Perhaps I've mis-spoken. I get some codes marked in yellow color. My understanding these are not active codes, but rather some code history -- things that happened in the past. When I tried clearing all codes with PA Soft, it had cleared the yellow DME codes, but not the codes for ABS and Wheel speed sensors. I believe these codes resulted from the dyno used for the smog test, but still curious why they are not clearing from some modules while clearing from the others. Thanks
