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 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.

– If all diagnosis is not completed, the MIL flashes for approximately 7 seconds, and

then illuminates until engine is started.
