Line 1: ## MID: XXX XXXXXX XX ; Line 5: 1st: Last:
Line 2: PID Description; Line 6: Total#:
Line 3: FMI Description; Line 7: Total Time:
Line 4: |## PID: XXX FMI: XX ; Line 8: Min/Max:
Explanation:
##: Indicates the DDC diagnostic flash code number
|##: Numerical Count of inactive codes
1st: First occurrence of the diagnostic code in engine hours
Last: Last occurrence of the diagnostic code in engine hours
Total#: Total number of occurrences
Total Time: Total engine seconds that the diagnostic code was active
Min/Max: Minimum/Maximum value recorded during diagnostic condition
