Hook n ladder 1 Posted December 3, 2015 Share Posted December 3, 2015 I have a 98 Ch613 E7-427. I dont know what generation ECM is in it and it fires off the same code a few times a day. Can someone tell me what generation it is and what code # 4-6 would be? Is there a list of codes somewhere ( dont say the dealership). They flash me the same code $$$$$$$.Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/42926-trouble-code-question/ Share on other sites More sharing options...
Challenger Posted December 5, 2015 Share Posted December 5, 2015 Etech engines and VMAC III came out in 98. If it has EUPs, its an Etech and VMAC III. There would be 6 EUPs on the right side of the engine, each one has an injector line, they are covered with a heat shield and are just below the exhaust manifold. If it has an injection pump its VMAC II. 4-6 code for VMAC IIITachometer output-----voltage high or voltage lowI dont think Ive ever seen this code before. Maybe someone else could give more info.
