Thank you for your response. Do you experience problem when it runs or its just blinking? When this blinks normally it has deal with the transmission fluid, it might be low or you need to flush it and replace it with a new one. Make sure you used the HONDA transmission fluid whe you change it. Hope this helps.

Replace the transmission fluid. And make sure to use a HONDA transmission fluid.

Hi James. Can you try to remove the negative battery connector for about 5 minutes and then connect it back again and see what will be the result.

If the blinking D1 light still there after you disconnect and connect the battery back, then advise your mechanic to check the Pressure switch on your transmission. Please check the picture below for your reference.

If you have questions feel free to post your responses here.

This is located on the transmission. Show the picture I just provided you to  the mechanic so they will know what switch we are referring to and then advise them the D1 is the one blinking so they will know which pressure switch to replace. This switch cost around $50.

As it turns out, I am scheduled to go offline now. I would really appreciate the opportunity to personally make sure you are satisfied with your answer and if it's OK with you, I'd like to continue our conversion 10 AM CST.
