CAUTION:

NOTE:

Mode 01 (PCM Adaptive Memory Production Drive Mode)

1. Start the engine and warm it up completely.
2. Verify the following conditions and correct if necessary:
3. Perform no load racing at the engine speed shown in the graph, then idle the engine for more than 60 s after the cooling fan has stopped. If possible, monitor RPM PID for engine speed during this procedure.

Mode 02 (EGR System Repair Verification Drive Mode)

1. Perform “PCM Adaptive Memory Production Drive Mode” first.
2. Verify all accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
3. Drive the vehicle as shown in the graph.

4. Stop the vehicle and access ON BOARD SYSTEM READINESS menu of GENERIC OBD-II FUNCTION to verify the OBD monitoring status.
5. Access DIAGNOSTIC MONITORING TEST RESULTS menu of GENERIC OBD-II FUNCTIONS to verify the monitor results.
6. Verify no DTCs are available.

Mode 03 (HO2S heater, HO2S, and TWC Repair Verification Drive Mode)

1. Perform “PCM Adaptive Memory Production Drive Mode” first.
2. Verify all accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
3. Drive the vehicle as shown in the graph. The driving conditions before driving at constant speed are not specified.

4. Stop the vehicle and access ON BOARD SYSTEM READINESS menu of GENERIC OBD-II FUNCTION to verify the OBD monitoring status.
5. Access DIAGNOSTIC MONITORING TEST RESULTS menu of GENERIC OBD-II FUNCTIONS to verify the monitor results.
6. Verify no DTCs are available.

Mode 06 (EVAP System Repair Verification Drive Mode)

NOTE:

1. Verify that all of the following PIDs are within the following specifications. All PIDs must be within specifications before engine is started to initiate the evaporative system test.
2. Clear DTC from PCM memory using M-MDS.
3. Start the engine and idle it for more than 10 s, then turn the ignition switch off.
4. Leave vehicle for 5 hours or more.
5. Start the engine and idle 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 turn the 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.
11. Access the DIAGNOSTIC MONITORING TEST RESULTS to verify the monitor results.
12. Verify no DTCs are available.

Single 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:
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.
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.
