Single Drive Mode (PCM Adaptive Memory Produce, EGR System Repair Verification, HO2S heater, HO2S, TWC, and EVAP System Verification Drive Mode)

With rear HO2S model 

1. Start the engine and warm it up completely.
2. Clear the DTC from the PCM memory using the WDS or equivalent.
3. Verify the following conditions and correct if necessary:
   • All accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
   • Initial ignition timing and idle speed are within the specification.
4. Verify that all of the following PIDs are within the following specifications. All PIDs must be within specifications from Step 5 to Step  6.
   • BARO: more than 72.2 kPa {541 mmHg, 21.2 inHg} 
   • IAT: 5-35 °C {41-95 °F} 
   • FTL: 15-85 
   • B+: 10.9-14.6 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.

6. Stop the engine.
7. Access ON BOARD SYSTEM READINESS menu of GENERIC OBD-II FUNCTION to verify the OBD monitoring status.
   • If completed, all of the OBD monitoring status items change from non-completed to completed.
   • If not completed, turn the ignition switch off, then perform the applicable specific drive mode for any monitoring item that was not in the detection condition.
8. Access DIAGNOSTIC MONITORING TEST RESULTS menu of GENERIC OBD-II FUNCTIONS to verify the monitor results.
   • If detected values are not within specification, repair has not been completed.
