What's the differance?

[KC96LSC]

What is the difference between the check engine lights? One is below the info center, what are the issues it points out? and the other in the info center, what does it respond to.

Thanks,

Just curious.

93-95 only have 1 and they are non-OBD. 96-98 are OBD is that why they have 2?
