Stalled on highway while driving. Got it to the shoulder and had the lightning bolt. Turned off key and tries to start again and the P, R, N, D indicator is gone. No codes at all. Towedbit home. No blown fuses. Checked all of them anyway. All good. Did some troubleshooting with a tech type and found there to be a constant 10.6v on the starter cntrl wire even when the key is off. Went through the IPM and didn't find any burned items. Cleaned it all up and still nothing. Any idea's? Lost at this point.
