4th GEN Owners.... how do you clear a check engine code?
 

Ok, so it's not a check engine code... My neighbor has a 4th gen w/ 7500 miles on it and BAM the maintainence light popped on. Duh. He just wants to clear it until he gets to the dealer. On most any other car, you can pull the EFI fuse or the ECU fuse or at very least the pos and/or neg. terminal on the battery and the computer will lose the code. That didn't work on this vehicle. Suggestions?

Thanks in advance!

I'm hazy on this, but think the procedure is covered in the owner's manual.

Seriously? I never thought to look there... Why the heck would Toyota tell you how to clear a code in the OWNER'S MANUAL? Seems like that would be detrimental to there funds received from people coming in b/c they're freaked out about a little light. I'll look into that... any other suggestions?

To accommodate the DIY crowd. It comes on when an oil change is due...maybe other things, too, but I recall some kind of explanation in the manual.

Try this...

SWEET. Thanks!

Mine just came on yesterday. Actually, it just stayed on for about 5-7 seconds longer than it normally does during start up, then it went off. I've read of other people having this happen, and I too have had it happen once before, but right after an oil change. I last had my oil changed in mid January. I went ahead and reset the light under the assumption if something was wrong that it would come back on. Am I right?

Mine popped on a few days ago, but nothing seems wrong with the truck. It's about due for an oil change, so I'll mention it when I do that.
Perhaps it's set for oil change times. Beats me, never hurts to have it looked after if it's under warranty.

If you have your oil changed at the dealer, don't expect the porter to reset the counter. I found my dealer doesn't reset the counter after my oil change. Kinda defeats the purpose doesn't it?

Yeah, David nailed it. Just follow those instructions...I had to do it a few thousand miles ago.

This specific indicator is triggered by mileage only. It is set, on my '03 to come on after 7,500 miles. It is not in response to any mechanical sensor or faliure.

At about 5,000 miles, it stays on for a few extra seconds as kronicx had, then at about 7,500 miles it stays on constantly.
