What is CID 246:
CID 246 refers to a problem with the vehicle’s braking system, specifically related to the brake fluid pressure sensor. The ECM detects an issue with the sensor, which could lead to improper brake function and safety risks.
Why This Happens:
- Faulty brake fluid pressure sensor.
- Shorted or damaged wiring in the sensor circuit.
- Low brake fluid levels.
- Malfunctioning brake booster.
- ECM failure to process the sensor’s data.
How to Fix It:
- Inspect the brake fluid pressure sensor and wiring for damage.
- Test the sensor’s voltage and resistance to ensure proper functionality.
- Check for leaks and ensure brake fluid is at the correct level.
- Replace the faulty sensor or malfunctioning brake components.
- Perform a diagnostic check to ensure the brake system is operating correctly.
How to Avoid It Before It Happens:
- Regularly inspect the brake system and fluid levels.
- Keep connectors clean and free from corrosion.
- Perform routine diagnostics on the braking system.
- Replace brake fluid and components as needed.
- Clue’s safety management services track braking systems and prevent issues before they affect vehicle performance.
