There is a procedure for reading the codes without the diagnositic
machine. It's in the service manual (a must if you plan to do your own
maintenance). My first recommendation is to clean the ECU contacts with
DeOxit or Stabilant (See the 164 tech notes, section 40 for product info).
That did the trick on my LS. Of course you have to reset
the light afterwards. You can remove the ECU fuse in the front of the engine
compartment to reset the check engine light.
