: Separate fuses for left/right main and dipped beams (F9 through F12). Key Identification & Components
Siemens warranty and safety policies typically state that any alteration, improper installation, or use of unauthorized components voids the warranty and may compromise the safety of the interlocking or power system. Always ensure you are working with the official, English-language version of the manual for the most accurate wiring diagrams. siemens bsm b3 schematic
: Carefully scrape or dissolve the clear protective conformal silicone resin masking the target component connections.
Typically 230V AC or 115V AC, protected by dedicated upstream circuit breakers. Lighting outputs (High/Low beams), side markers, fog light
: Receives a low-current trigger from the ECU and closes the high-amp bridge to feed the fuel delivery system. Intermittent stalling or "crank-no-start" scenarios frequently trace back to pitted contacts on this specific internal relay.
Unlike a simple toggle switch, the BSM B3 utilizes a . Always ensure you are working with the official,
A schematic layout reveals several critical fuse pathways running through the B3 unit: : Engine Control Unit (ECU) power supply. F2 (15A) : Horn. F4 (10A) : Right high beam. F5 (10A) : Left high beam.
