4. When temperature entry conditions are met, increase engine speed above idle using the throttlepedal for a minimum of five minutes. Ensure the “Engine State” parameter in the screenindicates “Torque Demand.” You can use the free running timer located at the bottom right ofthe screen to monitor the time above idle.5. When the five minute time is reached, decrease engine speed to idle.NOTE:Do not allow the engine to stay at idle for more than five minutes or the test will need to be repeated.6. Turn ignition OFF.7. Allow system to bleed down for approximately 10 seconds.8. Turn ignition ON.9. Reconnect to MCM and CPC.10. Read the value for “HP Leak Actual Value.”[a] If the value is between 0.500 and 1.800, the system leakage is acceptable.
[b] If the value is less than 0.500 or greater than 1.800, the system leakage is unacceptableand should be checked.11. At this point “HP Learned Leak Counter” or “HP Leak Counter” should increase by one (1).[a] If the “HP Learned Leak Counter” did not increase but the “HP Leak Counter” did, theleakage in the system is above the threshold. Repair the system and rerun the test.[b] If the “HP Learned Leak Counter” and the “HP Leak Counter” did not increment, entryconditions were not met. Go to step 3.[c]If the “HP Learned Leak Counter” did increase, complete the relearn process one moretime. If the second learn test also passes, release the truck to the customer. The remainingeight “learns” will be completed on the road. Go to step 3.
