Nissan Motor Co. has downgraded its group operating profit outlook for the year through March due to an inspection scandal, while raising its net profit projection to a record high following the U.S. tax overhaul.

The Japanese automaker slashed its group operating profit outlook for fiscal 2017 to ¥565 billion ($5.1 billion) from its previous forecast of ¥645 billion.

In November, Nissan had downgraded its group operating profit estimate due to costs related to a data inspection scandal in which uncertified workers were carrying out final car checks in violation of regulations. The company was forced to recall 1.2 million vehicles in the domestic market.
