Supersedes Technical Service Bulletin Group 90 number 09-11 dated August 14, 2009 for reasons listed below.

CONDITION



After performing service work and resetting the Service Display using Vehicle Self Diagnosis, the service reminder reappears immediately or soon



after the customer leaves the dealership.



TECHNICAL BACKGROUND



Worldwide, service items are divided into two groups: those triggered by accrued mileage and those triggered by elapsed time.



For customer convenience, North America groups these two kinds of service items together at our published service intervals. For example, both



time-related and mileage-related service items are performed at the 15K service. This practice reduces the how often the customer must visit the



dealer for routine maintenance.



In some other parts of the world, these two categories of service items are treated individually, and are therefore reset individually via separate



adaptation channels in the instrument cluster. However, attempting to reset the Service Display via Vehicle Self Diagnosis introduces the risk of not



resetting all the necessary adaptation channels for North America.



PRODUCTION SOLUTIONS



Not applicable.



SERVICE



When resetting the service interval display, use the Service Work function in Guided Functions or Guided Fault Finding. This method will ensure



that all necessary adaptation channels are reset.



WARRANTY
