Called up the Casa. They say will only replace it only if one has a letter from TMPI stating eligibility for this recall.

Huh? It clearly states in the link above that Innova, Fortuner, Hilux from Nov 2004 to June 2010 are affected.

Also you can tell if your vehicle has this problem. Provided it did not deploy as a result of a collision, the airbag lamp indicator would be blinking.
