- Summary
- A service campaign will be launched December 19, 2013 to update the ECM software programming in certain 2008 - 2014 Lancer Evolution, 2009 - 2014 Lancer Ralliart, and 2009 - 2011 Lancer Sportback Ralliart built before September 25, 2013. This service campaign will be conducted in the U.S. and Puerto Rico. A Service Campaign Bulletin outlining the reprogramming procedure will be available December 19, 2013 on MEDIC and MDL. In certain affected vehicles, normal Electric Throttle Valve (ETV) fluctuations may cause actual torque to exceed Permitted Torque at low engine speeds. An improper Permitted Torque threshold may then cause false MIL illumination. A software update optimizes the Permitted Torque threshold value to minimize false MIL illumination.
