if it has the 95640 chip then clear
00001000 to 00001610 (incluing both lines ) to f's
this will remove all the crash data then rewrite the chip with the editted bin file if you have the equipment .
if not plenty of tuts online to make a chip reader with it on board , or if you can remove the chip a programmer is only about £3 and and the lead to connect to chip is about £1
so all can be had for less than £5 , some sell complete kits for around £5 .
