hello freddy - the good news is that your lexus has a self diagnosis system built into it. this is what you need to do.

drive to an auto zone or similar autoparts store and have them put your lexus on their computer to scan for trouble codes. they offer this as a free service. with a little luck this scan will isolate the problem and the fix will be quick and easy.

if this doesnt fix it for you get back and let me know what codes popped up.

here is a link to the lexus trouble codes so you will have added insight. good luck.

internal lights in the radio, call your local stereo shop & asked them if they can send your radio out for repair. It may cost less just to let them replace the radio then a repair.

start by checking fuses are there any warning lights on,some of these systems pick up the speed reading from the abs
