GM Renault Ultrasound Interior Alarm Sensor

This automotive component is an ultrasonic interior alarm sensor, identified by the General Motors (GM) part number 91 166 611 and Renault part number 8200022115. These sensors are designed to detect movement within a vehicle's cabin to trigger an alarm system.

The dual branding on the plastic housing—featuring both the GM logo and the Renault diamond—is characteristic of parts shared between automotive manufacturers during development partnerships. In this specific case, the part was used across several vans produced in a joint venture, including the Renault Trafic, Vauxhall/Opel Vivaro, and Nissan Primastar. Because these vehicles were assembled in various European locations using a global supply chain, manufacturing typically occurs in multiple countries across Europe and Asia.

General Motors is an American multinational headquartered in Detroit, while Renault is a French multinational. While GM sold its European brands (Opel and Vauxhall) to the PSA Group (now Stellantis) in 2017, the intellectual property and heritage of parts produced under the GM era remain linked to their original engineering origins.
