CHEVY OBD II OR NOT?

2008 Chevrolet Silverado

Computer problem
2008 Chevy Silverado V8 Four Wheel Drive Automatic 6000 miles

I have an Actron CP9135 OBD II AutoScanner and I can not get it to communicate with my new Silverado 2500HD, all I get is " Link Error.&Quot; I checked the Vehicle Emissions Control Information decal in the engine compartment and it says the vehicle is " OBD II Certified.&Quot; Shouldn't these two " OBD II" compatible devices communicate properly?

I tried the scanner on our 2006 Toyota Tacoma and got the " Link Error" also. The scanner works with my friends 2004 Dodge Ram and my old 1999 GMC Sierra.

Confused.

The newer vehicles use a different communications bus. It is still OBDII, but you must use a CAN compliant scan tool to communicate with the vehicle.
