id0102t1815800

• Using the OBD Drive Mode, the monitoring item requested by OBD regulations can be easily diagnosed.

• 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:

― Mode 03 (Variable Valve Timing, A/F Sensor, HO2S and TWC Repair Verification Drive Mode)

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 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 anytime during the drive mode course to monitor the completion of the Drive Mode. Conditions can be monitored by viewing the Mode01 Powertrain Data menu. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT CYLINDER DEACTIVATION))].)

Mode 03 (Variable Valve Timing, A/F Sensor, HO2S and TWC Repair Verification Drive Mode)

1. Start the engine and warm it up completely.

4. To verify the completion of the drive mode, stop the vehicle and display the following menu from the M-MDS initial screen. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT CYLINDER DEACTIVATION))].)

(1) Select “Tool Box”.

(2) Select “Powertrain”.

(3) Select “OBD Test Modes”.

(4) Select “Mode 1 Powertrain Data”.

• If the drive mode has been completed, ***_EVAL of the PID ***SUP item indicating Yes changes from No to Yes.

• If the drive mode has not been completed, switch the ignition off and repeat the procedure from Step 3 again.

5. Verify no DTCs are available.
