Question
georg
I have the SARVC in my truck and I can monitor it with my Tech2 and the SOC has never been higher than 73%. This happens even on long trips on the highway with not much electrical load on - fuel pump, ignition, injectors, DRLs totalling maybe 20 amps, certainly not exceeding 25 amps. There is no AC on my truck and I dont keep the blower fan on. The SARVC is not even commanding the alternator to generate much current. Here is the screen from the Tech2

As you can see, the SARVC is not even trying to bring the SOC to 80 % up from the current SOC of 66%. Why is that? The GM FSM states that the SARVC strives to maintain the battery at 80% SOC.
