What it means
The EBCM or cluster detects a fault related to the brake-fluid level signal (low level detected or level-switch circuit fault). Low fluid commonly tracks to pad wear or leaks; electrical faults include an open/short in the level-switch circuit. CarParts+1
Symptoms
- Red brake warning; “Low Brake Fluid” message on some platforms; ABS/ESC may set related messages. Colorado Fans
Common causes
- Actual low brake fluid (wear/leak).
- Faulty reservoir level sensor/switch; wiring/connector issues. CarParts
Diagnostic notes / fixes
- Physically confirm fluid level/leaks before chasing electrical faults.
- If level is correct, test the level-switch circuit for open/short; repair wiring or replace the sensor as needed. Real Autohaus
