Circuit Description

Pressure Modulator Valve (PMV) fluid level switch alerts EBCM/EBTCM of low brake fluid condition in PMV reservoir. Switch is located in PMV fluid reservoir and is normally closed when reservoir contains sufficient fluid. When fluid level is low, switch opens, causing EBCM/EBTCM to turn on ANTI-LOCK warning indicator.
