Blinking D4 Light on EK4 SiR

[travis_sts]

Hey guys, need some info/advice.
The D4 light began flashing non stop this morning, however, had no problems while driving, car worked normal, no hessitation or nothing. It's a 2000 EK4 SiR Civic.
Any advice/suggestions as to what would cause this would be appreciated.

it indicates a possible problem in the transmission.avoid rapid acceleration and have transmission checked.....

I think it could also mean that the speed sensor faulty

I actually had the flashing D4 light when my speed sensor went bad... Sometimes the sensor would work, other times it would throw a CEL, but all the time while it was bad the D4 light was blinking...

It could be your alarm, or one of your door sensors. Try putting your hood light on and see if its comes on and off.

just reset... take the negitive off for a while...
it could be low fluid..an that speed sensor thing...

how long you have the vehicle?.

does your speedometer and tach work? if so, speed sensor is good. change your filters and oil in the tranny. if not, the tps sensor should be checked. this works with the tranny also. what cel codes are you getting?
