Maintenance rules allow you to use the Maintenance Items trigger to execute actions automatically based on a value of a maintenance item counter, target count, or target date.
The Maintenance Event trigger differs from the Maintenance Item trigger in that the Maintenance Event fires for each and every cycle while the Maintenance Item trigger fires once for a specific value. For example, suppose you have a Maintenance Item called Oil Change, with a Count Interval of 3000 (so that the oil is changed every 3000 miles). You could set up a maintenance rule using the Maintenance Event that will remind you for every oil change every 3000 miles. Now suppose that the vehicle requires a major servicing at 50,000 miles. You would use the Maintenance Item trigger in a rule to remind you when the Counter value equals 50000.
The Maintenance Item trigger can check for the following conditions for the selected Maintenance Item:
o Is the Counter value greater than the value specified when the rule was configured?
o Is the number of days from the last reset date to the current date greater than the value specified when the rule was configured (Time)?
From this page, you select the maintenance item and values that you want to check.
1. From the Maintenance Item list, select the maintenance item to which this rule applies.
2. Select the condition(s): Counter or Time, or both.
3. Type a value for Counter and/or Time that you want the trigger to check against the current values.
4. Click Next to display the Actions for rule page.
