I have an auto accord..when I turn the car on, the D4 gear in the cluster starts to blink and stays blinking when yhe car is in use,, what does this mean? How do I turn this off?

 

There is a stored trouble code, you will need to retrieve the code and fix the problem.

What year is your Accord?

 

1992

 

Passenger side kick panel.
Look above it, there should be a two wire blue connector either attached to the wire harness or floating in space.
Use a wire(metal paperclip)to jump the connector.
Turn ignition to II(ON)
Watch the D4 light blinks, record the code produced, long blinks are multiples of 10, shorter ones are multiples of 1.
Report back here with code(s) for further diagnostic aid.
