Truck Shipments Deferred Due to Potential Bendix ATR-6 Valve Defect

Bendix has identified a potential defect in its ATR-6 valve manufactured between December 2, 2010, and January 18, 2012, and has advised the National Highway Traffic Safety Administration (NHTSA).

The defect, which can potentially occur only in vehicles operating in extremely cold conditions (at or below 0 degrees Fahrenheit or -18 degrees Celsius), has caused several vehicle manufacturers – PACCAR, Volvo, and Navistar – to defer shipments of trucks with the ATR-6 valve manufactured between December 2, 2010, and January 18, 2012.

Approximately 50–60,000 vehicles are covered.

Bendix said a temporary remedy kit is available now. A permanent remedy kit will be forthcoming.

The ATR-6 valve is an Automatic Traction Control Relay Valve. Vehicle operators are advised that this is an intermittent air leakage issue, not related to Bendix stability systems. Vehicle ABS and service braking will still operate normally on covered vehicles.

If a vehicle operator elects to install the temporary remedy kit, Bendix ESP full stability system and Bendix Wingman ACB & Wingman Advanced will be temporarily suspended until the permanent remedy kit is installed.

A Q&A about this issue is available through the Bendix ATR Value Update link at In addition, a Bendix ATR-6 Action Line is staffed from 7 a.m.–8 p.m. ET seven days a week for technical questions and ordering information. The toll free number is 1-800-478-1793.
