If a BHM needs replacement, it must be replaced with the new BHM (A66-03086-000) with a 500k auto baud rate. IMPORTANT: It is normally not necessary to replace the BHM. Replacing the BHM should be a last resort to solving electrical problems, unless the unit needs replacing due to physical damage.","document":null,"url":"https://open.wenmarpro.com/bulletins/10076457","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FREIGHTLINER","model":"FREIGHTLINER","year_from":null,"year_to":null,"match":"exact","vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
