1987 Mitsubishi Starion ESI-RFACTORY OEM SERVICE PROCEDURE

Control Unit

The control unit is located inside the luggage compartment. It receives signals from the pulse generator, "G" sensor, and the stoplight switch. Once the signal has been received, it sends the brake fluid pressure control signal to the modulator. It also will detect a malfunction in the control unit or modulator or an open circuit, and return the brake system to conventional operation.
