Mazda CX-9 Grand Touring. Manual — part 221
Prep for Monitor
Entry
4
Is the IAT within 4.4-37.8°C {40-100°F}?
If not within the specification, complete the
following steps but, note that step 13 will
be required to "bypass" the EVAP monitor.
the EVAP monitor will not run.
Engine warm-up and
provides IAT input to the
PCM.
HO2S
5
Cruise at 64 km/h {40 mph} for up to 5 min.
Executes the HO2S
monitor.
EVAP
6
Cruise at 64-89 km/h {40-55 mpr} for 10 min.
NOTE:
To initiate the monitor, the throttle should be at
part throttle, Evaporative Emissions Duty Cycle
must be more than 75%, and FLI must be 15-
85%, and for fuel tanks over 25 gallons Fuel
Level Indicator Input must be 30-85%.
Executes the EVAP
emission monitor.
Catalyst
7
Stop the vehicle and go to traffic conditions.
Include five different constant cruise speeds,
ranging from 32-89 km/h {20-55 mph} over a 10
min period.
Executes the catalyst
efficiency monitor.
CCM (Engine)
8
Stop the vehicle.
Idle the engine for 2 min with the selector lever in
the D range.
Executes the idle air
control portion of the
CCM.
CCM
(Transaxle)
9
Stop the vehicle.
In overdrive, moderately accelerate to 81 km/h
{50 mph} and cruise for 15 s or more.
Stop the vehicle and repeat without overdrive to
64 km/h {40 mph} cruising for 30 s or more.
While at 64 km/h {40 mph} , activate overdrive
and accelerate to 81 km/h {50 mph} and cruise
for 15 s or more.
Stop the vehicle for 20 s or more.
Repeat Step 9 five times.
Executes the transaxle
portion of the CCM.
Misfire and Fuel 10
Stop the vehicle.
Accelerate to 97 km/h {60 mph}.
Decelerate at closed throttle until reaching 64
km/h {40 mph} (no brakes).
Repeat 3 times.
Allows learning for the
misfire monitor.

11
Access the ON BOARD SYSTEM READINESS
to verify the OBD-II monitoring status.

DIAGNOSTIC MONITORING TEST RESULTS [MZI-3.7]
The purpose of this test mode is to confirm the result of OBD-II monitor diagnostic test results. The result
values stored when particular monitor is completed are displayed. If the monitor is not completed, initial
value is displayed.
DIAGNOSTIC MONITORING TEST RESULTS
Check
status items change from non-completed to
completed.
If not completed, go to the next step.
completed.
Pending Code
Check and
EVAP Monitor
Bypass Check
12
Verify that no pending code has been stored. If
any pending code has been stored, perform the
appropriate DTC inspection. (See DTC TABLE
[MZI-3.7].)
Otherwise, return any incomplete monitor.
Perform the "EVAP Monitor Bypass" procedure.
NOTE:
If the EVAP monitor is not completed and
the I AT was out of the 4.4-37.8°C {40-
100°F} range, or the altitude is above
2,438 m {8,000 ft} , the "EVAP Monitor
Bypass" procedure must be followed.
Determines if a pending
code is preventing the
clearing of the DTC
P1000.
NOTE:
The DTC P1000
will be stored if
any of the OBD-II
monitors does
not complete.

Bypass
13
Leave the vehicle for 8 h.
Go to Step 2 then perform from Step 2 to 11.
Allows the "bypass"
counter to increment to
two.
