Brake Fluid Level Sensor/Switch: Testing and Inspection

1. Disconnect the level switch connector C126.
2. Connect an ohmmeter between the switch terminal.
3. When fluid level is above MIN level, the ohmmeter should indicate no continuity.
4. Unscrew cap from brake fluid reservoir and allow float to fall.
5. When float is at its lowest point, the ohmmeter should indicate continuity.
6. If continuity is not as specified, replace switch.
