Abstract: A remote fault indicating unit (12) for an electronic system, such as a vehicle adaptive braking system, includes a series of visual indicators, such as light emitting diodes (50-59), on one surface of the housing and a computer serial port connector (13) for use when troubleshooting is done with a PC (18) equipped with the appropriate software. Each of the indicators (50-59) is activated in response to a predetermined malfunction sensed in the system, such as a defective speed sensor, defective modulator, or a defect in the electronic circuitry. The indicators (50-59) are reset with a switch (15) when the system is repaired. When the reset switch (15) is activated, all of the indicators (50-59) flash on and are then turned off. The reset switch (15) can also be activated for a longer period of time changing the ECU (14) configuration.
