OK BRZ fans, found this over on NASIOC....loks like owrth a try, but as they say, "YMMV!"
The BRZ has a "maintenance mode" you can put the car into which overrides most of the
electronic
brake stuff, but no other Subaru I'm aware of has that and it seems
some other Toyotas have the same sequence. Since the BRZ does not have
this BOS behavior, I doubt it will work but you can give it a shot.
Turn on the car. The car must be FULLY warmed up. You must do the entire sequence within 30 seconds of starting the car.
- Pull the
e-brake 3 times. Hold/lock the
e-brake on the 3rd pull.
- Press the brake pedal 3 times. Hold it down the third time.
- Pull the hand brake 3 more times. Hold/lock the hand brake on the 3rd pull
- Press the brake pedal 2 more times.
- On the last press of the brake pedal, two yellow lights should have come on.
