A few days ago I had a situation where my car's engine abruptly shutdown (in stop and go traffic luckily). The check engine and battery lights came on and were lit on the dash at the same time. I had to turn off the AC (it was close to 100F that day) and shift into park and push the start button again. The lights did not come on again. I hooked up a handheld scanner to the OBD2 port and no engine DTC codes were found. However I did run a battery and alternator test using the scanner, it says the battery voltage is below limit at 11.8 volts and that the alternator charging voltage is not within limits. Has anyone else experienced this? Can someone hook up an OBD2 scanner to their car and run a battery test? I have a 2015 sGT with all the tech options. Could it be that the scanner does not know how to handle the i-ELoop system and thinks there are faults?
