Distance traveled since diagnostic trouble codes cleared CLR_DISTSAE J1979Confirmed
Distance accumulated since DTCs were cleared (via an external test equipment or possibly, a battery disconnect). This parameter is not associated with any particular DTC. It is simply an indication for inspection/maintenance, of the last time an external test equipment was used to clear DTCs. If greater than 65,535 km have occurred, will remain at 65,535 km and not wrap to zero.
Pelican can show this parameter as the distance since trouble codes were cleared.
