My ses light has been flashing on a 95 Chev Blazer, OBD2 system.
Had it checked by Auto Zone today. I have to keep it running or
the light resets the PCM. Checked as it was running by Auto Zone
and the code reader stated that it passed. The worker at the store
told me that his unit will not work on my blazer and only the dealer
has the unit that will work. My question isdoes that sound correct?
It is a OBD2 and not a OB1. Had it checked a few days ago at another
Auto Zone with the engine off and it stated the same thing, Passed
and showed no codes. Any help would be appreciated! Harry!
