Update,finally was able to pick up my car on saturday;after spending about a month at the dealer good thing they gave me a loaner vehicle a 2016 chevy tahoe ltz very nice suv;recapping the engine through a fault code for the throttle body;throttle body was then replaced following the service procedure including the relearn process thats when the fun began,as the tech was performing the relearn procedure the car keeped throwing the fault code #p2176,the ignition circuit voltage would jump and stay at 24 volts;that circuit should only be at 12 volts.the car still had the original battery,the battery was load test several time and checked out good,even though it checked out good we replaced with new oe battery,retryed the relearning prodecure again still same issue of the fault code #p2176 setting about 30 seconds into the relearn procedure;the alternator was making a whinning type noise for a couple of day prior to the car going into the shop;we then replaced the alternator with a new oe alternator assembly the whinning noise was gone,now with a new battery and alternnator and throttle body assembly,tryed to perform the relearn procedure again,still after 30 seconds into the relearn procedure the fault code #p2176 sets and the ignition circuit voltage jumps to 24 volts,the tech then gets in contact with gm technical ass't to get some help after spend hours on a confrence call with about 4 engineers they then determin to replace the ecm,we then had to order a new ecm which took a couple of days,the new ecm arrived and then the tech installed the new ecm then proceded to program everything;thinking this would be it,as its being programed the same fault code came back #p2176.wtf this dealer is the exclusive repair shop for all the police"ppv"caprice in the area which include the new jersey state police and port authority and all the local police in the area;unfortunately it was bad timing that i am having this problem because the tech that has been woring on it was going on vacation;i have been a customer of this dealership for over 25 year and i know this tech very well he is one of the best tech at this dealership when people come in for service they always request him to service there car's. Maybe it was best that he was going on vaction because when he came back he would have a clear head,because that code#p2176 is kind of straight foward once the throttle body is replaced just relearn idle,now the tech came back from vacaction and had to remove the fuse box from under the hood and had to expose the main wire harness loom,now it then became a tedious task to now remove wire by wire to see what cirucit the voltage would finally drop to 12 volts,keep in mind that wire harness contains over 100 wires he had to go one by one;after going through them and tightening all the pin connector in the fuse box and the connector end into the ecm the voltage was steady at 12 volts;then proceded to relearn system in less than a minute the system was able to be relearned and no fault code,somewhere in the harnees between the fuse box under the hood and the main harness that goes to the ecm and into the car along the right side fender assembly that was the problem causing the voltage spike;they then called me to come and road test the car,which i did for about 125 miles the car runs like it did when it was new.i am just glad that i did not have to replace the under hood fuse box and complete wire harness;now had the car back for a couple of days and its running great;this was an unusual problem that the dealer and gm technical ass't haven't seen
