I was told by a toyota dealer that my ecu was bad...So I replace it and although the check engine light went out the car is still running the same(misfiring, not running on all cylinders)Help! Owner of...


If the ecm didn't fix it, I would have your ignition system checked, could be a bad ICM or a bad coil maybe. If you haven't already checked the spark plugs and spark plug wires. Did you have the ECM programmed for your car?

Where is the computer box in the Lexus LS400 located?


There are 11 electronic control units(ECU) located in the dash area. They are as follows.
Engine + trans. ecu. behind right side of the dash.
Abs + traction ecu. beside the engine ecu.
electric mirror ecu. behind upper right side of dash.
SRS ecu. behind dash at console.
Shift lock ecu. in center console near shifter.
Power seat ecu. under drivers seat.
progressive power steering ecu. behind left dash left of column.
Steering column tilt + telescopic ecu. behind left dash above column.
Anti-theft ecu. behind far left of dash.
Cruise control ecu. just below the anti-theft ecu.
My guess is you are looking for the engine ECU but you may be
looking for 1 of these in the future. Hope this helps.
