Check charging system light comes on after about 15 sec. after starting. Battery volts at 11.3 on dash info screen before starting. Battery volt at 12.5 with voltmeter before start. Battery volts 13.7 on info screen when engine is running. Check charging system light goes off on fast acceleration then comes back on. New battery and alternator didn't fix the problem.

P0562 Excessive low voltage

When the battery system is less than 10.5 volts is when P0562 appears. and this code is usually cause by high corrsion on the positive side of the battery terminal or a loose connection at the engine fuse box battery positive connection, the worse  scenerio would be a ECM
