Hello and welcome to justanswer.com
Here is the complete evap readiness monitor. We use the Jag factory tool to assist in doing this since it is part of the drive cycle. I will send over the procedure so you can try your best to run through it.
EVAPORATIVE SYSTEM MONITOR DRIVE CYCLE 1. Ensure that fuel filler cap is fully closed (minimum three clicks).
2. Fuel level > 30% and < 85%.
3. Using WDS, perform ECM DTC Clear (even if no DTCs are flagged).
4. Drive vehicle for a minimum of 2 minutes, and until engine is at normal operating temperature.
5. Using WDS, ensure that the EVAP Canister Purge Valve is operating by observing “PURGE VAPOR MANAGEMENT VALVE – DUTY CYCLE”. If the valve is not active, ECM adaptions have not been learned. Conduct a “green ECM” Drive Cycle as described in Technical Service Bulletin.
6. Drive vehicle to the road where the EVAP System Drive Cycle will be conducted. Stop vehicle and switch OFF the ignition. Leave ignition OFF for 30 seconds, and then restart the engine.
7. Accelerate briskly to 80 km/h (50 mph) ensuring that the engine speed reaches a minimum of 3500 rpm for a minimum of 5 seconds.
8. (0.040-inch EVAP Test) View WDS “PURGE VAPOR MANAGEMENT VALVE – DUTY CYCLE”, “CANISTER CLOSE VALVE – VAPOR RECOVERY SYSTEM”, and FUEL TANK PRESSURE – VAPOR RECOVERY SYSTEM”. Avoiding high engine loads, drive the vehicle steadily between 65 km/h (40 mph) and 100 km/h (60 mph). Avoid driving conditions that will produce excessive fuel movement. WDS should give an indication that the test is active (it may take up to 30 minutes before the test will initialize). When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.
9. (0.020-inch EVAP Test) Continue driving vehicle as explained in Step 8 for an additional 10 minutes.

10. Gently coast the vehicle to a stop. Allow the engine to idle for 2 minutes and view WDS “PURGE VAPOR MANAGEMENT VALVE – DUTY CYCLE”, “CANISTER CLOSE VALVE – VAPOR RECOVERY SYSTEM”, and FUEL TANK PRESSURE – VAPOR RECOVERY SYSTEM”. WDS should give an indication that the test is active. When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.
11. If the 0.020-inch EVAP Test is not activated, the purge system vapor concentration may be too great. To reduce the vapor concentration proceed as follows:
12. Drive the vehicle for an additional 30 minutes avoiding driving conditions that will produce excessive fuel movement. Repeat Step 10. If the 0.020-inch EVAP Test is still not activated, repeat the Drive Cycle from Step 6.
13. Using WDS, check for and clear flagged DTCs
