Wrong Functions, Random Volume, or Odd Steering-Key Behaviour
If your buttons fire the wrong feature, the steering control map is almost always wrong. Clear the SWC map completely, power-cycle, then learn the keys again in the supplier's documented order only.
Problem
- Your steering buttons trigger the wrong function or act randomly.
Symptoms
- You press volume up and it skips a track instead.
- You press once and it registers as a double.
- You get different behaviour with the engine running and with it off.
Cause
- Double learning or overlapping profiles.
- Resistor ladder tolerance sits out of spec when your vehicle's cold.
Fix Step-by-step
- Clear the SWC map in your headunit completely, then turn the ignition off and back on.
- Make sure only one steering wheel adapter is connected. Unplug any old dongles or adapters you've tried.
- Run the learn sequence again from the start, pressing the buttons in the exact order shown. Don't guess the order.
