tim K Posted August 24, 2016 Share Posted August 24, 2016 so i have two problems coinciding with one another.first off,1994 CH613 extremely randomly dies going down the road. elec mal light comes on. sometimes you can cycle the key and it will fire right back up without skipping a beat. sometimes it needs to sit for 10-15 minutes then it will fire up. radiator switch has been jumped out. second issue is cruise control is not working. i cant pull the dummy codes off the dash to try and get a start on the first issue. the switches both have power on dash. im on the way out to check clutch/brake switches. not sure that would interupt me from getting codes out of the dash though?

tjc transport Posted August 24, 2016 Share Posted August 24, 2016 cruise control off, flip the set switch and read the malfunction lite flashes. that will be your diagnostic trouble code. once you have the code you will know where to look.

tim K Posted August 25, 2016 Author Share Posted August 25, 2016 had a bad brake and clutch switch. it waited till it died to give any codes 6-2 & 6-3 i have a turbo speed sensor on the way for the 6-2. 6-3 is a ground bad or comm to the ecm. looks like im going hunting wires Quote Link to comment https://www.bigmacktrucks.com/topic/46562-electronic-malfunction/#findComment-343578 Share on other sites More sharing options...
turckster Posted September 20, 2016 Share Posted September 20, 2016 If this is on a 1994 CH613 then that turbo does not have a speed sensor. Turbo speed sensor was not introduced until v-mac 3 AC engines. Being a 1994 you will have the v-mac 1 electronics system, the only blink codes that start with 6 are 6-5 (Battery low voltage) and 6-6 (internal module communications).
