Service Bulletin 09-086 for Display Shows Higher MPG Than Actual

[awptickes]

Service Bulletin 09-086, issued November 18, 2009.

SYMPTOM
The information display shows the fuel mileage to be 10 to 15 percent higher than the customer’s actual calculated mileage.
NOTE: Verify that the customer has correctly calculated the mileage by dividing the miles driven by the number of gallons used.

PROBABLE CAUSE
The PGM-FI software bases its fuel calculations on an incorrect data set.

CORRECTIVE ACTION
Update the PGM-FI software with the HDS.



I'll let everyone know what's up afterwards.
