The hydraulic still stays in tact
Since the hydraulic system seems intact, check the ABS fuse and relay for any faults. A faulty fuse or relay can cause the ABS light to come on. If these components are fine, it might be necessary to have a professional diagnose the ABS actuator. Let me know if you need further assistance!

Check the wheel speed sensors for any dirt or damage, as they can also trigger the ABS light. Clean them if necessary and ensure the connections are secure. If the issue persists, consider having a professional inspect the ABS system. Let me know how it goes!

ABS, VSC, Brake lights up . The scan code shows C1391 abnormal leakage . I also observed the Hydraulic fluid had become darker recently. I just need some Guidance before I visit the experts around here

Is there any Carly live data that can assist narrow it down to the exact components?

Check the live data for the brake fluid pressure and wheel speed sensor readings. Compare the pressure readings to the specifications in your vehicle's manual to identify any discrepancies. If the pressure is inconsistent or the wheel speed sensors show irregular data, it could help pinpoint the issue. If you find any anomalies, it’s best to consult a professional. Let me know if you need more help!

Inspect the brake fluid for contamination, as darker fluid can indicate moisture or debris, which might affect the system's performance. If the fluid is contaminated, consider flushing and replacing it. If the problem persists, seek professional assistance. Let me know if you have further questions!

The C1391 code indicates an issue with the ABS accumulator or a leak in the brake actuator assembly. Start by checking the brake fluid level and ensure there are no leaks in the system. If the fluid level is fine, it might be a more complex issue with the actuator, which would require professional inspection. Let me know how it goes or if you have more questions!
