EVAP System Repair Verification Drive Mode
Note
• If “EVAP System Repair Verification Drive Mode” cannot be performed (it is impossible to drive the vehicle
under this drive mode condition), perform the EVAP system test procedure as an alternative.
1. Verify that all of the following PIDs are within the following specifications. All PIDs must be within specifications
before the engine is started to initiate the EVAP system test.
• BARO: above 72.2 kPa {542 mmHg, 21.3 inHg}
• IAT: 5— 35 °C {41— 95 °F}
• FTL: 15— 85%
• B+: above 10.9 V
2. Clear the DTC from the PCM memory using the M-MDS.
3. Turn the ignition switch off.
4. Leave the vehicle for 5 hours or more.
5. Start the engine and idle it for more than 5 min.
6. Drive the vehicle at an engine speed of 65— 80 km/h {40— 50 mph} for more than 5 min.
7. Stop the vehicle and the turn ignition switch off.
8. Leave vehicle as it is for 5.5 hours or more.
9. Start the engine.
10. Access the ON BOARD SYSTEM READINESS to verify the OBD monitoring status.
• If completed, the OBD monitoring status items change from non-completed to completed.
• If not completed, turn the ignition switch off then go back to Step 1.
11. Access the DIAGNOSTIC MONITORING TEST RESULTS to verify the monitor results.
• If detected values are not within specification, the repair has not been completed.
12. Verify that no DTCs are present.
PCM Adaptive Memory Production, EGR, HO2S heater, HO2S, TWC, and EVAP System Repair Verification
Drive Mode
1. Start the engine and warm it up completely.
2. Clear the DTC from the PCM memory using the M-MDS.
3. Verify the following conditions and correct if necessary:
• All accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
4. Verify that all of the following PIDs are within the following specifications. All PIDs must be within specifications
from Step 5 to 6.
• BARO: above 72.2 kPa {542 mmHg, 21.3 inHg}
• IAT: 5— 35 °C {41— 95 °F}
• FTL: 15— 85%
• B+: above 10.9 V
5. With the vehicle stopped, race the engine at the engine speed indicated, and then drive the vehicle as shown in
the graph. The driving conditions before driving at constant speed are not specified. If possible, monitor RPM
PID for engine speed during this procedure.
