OBD-II Drive Mode [SKYACTIV-G 2.0]: Notes
- Using the OBD-II Drive Mode, the monitoring item requested by OBD-II regulations can be easily diagnosed.
- Performing the Drive Mode inspects the OBD-II system for proper operation and must be performed to ensure that no additional DTCs are present.
- The OBD-II Drive Mode is divided into the specific Drive Mode and single Drive Mode.
- For the specific Drive Mode, specified Drive Modes have been set for each individual monitoring item requested by OBD-II regulations, and they can be diagnosed individually. For the single Drive Mode, the entire monitoring item requested by OBD-II regulations can be diagnosed.
- The following modes are in the specific Drive Mode. The applicable system is diagnosed by driving in the following Drive Modes.
- Mode 03 (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)
- The following systems are diagnosed with the single Drive Mode.
- Oxygen sensor (A/F sensor, HO2S)
- Oxygen sensor heater (A/F sensor heater, HO2S heater)
- Catalytic converter (TWC)
- Evaporative (EVAP) system
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-II system inspection is not completed during the Drive Mode, the following causes are considered:
- The OBD-II 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 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.
- 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.
