Brakes grind, pulse or wear early

The Vehicle Stability Assist (VSA) system in the model year (MY) 2005 Honda Pilot vehicles integrates braking control strategies for anti-lock braking, traction control, electronic stability control and brake assist functions. The system consists of a VSA modulator (an electronic control unit and electronic/hydraulic actuator) that receives data from an integral brake pressure sensor and from wheel speed sensors (four wheels), the steering wheel angle sensor and a combination yaw rate and lateral acceleration sensor.Allegations of unexpected braking appear to be related to inappropriate activation of the brake assist (BA) function.The BA system is designed to minimize stopping distances in emergency braking maneuvers by rapidly applying maximum braking force when a panic stop is detected. ODI's analysis of complaints and information provided by Honda in its response to DP12-002 and PE12-028 identified fault conditions that may result in false detection of a panic stop by the BA system, resulting in unexpected, severe brake application. The VSA control algorithm should detect inappropriate BA activation in less than 1 second and turn the system off. However, some complaints allege longer duration incidents of severe braking with no brake pedal application. Honda implemented countermeasures in the control and fault detection algorithm in the MY 2006 Pilot VSA modulators, which are not interchangeable with the MY 2005 parts.Allegations of steering anomalies appear to be related
