steering is not working at all plus my clock and my

Your elternator is bad you need to replace new one

That's correct if your serpentine belt is broken ...the elternator and power steering is not working..so check the belt first .

I am not sure if I have the belt on the engine that drives the alternator. My car is a 2006 Lexus GS300 with 220,000miles. I have never changed the serpentine belt. I guess I will change the it and see if that resolves the problem (fingers crossed). The belt is due for a change anyhow, after all those miles. If it isn't the belt then what do you recommend I should do next?

Did You change the ECU? If you did and didn’t reprogram (See the new ECU or Computer Same Thing) are VIN Vehicle Identification Number Specific to the Computer,So when you put in a Computer from a Different Car the VIN Doesn’t Match So the Anti-Theft Kicks in and That acts Like the Battery is Dead ,Won’t Start,That is one of the main reprogram things the Dealer does for $2000,Copy Your VIN from the Windshield to the New Computer with a keyboard WOW.You Can have anyone who can use a couple Wrenches and Read Change this and Reset it,go to Justanswer.com you donate whatever you feel it’s worth,tell them you want to replace and reprogram the ECU on your 06 Lexus GS and they will walk you or Whoever will Change it through it a heck of a lot cheaper then the Dealer,Never go to the Dealer unless you have a Free Recall or are under Warranty!
