Right Front Brake Hydraulic Circuit Leaking
Right Front Brake Hydraulic Circuit Leaking
Description
Ignition ON, accumulator pressure is less than 9,000 kPa (1,305 psi). The ignition voltage is greater than 10 volts. The EBCM performs a hydraulic system check every third ignition cycle. Brake pedal was depressed.
Cause and Solution
This diagnostic detects if the left front circuit is leaking by actively applying pressure and monitoring the accumulator pressure change. The pressure change of the accumulator indicates the volume of fluid used which is then compared to expected fluid used during a brake apply. Too much fluid usage indicated a leaking circuit.
