Useful checks before replacing parts
- Measure manual mode signal voltage, reference feed, ground, and continuity while moving the selector through automatic and manual gates.
- Inspect shifter switch contacts, connector terminals, short-to-ground faults, liquid intrusion, and wiring flex points around the console.
- Compare low input status with gear display, manual mode entry, upshift and downshift request data, and range sensor state.
