ON CERTAIN MACK MODELS, BUILT BETWEEN 09/04/2010 AND 08/15/2014, WITH AN AIR SLIDE 5TH WHEEL, THERE WILL BE NO WARNING WHEN THE OUTPUT FROM THE VECU GETS SHORTED TO GND. THIS CAN CAUSE THE 5TH WHEEL TO SLIDE WITHOUT ACTIVATING THE 5TH WHEEL SLIDE SWITCH. THIS IS DUE TO THE FACT THAT THE SW IN THE VECU AND INSTRUMENT CLUSTER DID NOT SUPPORT THE FAULT MONITORING FOR THIS FUNCTION. PERFORMING THE BELOW PROCEDURE WILL ACTIVATE THE FAULT MONITORING AND WARNING.","document":null,"url":"https://open.wenmarpro.com/bulletins/10083525","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"instrument-cluster","name":"Instrument cluster","parent":"electrical"},{"id":"software","name":"Software","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"MACK","model":"CHU","year_from":2011,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"MACK","model":"CXU","year_from":2011,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"MACK","model":"GU","year_from":2011,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"MACK","model":"TD","year_from":2011,"year_to":2015,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
