TOKYO -- Toyota Motor unit Hino Motors on Monday revealed improper engine performance testing for its light-duty commerical trucks, widening a quality control scandal just weeks after acknowledging it had falsified emissions tests on larger vehicles for decades.

The company said it had not tested the emissions levels of its Hino Dutro light truck engines at least twice, as regulations require, despite submitting documents to authorities that it had done so.
