Brake Monitoring Function
The Brake ECM monitors the status of switches and sensors that are related with the brake system. The following specific parameters are monitored by the Brake ECM:Brake Accumulator Pressure
The Brake ECM determines the status of the accumulator pressure for the service brake by monitoring the "Service Brake Accumulator Pressure" Sensor. This switch changes states when the pressure is low and the ECM outputs this low pressure status to the monitoring system for display.Second Brake Accumulator Pressure
The Brake ECM determines the status of the accumulator pressure for the secondary brake by monitoring the "Secondary Brake Accumulator Pressure" Sensor. This switch changes states when the pressure is low and the ECM outputs this low pressure status to the monitoring system for display.Service Brake Pressure
The Brake ECM determines the status of the service brake pressure by monitoring the "Service Brake Pressure" Switch. This pressure switch changes states when the service brake is active and the brake lights are driven accordingly. "Brake Filter Bypass" Pressure
The Brake ECM detects the clogging of the filter for the brake fluid by using the "Brake Pump Pressure" Sensor. When a pressure reading that is out of the expected range is detected the Brake ECM will respond by activating the "Brake Filter" Switch. This switch changes states when the filter is clogged and the ECM outputs the filter condition to the monitoring system for display.Brake Oil Temperature
The Brake ECM determines the brake oil temperature, by using temperature sensors that are located at the left and right front and left and right rear of the truck. The Brake ECM outputs this temperature status to the monitoring system for display. The Brake ECM will also act accordingly if the temperature falls outside a predetermined range.
