OBD-II DRIVE MODE[L3 WITH TC]
• Using the OBD-II drive mode, the 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 the specific drive mode and single drive mode.
• For the 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.
— EGR system
— Oxygen sensor (HO2S)
— Oxygen sensor heater
— Catalytic converter (TWC)
— Fuel, misfire and evaporative (EVAP) system
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
• Vehicle speed and engine speed detected by the PCM may differ from that indicated by the speedometer
and tachometer. Use the M-MDS 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 the 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.
• The OBD monitoring status can be confirmed with the ignition switch operation. During KOEO, the MIL
illuminates for a fail-light inspection for approx. 17 s. The OBD monitoring status is confirmed after the
fail-light inspection.
— If all of the diagnosis is completed even one time, the MIL will continue to illuminate.
— If all of the diagnosis is not completed, the MIL flashes for approx. 7 s, and then it illuminates until the
engine is started.
