I just had a smog test done and passed with 10% of allowed or less on
all tests, but failed due to the service engine light not coming on
with the key in the run position w/ car not running. I pulled the dash
(very brittle and have to get creative to get the AC controls back in)
and the light for the check engine is fine, tested it in another hole.
Is this light required? The check gages light is on with the key in
the run position but goes out upon starting. HELP
