Check engine light??
I have a 1990 LS400. The check engine light and trac off light are both on. The owners manual says only on california models can I run a jumper wire to see whats wrong. Is this true, or does this work on all models??

pull your codes
Go to an Auto Zone, Pep Boys, Advance Auto, or whatever your local auto parts chain is. They will have something to pull the diagnostic codes for you. My guess is your oxygen sensors, common cause of this symptom. Post back and let us know what you find out.
Good Luck!

Not true.
Go to SC400 site and search on the subject. I posted the procedure on how to retrieved the code last year. You have to know the code before trouble shoot the problem. Post back the result and someone will help you on the code
