Hello and thank you for trusting us with your Toyota question, My name is XXXXX XXXXX X will be assisting you today.
I just would like to verify, is your check engine light on now along with the other lights?
OK Did the dealership provide the trouble codes from the last times? like on the reciept what was their description of the problem for my reference?
the reason that i asked for this is that i am trying to understand exactly what's going on with the vehicle so I can give you accurate information. thank you.
OK, I don't know what to tell you about this problem since I don't have the codes, I am aware of the abs ecu problem but I am not sure about the brake booster.
The abs ecu problem is a known problem with your model sequoia. But the brake booster I don't know about. Now if you want to check their work real quick, stop by any auto parts store and have them read the codes for you, they will do so for free, get back to me with the codes and I'll give you an idea of what's going and why the lights are on now.
