Operation CHARM: Car repair manuals for everyone.

History

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