i have been trying to get the codes read on my envoy.
using both dash command and a plug in reader
they both say there is no connection to the ecm
i found a 1k ohm resister from the lite blue wire
and the dark blue wire on the obd socket
any one have any ideas ?
i cut the resister and disconnected the joint and have not found any changes
