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:

• Mode 1 (PCM Adaptive Memory Produce Drive Mode)

• Mode 2 (EGR System Repair Verification Drive Mode)

• Mode 3 (HO2S heater, HO2S, and TWC Repair Verification Drive Mode)

• Mode 4 (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

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.

NOTE:

i Vehicle speed and RPM detected by PCM may differ from that indicated by speedometer and

tachometer. Use 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 a malfunction.

• The Drive Mode procedure is not completed correctly.
