This SAE Recommended Practice provides a development or possibly interim production communication protocol between engine@ transmission@ ABS/traction control@ and retarder systems until higher speed communication links are established. Rationale??SAE J1922 is no longer actively supported by a current ECU and has been superseded by SAE J1939 on all current North American trucks@ but it is installed and working in thousands of trucks today. SAE J1922 is being moved to a Noncurrent status@ since it is not being implemented in new products@ but still needs to be available to maintain the trucks that are using it.
