Check Brake Fluid Level Message

The IPC supplies 5 volts to the low brake fluid circuit. The IPC supplies and internally monitors the voltage level of the circuit at connector C2, terminal "A11." If the fluid level drops low enough the switch will ground and the IPC will detect a ground (less than 1-volt) at terminal "A11." If the voltage remains at ground for at least one second, the IPC will display the "CHECK BRAKE FLUID LEVEL" message. The IPC will Also broadcast this message over the Class 2 serial data bus to the PZM for use by the ABS/TCS controller.
