Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

MY DIAGNOSTICS PLUG UNDERDASH IS AN OBD1 TYPE! BUT IT HAS NO WIRE IN PORT (B) TO SHORT TO WIRE (A) SO AS TO READ OUT ERROR CODES WITH THE CHECK ENGINE LIGHT FLASHING. I HAVE EXPERIENCE WITH OBD1 AND HAVE NO TROUBLE USING A PAPERCLIP READING ERROR CODES. I HAVE BEEN TO THE JUNK YARDS AND INVESTIGATED THE DIAGNOSTIC PLUGS. ALL SIMILAR VANS 1995 LUMINA-SILOUOTE-AND TRANSPORT HAVE THE SQUARE OBD1 PLUG BUT THEY DO NOT HAVE A WIRE IN PIN (B)! I HAD NO TROUBLE WITH CHECKING MY 1989 CHEVY TRUCK 0R 1993 CAVALIER. I HAVE AN OBDII READER BUT THE PLUG WILL NOT MATCH. I HAVE FOUND OUT THAT 1995 WAS A TRANSITION YEAR FOR DIAGNOSTICS,SO I HOPE THAT SOMEONE HAS A SOLUTION TO READING MY DIAGNOSTICS-MAYBE AN ADAPTER PLUG?
