kevgibbs Posted July 20, 2021 Share Posted July 20, 2021 Does anyone here know of a reliable source from where I can download and/or purchase the V-MACIII Service Software? Also, does this software work with V-MACII? Quote Link to comment https://www.bigmacktrucks.com/topic/67423-mack-v-mac-iii-294-software/ Share on other sites More sharing options...
Joey Mack Posted July 22, 2021 Share Posted July 22, 2021 It will read V-Mac II.. how 'bout this??? when the lightning bolt is 'on'..... V-Mac III, you can pull the codes. (cruise control only... Lightning bolt is on..?? Turn cruise control off..... press the cruise speed control down for 2 full seconds an count the flashes. 'pay attention'! bring a pencil and paper.. there will be 2 set's of flashes. write it down, ie: (8-2.... #2 E.U.P. ) my point is, it's easy... cycle the button until the codes repeat... Be patient.... once you have written the code's, just look it up on the web... there is a bunch of free downloads, that you can print... Been there, done That!!
