What is CID 15:
CID 15 refers to a problem with the vehicle’s braking system, specifically related to brake fluid pressure. The ECM detects a fault with the pressure sensor circuit, which can lead to improper brake function and affect vehicle safety.
Why This Happens:
- Faulty brake fluid pressure sensor.
- Shorted or damaged wiring in the brake control circuit.
- Low brake fluid levels.
- Malfunctioning brake booster or valve.
- ECM misinterpreting the pressure sensor’s data.
How to Fix It:
- Inspect the brake fluid pressure sensor and its wiring for damage.
- Test the sensor’s voltage and resistance to ensure it is functioning correctly.
- Ensure brake fluid is at the proper levels and check for leaks.
- 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 brake system diagnostics.
- Replace brake fluid and components on schedule.
- Clue’s safety management services help monitor braking systems and prevent issues before they affect vehicle performance.
