I bought a 1993 accord that was running great then one day got it home started it up to move into garage. I notice the d4 light stayed on went I shift into other gears. No power in d 4.. The light is solid and i tried the jumper but cannot get code. when I disconnect and re connected the battery it ran good for about a mile then it acted up again. I changed out the TCU with a knowned good one but problem was still there. I was wondering if the main relay would have a part with this.
