FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : AS reported in Bendix’s recall 23E-015; An Intellipark PVM that intermittently becomes stuck in the un-parked position does not allow the vehicle spring brakes to exhaust when the driver pulls the Park Switch. The vehicle must be parked by depleting air storage by fanning-down the air brake system with the service brake pedal. If a driver does detect the Intellipark PVM malfunction indications and does not properly fan down the brakes, the vehicle may unintentionally move which increases the likelihood of a crash. Description of the Cause : • As reported in Bendix recall 23E-015; Mechanical components in the PVM that are at the upper limit of the design specification and other tolerance stack-ups allow for excessive internal air leakage. The internal leakage does not allow pressure to build properly when the pilot solenoid is activated. Identification of Any Warning that can Occur : As reported in Bendix recall 23E-015; Park Indication LEDs on the park switch remain off after the Park Switch is pulled indicating that the spring brake system has not exhausted and the vehicle is not parked. Audible exhaust sounds that are typically heard as an air-braked vehicle is parked, will not be heard indicating that the vehicle has not parked. The vehicle manufactures have implemented dash display indications and alerts indicating that the vehicle has not parked in response to pulling the Park Switch.
