OBD DRIVE MODE [PCM (WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5))]

id0102sc815800

• 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 (WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5))].)

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

1. Start the engine and warm it up completely.

2. Verify all accessory loads (A/C, headlights, blower fan, rear window defogger) are off.

3. Drive the vehicle as shown in the graph.

*1 :Accelerate to 90 km/h {56 mph} within 20 s in D position (ATX)/5th gear (MTX).

*2 :MTX: Within 15 s, accelerate to 24 km/h {15 mph} in the 3rd gear and continue accelerating to 1,750—1,850 rpm, then shift to the 5th gear./ATX: Accelerate to 1,750—1,850 rpm within 15 s.

4. To verify the completion of the drive mode, stop the vehicle and display the [Mode 1 Powertrain Data] of the ON-BOARD DIAGNOSTIC (OBD) TEST MODES using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5))].)

• If the drive mode has been completed, [***_EVAL] or [***RDY] (each system completed) of the PID [***SUP] (with/without support for each system monitor) 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.
