- Ensure your vehicle is OBD2 compliant. See VEHICLES
COVERED on page 5 for vehicle compliance verification
information.
The FixAdvisor will display a code only if
codes are present in the vehicle's
computer memory. If no codes are
present, the message "No Powertrain
DTCs or Freeze Frame Data presently
stored in the vehicle's computer. Please
visit www.Matco.CarScan.com for repair
videos,
displays.
The FixAdvisor is capable of retrieving
and storing up to 32 codes in memory,
for immediate or later viewing.
16. If a recommended solution for the "priority"
DTC is available, the FIX Assist screen for
the DTC displays. The screen shows re-
commended inspection and repair actions
to correct the malfunction that caused the
DTC to be set.
If a recommended solution for the
"priority" DTC is not available, an
advisory message displays. Press the
DTC/FF button to view Freeze Frame
data for the "priority" DTC.
In OBD2 systems, when an emissions-
related engine malfunction occurs that
causes a DTC to set, a record or
snapshot of engine conditions at the
time that the malfunction occurred is
also saved in the vehicle's computer
memory. The record saved is called
Freeze Frame data. Saved engine
conditions include, but are not limited
to: engine speed, open or closed loop
operation, fuel system commands,
coolant temperature, calculated load
value, fuel pressure, vehicle speed, air
flow rate, and intake manifold pressure.
If more than one malfunction is present that causes more than
one DTC to be set, only the code with the highest priority will
contain Freeze Frame data. The code designated "01" on the
Scan Tool display is referred to as the PRIORITY code, and
Freeze Frame data always refers to this code. The priority
code is also the one that has commanded the MIL on.
Press the DTC/FF button to view retieved codes, beginning with
the "priority" DTC.
