What the 93490-3V110 is

The 93490-3V110 Clock Spring is the OEM-specification spiral cable assembly for the first-generation Hyundai Veloster (FS platform) with the 1.6L Gamma GDI/MPI engine, model years 2012 through 2017. Hyundai EPC systems list it as the "Clock Spring Assembly-Steering Wheel".

It carries signals between the stationary steering column and the rotating wheel: horn, audio and cruise buttons, and the driver airbag. A fractured ribbon means an airbag lamp and dead wheel controls.

2026 compliance checklist

• CAN-bus 3.0: Yes. The copper ribbon holds signal integrity up to 5 Mbps CAN FD rates, backward-compatible with the Veloster FS HS-CAN architecture.
• SAS interface: It mates with the factory Steering Angle Sensor module via an OEM-identical optical encoder boss and index pin, so true-zero calibration holds without drift.
• Materials: Polyimide-film insulation rated -40°C to +125°C continuous per SAE J1455 and IEC 60243; gold-plated contacts tested past 10,000 rotation cycles.
• OEM pedigree: 93490-3V110 is the exact Hyundai/Kia number cross-referenced across MOBIS, Hyundai Genuine Parts, and Kia Parts catalogs, sourced through Koeep's verified supply chain.

How the part is built

Ribbon circuit and insulation

The unit is a multi-layer spiral-wound flexible flat circuit (FFC), each trace oxygen-free copper laminated between two polyimide (Kapton-type) dielectric layers. That targets creepage degradation, the failure mode behind intermittent airbag lamps on inferior aftermarket units after 18–24 months of thermal cycling.

Each trace is 0.13 mm², rated 1.5A continuous: enough for horn relay actuation and the 2.0A/2ms squib pulse. IEC 60243-1 applies, minimum 1.5 kV AC breakdown voltage across the ribbon insulation.

Terminals and centering

Gold-flashed beryllium-copper terminals per ASTM B194 replace legacy phosphor-bronze pins and hold contact resistance drift below 5 mΩ across the 3.2-turn lock-to-lock rotation. The ACU watches the SRS squib loop continuously and reads drift as a fault.

The yellow centering lock tab ships present and calibrated. Off-center installation is the number one cause of premature clock spring rupture on FS-platform cars, so an illustrated centering tag comes fixed to the housing. Travel is ±580°, about 3.22 turns lock-to-lock.

Technical specification matrix

Why clock spring quality matters in 2026

Hyundai, Ford, GM, Toyota, and Tesla have moved to centralized domain-controller E/E architectures. On Hyundai-Kia platforms the clock spring is a validated node in the safety-critical data path, carrying the SRS deployment loop, the SCC (Smart Cruise Control) switch matrix ladder, and steering angle sensor CAN messages.

A substandard unit adds micro-ohm intermittents the ACU reads as squib faults, setting persistent B1346/B1347 codes and disabling the SRS.

Hyundai's 2026 TSB database makes clock spring inspection mandatory whenever B1346, B1347, B1448, B1080, C1261, or C1262 is logged after a frontal or side-impact event. The Koeep-supplied 93490-3V110 passes post-repair SRS validation on the first cycle; economy units may need multiple ACU resets.

DTC map for the Veloster FS

The assembly talks to the SRS ECU, the BCM, and the SAS module. The pinout matches Hyundai schematic connectors X101 (12-pin, 0.64 mm terminal series) and X201 (4-pin). The clock spring is a primary or secondary cause of these codes:

• B1346 / B1347: Driver airbag squib 1 circuit, resistance out of range. Ribbon trace continuity failure.
• B1448: Clock spring internal circuit malfunction, caught by the SRS ECU self-test.
• B1080 / B1081: Steering wheel remote control switch circuit (audio/cruise). Auxiliary trace open or short.
• C1261 / C1262: Steering angle sensor signal fault; SAS not calibrated or implausible after replacement.
• U0126 / U0151: Lost communication with the SAS module, a 2026 CAN FD gateway timeout flag.

Installation notes

Disconnect the negative battery terminal and wait at least 3 minutes before removing the driver airbag module. The SRS retains capacitive discharge energy that can deploy the bag if the squib connector shorts during removal.

Work through the 27-step procedure in Veloster service manual section RT-54 (Restraint System: Driver Airbag Module and Clock Spring). Individual trace repair is not permitted, so the unit goes in as a complete assembly. Hyundai parts support for this model runs through at least 2028; Koeep holds buffer stock through 2030.
