Useful checks before replacing parts
- Check manual control signal voltage, ground, open circuits, short-to-voltage faults, connector fit, and switch state transitions.
- Inspect steering-wheel or shifter wiring, clock spring paths, console connectors, spilled-liquid damage, and recent trim or shifter work.
- Compare high input behavior with manual mode entry, upshift and downshift requests, and gear display state.
