Honda, Mazda investigated in safety test probe

Teams of inspectors from Japan's transport ministry have visited the offices of Honda Motor and Mazda Motor. They're investigating admissions by the firms that they cheated on road and safety tests. Honda and Mazda are the last of five automakers to receive visits over revelations of falsified test outcomes.

A team of five officials arrived at Honda's headquarters in Tokyo on Monday morning.

The ministry says Honda ran irregular noise tests on 22 models that are no longer in production. The weight of the cars is also said to have exceeded specified ranges. That fact was not reflected in test reports.

The ministry also says the company falsified figures for engine output tests for some of its models.

Another team of four officials arrived at Mazda's headquarters in Hiroshima Prefecture in the afternoon.
The company has admitted to manipulating test results for five models, including two that are still in production.

For those two vehicles, the firm deliberately rewrote the software it used in engine output tests. Mazda has suspended production of both models.

The automaker also says it did not perform crash tests correctly for the three models that it no longer makes.
