Mazda service manuals
The purpose of the OBD-II Drive Cycle is to execute the monitors and identify any concerns
with the system. The DTC P1000 code is erased when all monitors have been completed
during the Drive Cycle.
IMPORTANT:
Strict observance of posted speed limits and attention to driving conditions are mandatory
when performing the Drive Cycles.
The scan tool may be used to observe the status of each monitor at the completion of the
OBD-II Drive Cycle. The completion status of the exhaust gas recirculation (EGR), heated
oxygen sensor (HO2S), catalyst efficiency and evaporative emission (EVAP) monitors can be
monitored during the OBD-II Drive Cycle by viewing the Readiness Monitors on the scan tool.
Risk of airbag deployment
• At no time place the scan tool or any other object between the airbag and a person!
In the case of airbag deployment, an object near the expanding airbag may be
propelled at high speed and become a projectile capable of causing serious injury,
death, or property damage.
Accidental airbag deployment can cause death or serious injury.
Drive Cycle Recommendations
• If the OBD-II Readiness Monitor selection is not available for any given model, use the
OBD-II Generic Selection.
• Most monitors complete more readily using a “steady foot” driving style during cruise or
acceleration. Fuel tank level must be between 1/4 and 3/4 full with 3/4 being the most
desirable.
• The Evaporative Monitor can only operate during the first 30 minutes of engine operation.
When executing the procedure for this monitor, stay in part throttle mode and drive in a
smooth fashion to minimize fuel slosh.
• If completed, the OBD-II Readiness Monitor flags change from NOT DONE to READY.
• After Drive Cycle completion, check for Codes and also Pending Codes in OBD-II
Generic “Codes and Data” Menu.
Use the following procedures for all models except the 1996–97 626/MX6 with 2.0L engine
and automatic transmission, 1996–2004 B-series trucks, and 2001–04 Tribute:
• See “MODE 6—EVAP System Repair Verification Drive Mode” on page MA12. for 1996–
97 626/MX6 2.0L models.
• See “1996–2005 B-Series Trucks (All), 2001–05 Tribute” on page MA17. for 1996–2004
B-Series trucks and 2001–04 Tribute.

Using the OBD-II drive mode, a monitoring item requested by OBD-II regulations can be
easily diagnosed. Performing the Drive Mode inspects the OBD-II system for proper
operation and must be performed to ensure that no additional DTCs are present. The OBD-II
drive mode is divided into Specific Drive Mode and Single Drive Mode:
• For Specific Drive Mode, specified drive modes have been set for each individual
monitoring item requested by OBD-II regulations, and they can be diagnosed individually.
• For the Single Drive Mode, the entire monitoring item requested by OBD-II regulations
can be diagnosed.
The following modes are in the Specific Drive Mode. The applicable system is diagnosed by
driving in the following drive modes:
•
•
•
•
PCM Adaptive Memory Produce Drive Mode
EGR System Repair Verification Drive Mode
HO2S heater, HO2S, and TWC Repair Verification Drive Mode
EVAP System Repair Verification Drive Mode
The following systems are diagnosed with the Single Drive Mode:
•
•

IMPORTANT:
While performing the Drive Mode, always operate the vehicle in a safe and lawful manner.
When observing monitor system status while driving, be sure to have another technician with
you, or record the data and inspect later.
i
NOTE:
Vehicle speed and RPM detected by the PCM may differ from that indicated by the
speedometer and tachometer. Use the DATA PID to monitor vehicle speed.
If the OBD-II system inspection is not completed during the Drive Mode, the following causes
are considered:
•
•
•
•
The OBD-II system detects malfunction.
The Drive Mode procedure is not completed correctly.
Do not disconnect the battery after the Drive Mode, this will reset the memory.
The scan tool can be used at anytime through the course of the Drive Mode to monitor the
completion status by viewing ON BOARD SYSTEM READINESS.
• The OBD monitoring status can be confirmed with the ignition key operation. During
KOEO, MIL illuminates for a fail-light inspection for approximately 17 seconds. The OBD
monitoring status is confirmed after the fail-light inspection:
– If all of the diagnosis is completed even once, the MIL will continue to illuminate.
