On Cadillacs, the proper code is digitally displayed.
An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
A host of functions required for ECU software calibration, such as interface-dependent calibration methods, calibration data management, measurement data visualization and analysis, ECU programming, vehicle bus monitoring, as well as remote control through standard interfaces, are part of the product's functional complement.
Instead of a block-address translation and a hardware-driven, fixed-page address translation prescribed by the first PowerPC specification, the 5xx cores provided a software-driven translation mechanism that supported variable page sizes.
