Early use of the powertrain control module dates back to the late 1970s [citation needed] - official phasing in [clarification needed] of the PCM occurred during the early 1980s when used in conjunction with electronic controlled carburetors and lockup torque converters (at the time conventional 3-speed automatics received lockup converters at ...
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.
Also the same year, it adopted shock-absorbing steering. Low-floor 4WD was also added. [citation needed] In January 2000, an Allison 5-speed automatic transmission became available. The 9- and 12-ton versions were replaced in 2010, with the other models continuing to be built for another year. [citation needed]
