STOPLIGHT SWITCH SPECIFICATION
| NAME OF PART | NUMBER | OUTLINE OF FUNCTION | |
|---|---|---|---|
| Sensor | Wheel speed sensor | 1 | Outputs the frequency signal in proportion to the rotation speed of each wheel to ASC-ECU. |
| Magnetic encoder for wheel speed detection | 2 | The wheel speed sensor is a pulse generator. When the magnetic encoder for wheel speed detection (a plate on which north and south pole sides of the magnets are arranged alternately) rotates, it outputs frequency pulse signal in proportion to each wheel speed. | |
| Stoplight switch | 3 | Outputs the signal indicating whether the brake pedal is depressed or not through ETACS to ASC-ECU via CAN-bus line. | |
| G & yaw rate sensor | 4 | Detects yaw rate longitudinal (AWD only) and lateral acceleration of a vehicle, and outputs signal to ASC-ECU via the CAN line. | |
| Steering wheel sensor | 5 | Detects the steering angle of the steering wheel, and outputs signal to ASC-ECU via the CAN bus line. | |
| ASC OFF switch | 6 | Outputs the ON/OFF signal through ETACS to ASC-ECU via CAN-bus line to turn on and off skid control function and traction control function. | |
| Pressure sensor | 7 | Integrated into the hydraulic unit, and outputs the signal for the brake fluid pressure in the master cylinder to ASC-ECU. | |
| Brake fluid level switch | 8 | Outputs a drop in the brake fluid level in the brake fluid reservoir tank through ETACS to ASC-ECU via CAN-bus line. | |
| ACTUATOR | Hydraulic unit | 9 | Drives the solenoid valve using the signal from ASC-ECU, and controls the brake fluid pressure for each wheel. |
| ABS warning light | 10 | Informs the driver of the system status by illuminating, flashing, or turning off the warning light according to the signal from ASC-ECU. | |
| Brake warning light | 11 | Used as the warning light for the parking brake, brake fluid level, and EBD control. Informs the driver of the system status by illuminating, flashing, or turning off the warning light according to the signal from ASC-ECU. | |
| ASC operation indicator light | 12 | Traction control function and skid control function use the same display. Depending on the signal from ASC-ECU, the indicator light informs the driver of the system status by flashing when the system operates and by illuminating when skid control function or traction control function has a malfunction. | |
| ASC OFF indicator light | 13 | Informs the driver of skid control function and traction control function shutdown by the signal from ASC-ECU. Informs the driver that the brake system overheats and the brake traction control stops by flashing the indicator light in approximately 2 Hz. | |
| Data link connector | 14 | Sets the diagnostic trouble code and establishes the communication with scan tool. | |
| Engine ECU | 15 | Controls the engine output based on the signal from ASC-ECU. | |
| AWD-ECU | 16 | Outputs the drive status to ASC-ECU. | |
| ASC-ECU | 17 | Controls actuators (described above) based on the signals coming from each sensor. | |
| Controls the self-diagnosis and fail-safe functions. | |||
| Controls the diagnostic function (scan tool compatible). | |||

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
