12+4 Pin Configuration – For Heated Wheel & Multi-Function Controls
This clock spring features a 12+4 pin connector configuration, providing circuits for:

✅ Airbag (SRS) system – critical safety component
✅ Horn operation
✅ Steering wheel audio, phone, and cruise controls
✅ Heated steering wheel function (requires 4-pin auxiliary connector)

Note: This clock spring does NOT include the steering angle sensor. If your vehicle has stability control (VSC) or driver assist features, the angle sensor must be transferred from your original unit.

Why Your Clock Spring Matters
A faulty clock spring may trigger the airbag warning light, cause horn failure, heated wheel malfunction, or make steering wheel controls unresponsive. Prompt replacement is recommended if any of these symptoms occur.

⚠️ IMPORTANT SAFETY NOTE & INSTALLATION TIPS

Before Installation: Disconnect the battery negative terminal and wait at least 5 minutes for the airbag system to discharge.

Angle Sensor Transfer (if applicable): If your original clock spring has an attached angle sensor, carefully unclip it and mount it onto the new clock spring in the same orientation.

Centering: Ensure front wheels are perfectly straight. The new clock spring comes with a centering clip – do NOT remove this clip until the clock spring is fully installed and the steering wheel is in position. Rotating the clock spring without the clip can damage the internal ribbon cable.

Verification: Always verify that the replacement part matches your original in connector type, 12+4 pin configuration, and physical appearance. Professional installation recommended.

Post-Installation: After installation, verify all steering wheel functions (horn, controls, heated wheel, airbag light) operate correctly.
