Signs that my alternator is going out on my lexus gs 400

SOURCE: 1998 Lexus gs 400 vsc light stay on -solve this-

does it go off if u un-plug the switch? if u un-plug it and it goes out I think that you have a bad switch. hit a gunk yard and pull one out for 10$..Matty

SOURCE: 1993 Lexus GS 300 won't start. Alternator fine,

fuel pump could be out

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

Your throttle position sensor might be stuck on the wide open throttle setting!

Do you have any check engine codes? Is the check engine light on?

It might not be if the TPS is still in the normal range...but is just sticking open.
