History

This selection displays only the DTCs that are stored to the control module's history memory. The history memory will not display type B DTCs that have not requested the MIL. The history memory will display all type A and type B DTCs that have the MIL and have failed within the last 40 warm-up cycles. In addition, the history memory will display all type C DTCs that have failed within the last 40 warm-up cycles.
