trac will not be reprogrammed. the whole unit will be replaced.Originally posted by DevilDog66:
What lexus will do is change the programming in the trac/abs ecu. With the updated ecu the trac system won't be so sensitive and will turn itself off sooner. FYI, the trac can sometimes engage for about a second or two without blinking the trac light in the dash. Thus, the owner interpets that as a hesitation. As of febuary, all IS300s made have the new ecu program, and the newer trac/abs ecu. Hope that clears things up.
