SOURCE: all dash warning lights came
You're alternator has gone bad and the vehicle was running on battery power. The "clicking" sound is your now dead battery that does not have enough power to turn over the starter. You might also want to check your power steering pump for leak. This is a know problem with early LS400s and will most likey be the cause of the alternator failure. I just dropped $1050.00 to fix the very same promblems you have.

If your is exhibiting the same signs as a dead battery it really sounds like your alternator is bad. If you are handy, you can remove the alternator and take it to an autoparts store like autozone and they will test it for you. This is not a hard job to do, usually 2 electrical connections, 3-5 mounting bolts and you have to pop the belt off. Just reverse it to install a new one. Good luck! - Nick

You may have corrosion inside your battery cables or a loose connection somewhere.
If you have a voltmeter connect one lead to the POSITIVE post of the battery and the other to the POSITIVE post on your starter while you have a friend crank the engine
WATCH YOUR HANDS!
This is called a voltage drop test and you should see less than 0.5v on the multimeter while you are trying to start it, if you have high resistance (corrosion bad connections) you will see a higher voltage. 0.5v is the MAX you should see.
Do the same test on the ground side of the circuit, connect to the NEGATIVE battery terminal and the starter case, your voltage reading should be 0.1v or less

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.
