MACKX Posted July 13, 2021 Share Posted July 13, 2021 I’ll look in the morning if I get around a granite to get an idea on that engine brake relay location..... did you check the connector at the switch for the engine brake? Take the kick panel down on the passenger side and check the VECU module connections and make sure they arent rubbed and rotted from salt since it’s an old NYDOT truck. the lighting bolt isn’t on correct? The wiring to the cam sensor is good also ? Quote Link to comment Share on other sites More sharing options...
Dalton1 Posted July 14, 2021 Author Share Posted July 14, 2021 Haven't done that yet but will check those next, I was convinced it's an electrical problem since I can operate them with an outside 12v source no problem but I'm willing to try anything at this point. Should the o-rings just be replaced while I'm in there even if they look ok? Quote Link to comment Share on other sites More sharing options...

The wiring to the cam sensor is good also ? I have checked the connector at the switch on the dash, that all looks good. I have not looked behind the passenger kick panel yet, will check that next. No lighting bolt, I hooked my scan tool up just to check and there was no codes. Wiring to the cam sensor looked good, pulled apart the connector and that looked good, haven't pulled that sensor out yet though. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted July 14, 2021 Share Posted July 14, 2021 p.s. make sure there is no oring or debris, inside the bore in the rocker shaft, before replacing, jojo Quote Link to comment Share on other sites More sharing options...
Dalton1 Posted December 17, 2021 Author Share Posted December 17, 2021 Thought I would update the post, finally got the engine brake fixed, ended up be a file in the computer adjusted to make it work the way it was for some reason, local dealer was able to reprogram to work the way its supposed to and no issues now. I was also excited to find out they were able adjust the power while it was there from 335 to 400, definitely pulls better now. 1 Quote Link to comment Share on other sites More sharing options...
