Nissan Micra Warning Chime Wiring Diagram - Warning System (EL-51, SEL519I)

This document is a single page (EL-51) from a Nissan factory service manual, showing the Warning System — Warning Chime/Wiring Diagram (figure SEL519I). The schematic shows power flow from the battery and the ignition switch (ON or START positions) through two 15A fuses in the fuse block. From the fuses, a G/OR (green/orange) wire and a Y (yellow) wire feed the circuit. Components shown include the seat belt timer (connector 57M, wires Y, B, LG/R, with the LG/R branch going to the seat belt warning lamp), the warning chime unit (connector 58M, wires G/B, B, LG), the key switch (connector 70M, wires G/B and G/R), the seat belt switch (connector 66M, wires LG and LG/R), the driver's door switch (connector 77M, wires G/OR and G/R, grounded at the switch), and body ground points at connectors 13M and 55M via a B (black) wire. A reader can use this page to trace the warning chime circuit, identify wire colors and connector numbers, and diagnose problems with the key-in-ignition, seat belt, and door-ajar chime functions.
