Daihatsu said Friday that it has found misconduct in its crash tests for a hybrid SUV model for the Japanese market amid a growing scandal over its data tests.

Daihatsu, a unit of Toyota, stopped shipments and sales of the hybrid model of the Rocky small SUV the same day. The vehicle is also sold by the parent company as the Raize.

The development came after similar misconduct came to light in April with Daihatsu vehicles for overseas markets.

As of Thursday, cumulative sales of the Rocky and Raize hybrid models stood at 22,329 and at 56,111 units, respectively.

Daihatsu has not yet decided whether to conduct a recall, company officials said.

Daihatsu President Soichiro Okudaira told an online news conference that his company has not identified any safety problems with the affected vehicle based on available data.

The company will conduct additional safety tests on the vehicle.

"We will carry out reform at the field level while facing up to (the scandal) as a management problem," Okudaira said.

The company detected the misconduct in side impact tests on Thursday and reported it to the transport ministry on Friday.

Daihatsu had denied any irregularities involving domestic models when announcing such wrongdoing on four overseas models in April.

On Monday, Daihatsu set up a third-party committee to investigate the scandal.
