The Twin Scan II connects to the four terminal
Deutsch style data link connector on the H-D® wiring
harness and requires a laptop PC for user interface
and data display. You can read and clear diagnostic
trouble codes from the ECM, TSM/TSSM,
speedometer, tach (on models with IM data bus), and
ABS (if equipped). You can view real time engine data
on an instrument panel type display.
