Engine control unit merge[edit]

What is the difference between Power-train control module and this article? Why do they both exist? --Mjrmtg (talk) 17:47, 14 June 2010 (UTC)[reply]

There is no difference between PCM and engien control unit, so I think pages should be merged. 81.201.62.154 (talk) 15:21, 25 March 2014 (UTC)[reply]
