Input Signals

Input signals





The control module receives input signals on the car's operating conditions from the following components:
- Wheel rotation speed, acceleration and retardation from wheel sensor and pulse wheel. (1, 2)
- Signal from EBD pressure sensor when the primary circuit is pressurized. (3)
- Signal from brake light switch when the driver depresses the brake pedal. (5)

And in cars with TRACS:
- When TRACS cuts in or out from the switch on the instrument panel (dashboard). (9)

The following are needed for the control module to function:
- Voltage supply, 30-supply, from the battery. (6)
- Voltage supply, 15I-supply, from the ignition switch. (7)
- Ground connections.
