If any DTCs are displayed, perform troubleshooting according to the corresponding DTC
inspection.

5. After completion of repairs, clear all DTCs stored in the PCM, while referring to "AFTER REPAIR

PROCEDURE".

OBD-II DRIVE MODE [MZI-3.7]



The following procedure is designed to execute and complete the OBD-II monitors and to clear the DTC
P1000.



To complete a specific monitor for repair verification, follow Steps 1 through 4, then continue using the
steps indicated by the appropriate monitor.



The Drive Mode is performed using the M-MDS.

CAUTION:



While performing the Drive Mode, always operate the vehicle in
a safe and lawful manner.



When the M-MDS is used to observe monitor system status
while driving, be sure to have another technician with you, or
record the data in the M-MDS using the PID/DATA MONITOR
AND RECORD function and inspect later.

NOTE:



If the OBD-II system inspection is not completed during the Drive
Mode, the following causes are considered:



The OBD-II system detects a malfunction.



The Drive Mode procedure is not completed correctly.



Disconnecting the battery will reset the memory. Do not disconnect
the battery during and after Drive Mode.



The M-MDS can be used at anytime through the course of the Drive
Mode to monitor the completion status. Monitoring can be done by
viewing the ON BOARD SYSTEM READINESS menu.



Most OBD-II monitors will complete more readily using a "steady
foot" driving style during cruise or acceleration. Operating the
throttle in a "smooth" fashion will minimize the time required for
monitor completion.



The fuel tank level should be between 1/2 and 3/4 full with 3/4 full
being the most desirable.



The evaporative emission system monitor can only operate during
the first 30 min of the engine operation. When executing the
procedure for the evaporative emission system monitor, remain in
part throttle position and drive in a smooth fashion to minimize "fuel
slosh".



When bypassing the EVAP soak times, the PCM must remain
powered (ignition switch to the ON position) after clearing the

Preparation



Connect the M-MDS to the DLC-2.



Turn the ignition switch to the ON position
(Engine off).



Turn the ignition switch off then to the ON
position, (Engine off).



Select the appropriate vehicle and engine
qualifier.



Clear the continuous DTCs and reset the emission
monitors information in the PCM.

NOTE:



To bypass the EVAP soak timer (normally 6
hours), the PCM must remain powered after
clearing the continuous DTCs and resetting the
emission monitors information in the PCM.

NOTE:



The following events occur when the
continuous DTCs and the emission
monitors information is cleared from the
PCM:



Clears the number of DTCs and the
DTCs.



Clears the freeze frame data.



Clears the diagnostic monitoring
test results.



Clears the status of the OBD-II
system monitors is reset.



Sets DTC P1000.

Bypasses the engine soak
timer. Resets the OBD-II
monitor status.



Start the engine without turning the ignition
switch off.



Idle the engine for 15 s.



Drive at 64 km/h {40 mph} until the ECT is
76.7°C {170°F} or more.

NOTE:



When the IAT is not within 4.4-37.8°C {40-100°
F} or the altitude is above 2,438 m {8,000 ft} ,
