OBD II Mode 6 Diagnostices
 

Is anyone here familiar with mode $6 diagnostics and how to access the information. I have a 1996 C280. I've used a Centec Scanner that's supposed to read this module but will only say it is not supported when hooked up to my car via the OBD II plug. I'm trying to see if it will provide any information on why the EGR and 2ndary Air OBD II Monitors will not run. Thanks.
