OBD DRIVE MODE [MZR 1.8, MZR 2.0, MZR 2.5]

id0102f4815800

•  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 01 (PCM Adaptive Memory Produce Drive Mode)
―  Mode 03 (A/F Sensor Heater, HO2S Heater, A/F Sensor, HO2S and TWC Repair Verification Drive Mode)
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 detected a malfunction.
―  The Drive Mode procedure was not completed correctly.
•  Disconnecting the battery will reset the memory. Do not disconnect the battery during and after the 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.

Mode 01 (PCM Adaptive Memory Produce Drive Mode)

1.  Start the engine and warm it up completely.

2.  Verify that all accessory loads (A/C, headlights, blower fan, rear window defroster) are off.

3.  Perform no load racing at the engine speed of 2,800—3,200 rpm for more than 30 s.

4.  Idle the engine for more than 30 s after the cooling fan stopped.

5.  Switch the ignition to off.


Mode 03 (A/F Sensor Heater, HO2S Heater, A/F Sensor, HO2S and TWC Repair Verification Drive Mode)


MZR 1.8/MZR 2.0 (MTX)

1.  Perform the Mode 01 first.

2.  Start the engine and warm it up completely.

3.  Verify that all accessory loads (A/C, headlights, blower fan, rear window defroster) are off.

4.  Drive the vehicle as shown in the graph; first drive in zone O, then A or B, followed by C or D, finally E, F or G. The driving condition before driving at constant speed is not specified.
