id0102b7815800

• Performing the Drive Mode inspects the OBD system for proper operation and must be performed to ensure that no additional DTCs are present.

• During the Drive Mode, the following systems are inspected:

― A/F sensor heater

― HO2S heater

― A/F sensor

― HO2S

― TWC

― Fuel system and Misfire

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 system inspection is not completed during the Drive Mode, the following causes are considered:

― The OBD system detected a malfunction.

― The Drive Mode procedure was not completed correctly.

• Disconnecting the battery will reset the memory. Do not disconnect the battery during and after the 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.

Mode 3 (A/F sensor heater, HO2S heater, A/F sensor, HO2S, and TWC Repair Verification Drive Mode)

1. Perform the Mode 1 first.
