Once this crash flag is written, the 48V system locks out and cannot be re-armed by standard diagnostic tools, since the crash record is held in a protected memory area. This typically triggers fault codes such as P1069, disables mild-hybrid start-stop assistance, and can prevent a clean MOT pass.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.4rem;font-weight:700;margin-top:36px;margin-bottom:10px\"\u003eCan the 48V Battery Be Reset Without Replacement?\u003c\/h2\u003e\n\u003cp style=\"line-height:1.7;margin-bottom:20px\"\u003eYes — in the large majority of cases, the 48V battery itself is undamaged; only the BMS crash flag needs to be professionally cleared. Replacing the entire 48V battery at a dealership can cost significantly more than a reset service, and is often unnecessary once the crash data has been properly addressed.\u003c\/p\u003e\n\n\u003ch2
