OBD DRIVE MODE [PCM (SKYACTIV-G 2.5T)]
id0102s8815800
• 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 (EGR System, Variable Valve Timing, A/F Sensor Heater, HO2S Heater, A/F Sensor, HO2S and TWC Repair Verification Drive Mode)
― Mode 06 (EVAP System Repair Verification Drive Mode) (Taiwan)
-
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 OBD monitoring status can be confirmed with the ignition switch operation. During KOEO, the check engine light illuminates for a fail-light inspection for approx. 17 s. The OBD monitoring status is confirmed after the fail-light inspection.
-
― If all of the diagnosis is completed even one time, the check engine light will continue to illuminate.
― If all of the diagnosis is not completed, the check engine light flashes for approx. 7 s, and then it illuminates until the engine is started.
Mode 03 (EGR System, Variable Valve Timing, A/F Sensor Heater, HO2S Heater, 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 89 km/h {55 mph} within 20 s in D position.
*2 :Accelerate to 72 km/h {45 mph} within 15 s in D position.
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 (SKYACTIV-G 2.5T)].)
-
• 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.
Mode 06 (EVAP System Repair Verification Drive Mode) (Taiwan)
-
Note
-
1. Verify that all of the following PIDs are within the following specifications. All PIDs must be within specifications before the engine is started to initiate the evaporative system test.
-
• IAT: 5—35 °C {41—95 °F}
• FLI: 15—85 %
• BARO: Above 72.2 kPa {0.736 kgf/cm2, 10.5 psi}
2. Start the engine and warm it up completely.
3. Clear the DTCs from the PCM memory using the M-MDS. (See CLEARING DTC [PCM (SKYACTIV-G 2.5T)].)
4. Drive the vehicle as shown in the graph.
5. 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 (SKYACTIV-G 2.5T)].)
-
• 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 1 again.
6. Access the DIAGNOSTIC MONITORING TEST RESULTS to verify the monitor results.
-
• If detected values are not within specification, repair has not been completed.
7. Verify that no DTCs are displayed.
