- Damaged wiring or connectors leading to the brake master cylinder pressure sensor
- A faulty brake master cylinder pressure sensor
- Issues with the electronic control unit (ECU)
- Corrosion or moisture affecting the sensor circuit
- Electrical issues within the braking system
Symptoms of C1953 Mazda
- Illumination of the ABS warning light on the dashboard
