APDTY 115444 is a brand-new steering wheel clock spring (spiral cable) for 2003–2008 Toyota Corolla and Toyota Matrix. It restores the electrical connection between the steering column and the steering-wheel controls — including the driver airbag, horn, and cruise/audio switches. It replaces Toyota numbers 84306-02110 and 84306-52060, plus interchange numbers 525-402, CSP192, CLS292, and SK525402.
Key Takeaways
- What it is: the SRS clock spring / spiral cable that keeps steering-wheel wiring connected as the wheel turns.
- What it can address: an illuminated airbag/SRS light, an inoperative horn, or non-working cruise/audio steering-wheel buttons caused by a broken clock spring — after proper diagnosis.
- Fits: 2003–2008 Toyota Corolla and 2003–2008 Toyota Matrix (verify against the APDTY chart and your original part number).
- Safety: this is an airbag (SRS) component. Follow factory SRS service procedures and disable the system before working near the airbag.

What does a steering wheel clock spring do?
A clock spring (also called a spiral cable) is a coiled ribbon of wiring inside the steering column that keeps electrical connections intact while the steering wheel rotates left and right. It carries the circuits for the driver airbag, horn, and often the cruise-control and audio switches on the wheel. Because the wheel turns but the wiring must stay connected, the ribbon winds and unwinds inside the housing. Over time that ribbon can wear or break, interrupting one or more of those circuits — which is why a single failed clock spring can trigger several unrelated-seeming symptoms at once.
What are the symptoms of a failed clock spring?
A broken or worn clock spring may cause:
- An illuminated airbag / SRS warning light
- A horn that does not work from the steering wheel
- Cruise-control or steering-wheel audio buttons that stop working
- Intermittent operation that changes as the wheel is turned
- A stored SRS trouble code for the driver airbag circuit
These symptoms can also come from other SRS, horn, or switch faults. A clock spring may help when the fault is traced to the spiral cable itself — but proper diagnosis with a capable scan tool and factory service information is required first.

Are there trouble codes for a bad clock spring?
Often yes — a broken clock spring can set an SRS/airbag trouble code stored in the airbag control module, and the SRS warning light will usually be on. However, a code points to a circuit or system, not automatically to one failed part. The airbag system must be diagnosed with a scan tool capable of reading SRS codes and with factory service information. Do not assume the clock spring is the cause until the driver-airbag circuit has been properly tested.
How is APDTY 115444 installed?
This is a general overview only — clock spring replacement involves the airbag system and must follow the vehicle's factory SRS service procedure.
- Follow SRS safety steps. Turn the wheel to center, turn off the ignition, disconnect the battery, and wait the manufacturer-specified time before working near the airbag.
- Remove the driver airbag module per factory procedure and set it aside face-up in a safe location.
- Remove the steering wheel with the wheels straight and the clock spring centered.
- Replace the clock spring, keeping the new unit centered/locked per its instructions.
- Reassemble the wheel and airbag, torque fasteners to factory spec, reconnect the battery, and clear codes with a scan tool.
- Verify the SRS light goes out and the horn, cruise, and audio controls work.
Important safety warning
APDTY 115444 is a supplemental restraint system (SRS) component. Improper handling of airbag components can cause accidental deployment and serious injury. This work should be performed by someone familiar with SRS service, using the factory procedure and a scan tool that can read and clear airbag codes. If you are not equipped to service the airbag system safely, have the part installed by a qualified technician.
Frequently asked questions
What does APDTY 115444 replace?
It replaces Toyota clock spring numbers 84306-02110 and 84306-52060, and interchanges with 525-402, CSP192, CLS292, and SK525402 on compatible 2003–2008 Corolla and Matrix models.
Will APDTY 115444 turn off my airbag light?
It can, if the light is caused by a failed clock spring in the driver-airbag circuit and the code is cleared after replacement. The SRS system must be diagnosed first — the light can also be caused by other faults.
Does it fix the horn and cruise buttons too?
If those circuits failed because of the broken clock spring, replacing it can restore them. If the switches or other wiring are at fault, those must be addressed separately.
Do I need to program APDTY 115444?
No programming is typically required for the clock spring itself, but SRS codes should be cleared with a scan tool after installation, and the new unit must be installed centered.
Is this an airbag part?
Yes. The clock spring carries the driver-airbag circuit and is part of the SRS. Follow factory airbag safety procedures during installation.
Restore your Corolla or Matrix steering-wheel controls
A failed clock spring can light the airbag warning and knock out the horn and steering-wheel controls all at once. APDTY 115444 gives 2003–2008 Toyota Corolla and Matrix owners a brand-new direct replacement for Toyota 84306-02110 / 84306-52060. Verify your year, trim, and original part number, follow factory SRS procedures, and diagnose the airbag system before ordering.
