The automotive giant said in a statement that an investigation found that irregularities occurred during the horsepower output testing for the certification of three diesel engine models. The Toyota Industries Corporation (Tico) also decided to temporarily suspend shipments of the affected engines.

Toyota explained that during certification testing by a special investigation committee, the horsepower output performance of engines was measured using ECUs with software that differed from that used for mass production so that results could be measured to make values appear smoother with less variation. Ten vehicle models are using the affected engines globally, including six in Japan.

Toyota noted that it has re-verified the mass-produced products manufactured at the plant and confirmed that the affected engines and vehicles meet engine performance output standards. It stressed that there is no need to stop using the affected engines or vehicles.

"Going forward, we will provide detailed explanations to the authorities and promptly proceed with appropriate measures, including conducting testing in the presence of witnesses if appropriate.

"Certification consists of having the national authorities inspect and confirm in advance that vehicles meet various standards so that customers can drive their vehicles with peace of mind. We consider the appropriate process of certification to be a major prerequisite for doing business as an automobile manufacturer.

"We recognise the gravity of the fact that the repeated certification irregularities at Tico, following those at Daihatsu, have shaken the very foundations of the company as an automobile manufacturer," Toyota said.

Affected engines

The 2.4-litre (2GD-FTV) used by the Hilux, and the 2.8-litre (1GD-FTV) used by the Fortuner and Land Cruiser Prado. and the 3.3-litre (F33A-FTV) engines are affected.

Toyota did not mention how the halting of shipments would affect its South African operations.
