Suzuki Brake Warning Lamp Wiring Diagram - Fluid Level, Parking Brake, RWAL

This is one page of a factory-style wiring diagram covering the brake warning lamp circuit in the combination meter. It shows the BRAKE warning indicator fed through the combination meter (pins 9/14 and 11/10 on connectors [3] and [4]), with a diode branch noted for vehicles equipped with auto-cruise control. The warning lamp circuit is grounded through several switches wired in parallel: the brake fluid level switch (connector E21), the brake differential switch on the proportioning and differential valve (connector E30), and the parking brake switch (connector L27). A branch also runs to the RWAL (rear-wheel anti-lock) control module. The right side of the diagram shows the ignition switch (connector E42) with positions ST, IG2, IG1, ACC, and LOCK, grounding through points 10 and 9. Wire colors are labeled throughout: R/B (red/black), V/R (violet/red), B/G (black/green), V/G (violet/green), and B (black). Grounding variations are shown for 2-door 8V versus 2-door 16V and 4-door body styles. Connector identifiers visible include G05, E38, E21, E30, E31, L27, L28, L32, L34, and E42. A reader can trace how the brake warning lamp is triggered by low brake fluid, parking brake application, or brake pressure differential.
