TOKYO, July 31 (Reuters) - The Japanese government

ordered Toyota Motor ( TM ) on Wednesday to make "drastic

reforms" after discovering new violations in the automaker's

vehicle certification procedures.

In a so-called corrective order, the transport ministry said

on-site inspections had uncovered widespread, intentional

misconduct and irregularities in seven additional models that

had not been previously disclosed.

Toyota ( TM ) said the corrective order instructed it to "make

drastic reforms to ensure appropriate certification operations".

The automaker added it was in the process of confirming

compliance with requirements for the models involved, and that

customers did not need to stop using affected vehicles.

Earlier this month, Toyota ( TM ) said it had not found any new

cases of wrongdoing in car model certification applications

beyond the ones it had already reported in June.

Toyota ( TM ) and four other vehicle makers admitted in June they

had submitted either flawed or manipulated data when applying

for certification of vehicles.

Toyota's ( TM ) wrongdoing involved three production models - the

Corolla Fielder, Corolla Axio and Yaris Cross - and discontinued

versions of four other models, including one sold under the

luxury Lexus brand.

Toyota ( TM ) said it was planning to resume production for these

models from the beginning of September after the transport

ministry confirmed they met compliance requirements.

The Japanese automakers conducted the investigation after

the transport ministry ordered industry-wide checks of

certification practices following a safety test scandal at

Toyota's ( TM ) Daihatsu compact car unit.

The ministry said six of the seven additional Toyota ( TM ) models

with irregularities were also certified in other countries, and

it had alerted overseas authorities about the issues.

Four of the additional models - a minivan sold under the

names of Noah and Voxy, and the RAV4, Harrier, and Lexus LM -

are still in production by Toyota ( TM ) while three are no longer

manufactured.
