In addition to the column shifter, another component associated with the shift selector is the Neutral Start Back Up (NSBU)switch mounted on the selector shaft of the transmission. The NSBU switch transmits selector position information to the TCM. The NSBU switch mounts inside the transmission housing and detects the angular position of the shift selector shaft. This position is communicated to the TCM so that certain vehicle control functions can be coordinated with the position of the shift controls. The neutral signal output of the NSBU switch is typically used as confirmation that the transmission is in NEUTRAL or PARK before the engine starter is engaged.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon trouble codes associated with NSBU failure include:\u003cbr\u003e\u003c\/strong\u003eDTC P0708, Neutral start\/backup (PNP or NSBU) switch\u003cbr\u003eDTC P0847, Pressure Switch Manifold (PSM)\u003cbr\u003eDTC P0872, Pressure Switch Manifold (PSM)\u003cbr\u003eDTC P0875, Pressure Switch Manifold (PSM)\u003cbr\u003eDTC P1711, Pressure Switch Manifold (PSM)\u003cbr\u003eDTC P1713, Pressure Switch Manifold (PSM)\u003cbr\u003eDTC U1000, Serial Data Communications\u003cbr\u003eBlank PRNDL Display\u003cbr\u003eFlashing PRNDL Display\u003cbr\u003eSlow or No Engagement of Automatic Transmission\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits: 2006-2016 6.6l Duramax LBZ LMM LML with 6 Speed Allison Transmission\u003c\/strong\u003e\u003c\/p\u003e","brand":"KB Diesel Performance LLC","offers":[{"title":"Default Title","offer_id":51093319909680,"sku":"KB-29542692-NSBU","price":175.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0938\/7524\/1264\/files\/2577093945.jpg?v=1773192468","url":"https:\/\/mountain-viewdiesel.myshopify.com\/products\/neutral-safety-switch-nsbu-for-6-speed-allison-6-6l-duramax-06-16-29542692","provider":"Mountain View Diesel","version":"1.0","type":"link"}
