OBD-II Drive Mode

OBD-II DRIVE MODE [MZI-3.7]

- The following procedure is designed to execute and complete the OBD-II monitors and to clear the DTC P1000:00.
- To complete a specific monitor for repair verification, follow Steps 1 through 4, then continue using the steps indicated by the appropriate monitor.
- The Drive Mode is performed using the M-MDS.

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:
- If the OBD-II system inspection is not completed during the Drive Mode, the following causes are considered:

- The OBD-II system detects a 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.
- Most OBD-II monitors will complete more readily using a "steady foot" driving style during cruise or acceleration. Operating the throttle in a "smooth" fashion will minimize the time required for monitor completion.
- The fuel tank level should be between 1/2 and 3/4 full with 3/4 full being the most desirable.
- The evaporative emission system monitor can only operate during the first 30 min of the engine operation. When executing the procedure for the evaporative emission system monitor, remain in part throttle position and drive in a smooth fashion to minimize "fuel slosh".
- When bypassing the EVAP soak times, the PCM must remain powered (ignition switch to the ON position) after clearing the continuous DTCs and relearning emission diagnostic information.
