Front impact In the first frontal test, the airbags fired late owing to disconnection of a satellite airbag sensor early in the impact. Toyota re-routed the wiring to the sensor and modified the software in the control unit so that the airbags fired earlier in the event of a disconnection. Euro NCAP allowed Toyota to re-test the modified car. In the repeat test, the airbags fired as intended despite damage to the wiring harness. Toyota have informed Euro NCAP that they do not intend to apply these modifications to cars already sold. The driver's knees bottomed out the knee airbag and contacted the support bracket.
