thanks for your quick reply.

My D4 flashes four times, then pauses then repeats. I didn't see any breakdown of D4 codes in your charts above. I only saw a footnote at your explanation of 70 in your initial post that said " ** The D4 indicator light and Malfunction Indicator Light (MIL) may come on simultaneously."

By the way, I edited my previous post for clarification and to include more info.
