So...I'm going to the store this morning, I get out of the car and "lock" the doors...The automatic locking wasn't working...I get back in and the usual beeps(ABS FAULT, TRACTION FAULT, SEAT BELT BEEP) aren't going...All of the sudden this time ALTERNATOR FAULT!? My headlights/taillights are flashing, interior lights are stuck on...Radio works fine. I went to the nearest parts store and had my alternator tested. It read fine and it was charging...This ever happen to anyone? Also when I turned the car off "DIAGNOSTICS MODE" flashed on the message centre. Any help would be greatly appreciated
