I know most people on here are buying the Diablo Predator for a performance tune. However, in convincing my wife on why I should get one, I used the arguement that it is an OBD-II scanner. I need one for my 97 T-Bird.

I argued, heck, it is two products in one. She said ok. I got it in today and tried to read a code/CEL on my 97- T-Bird. It said "no vehicle information available."

I called Tech support to figure out why, since 97 is an OBD-II compliant.

Tech support said the 05 Predator has a different program. It can read certain cars from previous years, but it is very limited. I think he said an 04 mustang or 150.

Tech support said they will check into whether they will offer an update to the unit to allow it to read older OBD-II codes. But he said any update is at least a month away. I am fine if it is a month away, as long as it becomes available.

Now I have to figure out a new reason that my wife will accept to keep the unit .

 

What's that saying, possesion is 9/10th's of the law

 

Most likely it's only because the scanner will only read CAN (the ODB-II protocol) used by the new mustang and the F150.

Most of the older cars used one of the following

AT1: SAE J1850 VPW (Variable Pulse Width Modulation)
AT2: SAE J1850 PWM (Pulse Width Modulation)
AT3: ISO 9141-2, ISO 14230-4 (Keyword Protocol 2000)
