The low battery voltage may have triggered several trouble codes in various systems. First, I would make sure the battery is good and the charging voltage is in spec. Next, steer the wheels straight ahead and disconnect the battery; let it sit for a couple of minutes. Reconnect the battery cable, start and drive. If the lights are still illuminated, then you'll have to get the codes retrieved and erased (and, if needed, diagnosed) with a capable scantool. An OBD II code reader will not access ABS/Traction control, 4WD and other non-powertrain system codes.
