General Information
Repairs to the emissions-control systems of a 1996 or newer vehicle
cause the vehicle
‟
s computer (ECU) memory to be cleared. The
vehicle must go through a drive cycle to allow the ECU to perform a
series of tests to ensure that the repair was successful, and before a
state mandated emissions test can be conducted. But how will you
know when it is ready?
With this
code reader
, you don
‟
t have to drive around endlessly and
continuously coming back to the repair shop for retest if all required
tests by the ECU are completed. And you could also do a quick check
of the vehicle to determine if it is ready to receive an emission test
without the hassle of connecting your vehicle to the analyzer or
having to use a complicated scan tool.
In the following cases, this function is especially useful.
You bought a used car and the check engine light had been
cleared to mask potential problems.
You used a
code reader
to clear the DTCs.
Your car has been sent to repair.
