Classic fox error tra

Classic Fox reported tra incorrectly because of throttle failure and oil circuit problems.

1. Throttle failure: TRA indicator light of classic Focus model may be caused by engine throttle failure. Engine throttle is an important part to control the intake air volume of the engine. If there is something wrong with the engine throttle, the engine will not work normally, resulting in the TRA indicator light.

2. Oil circuit problem: TRA indicator light may also be caused by oil circuit problem. The oil circuit system of the classic Focus model includes oil pump, oil tank, oil pipe and other components. If any one of these components fails, it will cause problems in the oil circuit, which will lead to the TRA indicator light.
