Useful checks before replacing parts
- Monitor manual control input values while operating every manual shift control and compare them with module mode and gear display data.
- Inspect switch resistance or voltage ladder values, connector corrosion, spilled-liquid damage, wiring flex points, and ground stability.
- Check whether the fault appears in one direction, one selector gate, after moisture exposure, or during repeated manual shifts.
