yet another "D4" question

[bravedude]

hello, can anybody tell me what could be the cause why my d4 light is completely off? all other lights work fine. just that one is out. and the car has been stalling out. up until it shut off it runs fine. any help would be great. thanks

[emosun]

Does it shift through all four gears and overdrive correctly?

[bravedude]

yes it shifts fine. i get code 15 ? 1 long flash and 5 short ones. damn car made my fat butt walk home today

[illinois_erik]

sometimes i get that..itll crank and crank and crank..so I pull the ecu fuse for about 10 mins no less..reinstall and itll fire right up as if nothing was wrong. The only way Ive reproduced this problem is by putting it into neutral shutting off the car and rolling to a stop..like if i was creeping up on someones house or what have you. It doesnt do it often, but every time its spontaneously done it resetting the ecu has always worked

[bravedude]

cool, i could find the link for the codes, thank you !

[bravedude]

sorry, could'nt is what i meant.

[SilverShadow]

cool, I couldn't find the link for the codes, thank you !

(I fixed your quote) You are NOT serious? The codes are all over this forum and on others too! I even copied both ECU and TCU codes from here and used them on a site I had. Whats more...the manual has them. But because I'm not all mean old guy....
