- Malfunctioning brake pedal angle sensor
- Damaged or corroded wiring connections
- Faulty electronic control unit (ECU)
- Water or debris intrusion into the sensor
- Electrical issues such as short circuits or power supply problems
Symptoms of C100A Mercury
- Illumination of the brake warning light on the dashboard
- Inconsistent or delayed response when applying the brakes
- Loss of traction control or stability control functionality
- Adaptive cruise control not functioning properly
