Service bulletin 23PBC

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Safety Recall Bendix has established a repair procedure and is providing the parts to update and correct this issue. Certain tractors equipped with Bendix Intellipark Tractor Park Valve Module (PVM) may intermittently become stuck in the un-parked position and may not transition from un-parked to parked when the park switch is pulled on the vehicle dashboard. Warning which can precede or occur: 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 typically are heard as an air-braked vehicle is parked will not be heard indicating that the vehicle is not parked.
