Product Description
Engineered to Hyundai Mobis OEM standards, the 93490-2M300 is a steering wheel clock spring (spiral cable) for Hyundai and Kia vehicles. It serves as a stable power transmission component between the steering column and steering wheel, delivering continuous electrical signals for the airbag, horn, multi-function buttons and steering angle sensor. With high-flexibility internal wiring and a dustproof sealed housing, it maintains consistent signal transmission during frequent left and right steering rotation, suitable for commercial maintenance and component replacement for business buyers.
Specification | Details |
OE Number | 93490-2M300 |
Product Name | Clock Spring / Spiral Cable / Steering Angle Sensor |
Material | High toughness insulating plastic + reinforced copper wire |
Features | Airbag horn multi-function control integrated |
Original Standard | Hyundai Mobis OEM Standard |
Fitment | Hyundai Kia Compact Mid-size Cars |
The component uses high-purity oxygen-free copper wiring for signal delivery. The wiring structure supports continuous signal transfer during steering wheel rotation, supporting responsive operation of the airbag, horn and steering wheel control buttons.
The insulating material features heat and low temperature resistance. It reduces risks of wire aging, cracking and short circuit, and adapts to temperature changes in the engine compartment environment.
The unit adopts a fully enclosed dustproof and waterproof shell that prevents contamination from dust, moisture and oil. The sealed structure reduces internal friction and supports extended service life.
Produced in line with OEM production standards, the component maintains stable resistance values. It reduces occurrences of airbag fault alarms and steering system failures, supporting driving safety.
The component follows original equipment size and wiring interface specifications. It is compatible with original vehicle plugs, requires no programming, and supports direct replacement to reduce maintenance costs for commercial workshops.

Configuration note: Compatible with vehicles equipped with audio control, Bluetooth and cruise control, excluding vehicles with steering wheel heating function.
A continuously lit airbag indicator with fault codes B1346 / B1347 stored in the SRS module is typically caused by a snapped internal spiral copper ribbon inside the clock spring, which cuts off the airbag circuit. Disconnect the battery negative terminal and wait 10 minutes to discharge SRS residual power. Remove the steering wheel to inspect the spiral cable for cracks or burnt traces. Install a new 93490-2M300 aligned to the neutral center mark, then clear fault codes and verify the light turns off after startup.
No horn sound or intermittent operation at specific steering angles stems from partial fracture or oxidized contact points on the horn signal ribbon inside the clock spring. Test the horn power supply and ground wire to rule out external circuit failure. Replace the 93490-2M300 if the horn circuit loses continuity during full steering rotation, and lock all connectors with an audible click after installation.
Unresponsive or intermittent audio, Bluetooth and cruise control buttons during steering rotation are caused by worn or broken spiral wires dedicated to multi-function control channels. Read signal data via an OBD scanner to confirm circuit interruption from the clock spring. Replace the complete 93490-2M300 assembly, as the internal spiral ribbon cannot be repaired separately. Test all control functions after installation.
Flickering airbag lights, cut-out horns and non-functional buttons at full steering lock usually result from the clock spring not being centered to neutral position during installation, leading to over-stretched spiral ribbon. Remove the steering wheel and reset the clock spring to factory neutral lock position. Avoid over-rotating the clock spring housing without the steering wheel mounted to prevent excessive twisting damage.
Immediate fuse blow after ignition is caused by damaged insulation of internal spiral wires, which creates a short circuit between signal lines. Unplug the clock spring connector and replace the fuse to confirm the short-circuit source. Fit a new 93490-2M300, ensure no wires get pinched during steering column assembly, then check fuse status after installation.
Scraping or clicking noise from the steering column during rotation usually comes from a deformed plastic housing or twisted spiral ribbon rubbing against internal structures. Dismantle the steering column trim to locate the noise source. Replace the defective 93490-2M300 unit directly, as lubrication cannot resolve internal ribbon friction noise.
Common causes include misaligned neutral center position, bent/loose connector pins, or SRS fault memory triggered by battery connection during disassembly. Always disconnect the battery and wait 10 minutes before removal. Align the yellow center marker strictly to the neutral lock position, fully insert all wiring plugs, clear fault codes and perform full steering rotation tests.
Installing mismatched part numbers can cause loss of audio or Bluetooth functions. The 93490-2M300 is designed exclusively for vehicles with steering audio and Bluetooth controls, and cannot be cross-replaced with clock springs without corresponding wire channels.
For commercial procurement orders, the minimum order quantity ranges from 500 to 1000 units. Two packaging categories are available: genuine (MOBIS) standard packaging, and aftermarket brand packaging including neutral packaging (the most common option) and custom branded packaging.
