Greeetings, this is maybe the 3rd time my oil service light has gone on. Using the re-set procedure of grounding pin 7 on the diagnostic port worked the first 2 times, but not this time. using the re-set procedure does nothing, the light stays on..did this maybe 3 times, same result. I need to check the wire I guess just to make sure, but it looks ok. Any body face this one?

Well, I guess a 5 inch piece of plain wire can go bad...tried the same re-set procedure with a new wire, and what do you know..it worked...and they ask me why i drink:rolleyes:

I was going to guess SI batteries, but you beat me to the punch.

Do you ground the wire to the diag port pin (19?) or to the chassis?

If you have to keep resetting the light, the board is having issues. You can try to swap out the batteries first, but if that does not work, the board needs to be swap out.

when it didnt work the first time I tried pin 19 instead of the usual chassis ground-I know either one will work, but neither would until I got a new wire. The one that seems to have gone bad was a "fancy" one, with a pin soldered to one end, a fuse and then an alligator clip soldered on the end. I cant believe this rig failed(the fuse didnt blow) I used an old piece of a radio loom to replace it, it has an inline fuse but just plain wire ends. I just stuck one wire in the #7 hole and hold the other end onto a strut bolt and that worked. just when you try to do something nice....

Fancy stuff never works right. It needs to be all dirty or sumthin'.

yeah, a paperclip would do it also. basically all you need to do is ground pin #7, but it seems safer to me to ground the pin to chassis ground, cause bad stuff may happen if you touch something other than ground while hooked up to the pin
