are plug-and-play after programming, though buyers should verify their vehicle's ignition key type. A potential caveat is that one mounting point may be missing on this unit, though the remaining two are sufficient for secure installation.\n\nThe unit comes with a 90-day warranty from the date of purchase. Optional core returns may be available for a partial refund.","brand":"Jeep","offers":[{"title":"Default Title","offer_id":52687384445240,"sku":"56044564AJ","price":118.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660192412.png?v=1784883520","url":"https:\/\/store.motormia.co\/products\/engine-control-module-48","provider":"MOTORMIA","version":"1.0","type":"link"}
