CODE RETRIEVAL PROCEDURE
¾ Green LED – Indicates that all engine
systems are “OK” and operating normally.
All monitors supported by the vehicle have
run and per-formed their diagnostic testing,
and no trouble codes are present. A zero
will show on the CanScan’s LCD display.
¾ Yellow LED – Indicates one of the
following conditions:
A. A PENDING CODE IS PRESENT – If the
yellow LED is illuminated, it may indicate a
Pending code is present. Check the
CanScan’s LCD display for confirmation. A
Pending code is confirmed by the presence
of a numeric code and the word PENDING
on the CanScan’s LCD display.
B. MONITOR NOT RUN STATUS – If the
CanScan’s LCD display shows a zero
(indicating there are no DTC’s present in the vehicle’s computer memory),
but the yellow LED is illuminated, it may be an indication that some of the
Monitors supported by the vehicle have not yet run and completed their
diagnostic testing. Check the CanScan’s LCD display for confirmation.
¾ Red LED – Indicates there is a problem
with one or more of the vehicle’s systems.
The red LED is also used to indicate that
DTC(s) are present (displayed on the
CanScan’s screen). In this case, the
Multifunction Indicator (Check Engine)
lamp on the vehicle’s instrument panel will
be illuminated.
¾ DTC’s that start with “P0”, “P2” and some
“P3” are considered Generic (Universal).
All Generic DTC definitions are the same on all OBD2 equipped vehicles.
The CanScan automatically displays the code definitions for Generic
DTC’s.
¾ DTC’s that start with “P1” and some “P3”
are Enhanced (Manufacturer specific)
codes and their code definitions vary with
each vehicle manufacturer. When an
Enhanced (Manufacturer specific) DTC is
retrieved, the LCD display shows a list of
vehicle manufacturers. Use the UP and
DOWN buttons, as necessary, to highlight the appropriate manufacturer,
then press the ENTER/FF button to display the correct code definition
