How to read ECU error codes on 2001 Lexus LX450? I´m trying to figure out strange warning buzzer. It comes on about 5 seconds after turning ignition key on. It stays on no matter what. I’ve tried disconnecting the battery for about 2 hrs, buzzer came back. Thanks in advance.
Answer: It does not sound like a code problem, if it was you would have a check engine light,
I would suggest pulling fuses one at a time until the buzzer stops and
then see what is on that circuit, it maybe a relay that has a poor
ground that will make them buzz.
