Descrizione

Riferimenti OEM 54354139 e DH991872149. Un originale usato, testato Land Rover clock spring spiral cable — the coiled ribbon connector preserving continuous electrical contact through every degree of steering wheel travel.

The spiral cable — also referred to as a clock spring, squib, or rotary coupler — consists of a precision coiled ribbon connector inside a moulded plastic carrier, positioned at the steering column and wheel hub interface. The ribbon accommodates the full range of steering wheel rotation without breaking any electrical path, supplying power and signals to the driver airbag pyrotechnic squib, the horn, and every control integrated into the steering wheel (cruise, media, telephone, paddle shifters). Its direct role in the airbag firing circuit makes it safety-critical.

Driver airbag or SRS warning light on the instrument cluster — this is the most urgent symptom, indicating the airbag circuit may be broken; horn failure; all steering wheel-mounted controls becoming inactive; a clicking or crunching noise when turning the steering wheel to full lock; or visible physical damage to the ribbon cable.

Safety-critical part. Professional installation is required — the airbag pyrotechnic circuit passes through this unit and incorrect installation can prevent the driver airbag from deploying in a collision. After fitting, all SRS fault codes must be cleared using appropriate diagnostic equipment. Verify the OEM number against your exact vehicle before ordering. 14-day returns accepted on unmodified parts.
