Hi I have a 1995 Z28 the ABS light is on all the time I plugged in my OBD2 code reader into plug under dash on the drivers side the plug fits in perfect but it won't work and it is a 16 pin plug my OBD1 code reader won't fit. and under the hood the label says car is OBD1 certified do they make a OBD1 code reader with the same 16 pin plug as the OBD2 as I want to scan the ABS system and is it possible on whatever system? OBD1 or OBD2 to change the shift points in the transmission it's a LT1 Motor and a 460 LE trans and what code reader do i need that takes the OBD2 plug but runs a OBD1 system or is there a separate code reader or scanner that does the ABS alone http://www.hotrodders.com/forum/images/smilies/confused.gif http://www.hotrodders.com/forum/images/smilies/confused.gif http://www.hotrodders.com/forum/images/smilies/confused.gif http://www.hotrodders.com/forum/images/smilies/confused.gif http://www.hotrodders.com/forum/images/smilies/confused.gif http://www.hotrodders.com/forum/images/smilies/confused.gif
