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.
