In addition, DTCs B1325, B2750, B305D, B297B, C0049, P0562, P0700, U0100, U0101, U0102, or U3006 may be set. Some conditions may be noticed more with powertrain movement, such as when accelerating or braking.<\/span><\/p>\n<p class=\"western\"><span style=\"font-size: 12pt;\">These electrical concerns may be caused by the X50A Underhood Fuse Block bolts (Fig. 20, #1) being loose. The fuse block has built-in indicators (Fig. 20, #2) next to the bolts that pop-up as the bolts are tightened to indicate that the fuse block is fully installed. In some cases, the green indicators will be popped up but the bolts may still be loose. <\/span><\/p>\n<p class=\"western\" style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-13425\" src=\"https:\/\/techlink.mynetworkcontent.com\/wp-content\/uploads\/2020\/07\/F20-ubec-1.png\" alt=\"\" width=\"740\" height=\"480\" srcset=\"https:\/\/gm-techlink.com\/wp-content\/uploads\/2020\/07\/F20-ubec-1.png 740w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2020\/07\/F20-ubec-1-300x195.png 300w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2020\/07\/F20-ubec-1-85x55.png 85w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2020\/07\/F20-ubec-1-200x130.png 200w\" sizes=\"auto, (max-width: 740px) 100vw, 740px\" \/><span style=\"font-size: 12pt;\"><b>Fig. 20<\/b><\/span><\/p>\n<p class=\"western\"><span style=\"font-size: 12pt;\">Check the fuse block bolts for properly installation.
