HER2005 Posted August 31, 2021 Share Posted August 31, 2021 Truck came in with complaint, pull SS out was damaged. Replaced output bearing, gasket & seal, along with new SS. Pickup on yoke was good. Still same 41 code & no speedo or power, checked harness on Trans. Was good checked VECU VJ2 pin 11 & 12 had 160 ohms & no continuity with any other pins against pins 11 12. Tried good VECU out of another truck no different. Put new gauge cluster & still the same. Need diagram from cluster to VECU. Thanks for any help.
