The Clock Spring 84306-06140 is a critical safety and convenience component in your vehicle's steering system. It acts as the electrical bridge between the rotating steering wheel and the stationary steering column, ensuring a continuous and reliable connection. This allows your driver's airbag, horn, and steering wheel controls to function flawlessly, regardless of how many times the wheel is turned.
Engineered as a direct replacement for specific Toyota models, this unit is built to strict OEM specifications. It guarantees a precise fit and dependable performance, maintaining the integrity of your vehicle's safety systems.
Key Features
Exact Fit for Toyota Models
- Specifically designed for Toyota vehicles, this clock spring offers a direct bolt-in replacement. No modifications, adapters, or rewiring are required, ensuring a seamless installation process.
01
Reliable Signal Transmission
- Features a high-cycle flexible flat cable that withstands thousands of steering rotations without signal loss. This ensures your airbag, horn, and multifunction buttons remain fully operational at all times.
02
Durable and Heat Resistant
Constructed with high-strength, flame-retardant engineering plastics (PA66) that remain stable under high temperatures and vibrations. The materials are also resistant to dust and moisture, suitable for the under-dash environment.
03
Engineered for Safety
- Includes an internal centering mechanism to prevent the internal cable from over-rotating during installation. This critical feature protects the delicate ribbon cable from damage and ensures safe operation.
04
Rigorous Quality Testing
- Manufactured under ISO/TS 16949 standards. Each unit is tested for rotational smoothness, electrical continuity, and thermal endurance to ensure consistent performance right out of the box.

Structural Composition
1.Core Assembly: A white spiral reel housed within a black engineering plastic casing, containing the wound flat cable that enables continuous rotation.
2.Electrical Connectors:
(1)Vehicle Side: Typically features a multi-pin connector (often white or black) to interface with the vehicle's main harness.
(2)Steering Wheel Side: Includes a dedicated yellow airbag connector (SRS) and additional pins for horn and multifunction buttons.
3.Mounting Base: Integrated clips and screw bosses ensure a secure, vibration-free fit onto the steering column.
4.Centering Mechanism: An internal stop-and-return feature that holds the spring in the neutral position, crucial for safe installation and preventing cable damage.

Installation and Usage Notes
1.Center the Steering Wheel: Before installation, ensure the steering wheel is perfectly centered. Manually rotate the clock spring's inner hub to its neutral position (usually marked by a line or notch) to prevent the internal cable from binding.
2.Handle Connectors with Care: Do not force any electrical connectors. They are designed to click into place smoothly. Forcing them can damage the delicate pins inside.
3.Post-Installation Test: After installation, reconnect the battery and turn the ignition on. Test the following functions:
(1)The horn sounds when pressed.
(2)Steering wheel audio and phone controls respond.
(3)The SRS (airbag) warning light on the dashboard turns off after the system's self-check.
4.Critical Safety Step: Always disconnect the negative terminal of the vehicle's battery and wait at least 15 minutes before beginning work to allow the airbag system's capacitor to discharge and prevent accidental deployment.
