The instructions for the Innova/Equus code reader that I just
bought say that the product will indeed display "pending" codes.
I'll keep this short and won't go into an explanation about the
On Board Diagnostic system. Suffice to say that a "pending"
situation is one in which the computer has registered a reading
that's out of normal range, but has not determined whether the
problem is serious or not, or whether the situation hasn't
corrected itself. In a case like this, the code is registered and
will be displayed if requested, but the "check engine" light will
I'm still learning how this device interacts with the car's
computer, and I'm getting two confusing responses now with my own
car, so I can't comment further until I get this resolved and
know more. I'm still interested in knowing what the difference is
between code readers, which are somewhat affordable, and scan
tools, which are costly professional tools.
