OBD DRIVE MODE [PCM (SKYACTIV-D 2.2)]
id0102j5815800
• 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.
-
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 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.
