My 1992 4 runners check engine light wont come on at start, vehicle wont pass smog. I checked fuses and sll are good. Check engine light will come on if I push the button on the steering wheel. Any ideas what my next step should be?
What button on the steering wheel?
It isn't labeled. A black button on the left side. On other cars the button is typically used for cruise control, I can push the button and it will lock, the engine light will stay on.
Do the other lights come on at start up? I sense a bad ground. When you press the button, it allows current to back feed through the light. Are there any codes?
All other lights appear to be in working order. On occasion the ect light will come on.
