Passenger Seat Occupancy Sensor Diagnostic Bypass for BMW E36 E46 E39 E53 65778367242

Product Overview

This two-wire passenger-seat occupancy sensor emulator is an aftermarket diagnostic plug for compatible BMW seat-mat circuits. It substitutes an occupied-seat signal when used with the matching system. The compact black housing has a green two-contact connector insert and a locking tab, as shown in the product photos.

Product Details

• One compact plug-in occupancy emulator
• Green two-contact connector insert with black locking housing
• For matching two-wire seat-mat circuits and SBE control electronics
• Simulates an occupied-seat signal; does not restore actual occupant detection
• No separate seat-belt warning simulator is included

Fitment and Compatibility

Selected BMW E36, E46, E38, E39 and E53 applications with the matching two-wire passenger-seat occupancy sensor circuit and SBE control electronics.

Match the connector, two-wire sensor type and original restraint-system configuration. Chassis, trim level or an airbag warning light alone does not establish compatibility.

Compare the original connector, pin arrangement and locking features with the photos before ordering. Have a BMW-capable SRS diagnostic check performed to identify the fault. This plug will not resolve unrelated airbag, buckle-switch, wiring or control-unit faults.

System Reference

Photo Guide

The first five images show the emulator plug supplied. The remaining images show it connected to existing SBE control electronics as an application example. The larger labeled SBE module and its harness are shown for identification only and are not included.

Important Use and Installation Information

For diagnostic/off-road use only. An occupied-seat signal can cause the passenger airbag to remain enabled even when the seat is empty. This emulator does not distinguish an adult from a child or child restraint and is not a repair of the original occupancy mat. Do not place children or child restraints in the front passenger seat while it is installed.

Qualified BMW/SRS diagnosis and installation are recommended. Check for open BMW recalls and the proper repair of the original safety system. Stored faults may require appropriate diagnostic equipment; an extinguished warning lamp alone does not confirm that the restraint system is fully functional.
