Electrical and modules
P0562 means the electrical system voltage is too low, usually a failing alternator, weak battery or bad connection.
The engine computer saw the vehicle's electrical system voltage below its normal range, usually meaning the battery isn't being charged properly.
If the charging system has failed, the vehicle can die once the battery runs down. Get the battery and alternator tested soon, and avoid long drives at night with lights on.
