- Diagnostics menu: Vehicle Info (VIN/cal/ECU), Emissions Readiness (I/M
monitors + MIL -> pass/fail), Freeze Frame (snapshot + capturing DTC).
All routed through the scheduler one-off path; dialogs, no docked panels.
- New Trip / Performance view (View menu, center page): live + average MPG,
trip distance/fuel/time, and 0-60 / 1/4-mile timers. The controller keeps
SPEED + MAF polled in the background and feeds TripComputer/PerformanceMeter
every tick, so trips accumulate regardless of the active view. Honest MAF
caveat shown for speed-density/diesel vehicles.
Validated headless against MockLink: VIN dialog, readiness dialog, freeze-frame
dialog, and the live trip page (28.8 mpg / distance accruing). All tests pass.
