found faulty glow plug control module after some testing replaced with new acdelco part
reprogramed through techconnect after running regen like said in procedure wouldnt program the first two time as it would say trying to connect to ecm to do programming and would time out on the third time it programed ran program in administrator mode like instructed was using a bosch vci
now the glow plug module will pass dtc self test
any insite or help would be appreciated
