My OBD will not power up on a 2005 pontiac montana.


SP205 is a splice pack , taped to the wiring harness behide the dash near the OBD connector .

My OBD will not power up ? Code reader , scan tool ????? .Pin #16 at the OBD connector should have B+ voltage .This is what supply's B+ voltage to the scan tool / code reader . What makes you think you need a computer ? The computer doesn't supply B+ voltage to that OBD port ,.Do you know where the i/p fuse box is ? You want the CIGAR/DLC /APO FRT fuse 20amp . The other wires you mention above , don't mess with those . Those are the class 2 data bus wires .Screw with those and short one out , you will never get your vehicle started . Suggets you google GM class 2 serial data bus communications .
