2008-09: MAZDA5: 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 02 (EGR System Repair Verification Drive Mode)
- Mode 03 (HO2S heater, 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.
- EGR system
- Oxygen sensor (HO2S)
- Oxygen sensor 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 MIL illuminates for a fail-light inspection forapprox. 17 s
. The OBD monitoring status is confirmed after the fail-light inspection.
- If all of the diagnosis is completed even one time, the MIL will continue to illuminate.
- If all of the diagnosis is not completed, the MIL flashes forapprox. 7 s
, and then it illuminates until the engine is started.
