Hello my friends,After changing the oil for your car, the oil service light stays on (on the red) and it becomes very annoying to you sometimes. It makes me upset just to see it like that, so I wanted to find out how this creature is reset. It turned out that the procedure is very simple and it doesn’t need time, money or even special equipment. Well, only a paperclip ;-). The following article will show you how this thing is done within couple minutes. BTW, I didn’t write this article. I found it here in case you want to read it. Ready? ok here we go . . .Disclaimer: Use this procedure at your own risk!! I’m not responsible for your mistakes man! :D First, pop your hood and find the diagnostic data port. It is located on the right side of the engine bay near the right strut tower.Unscrew the cap. You will see a big Pac-Man shaped hole and twenty little round holes. What is a Pac-Man? Never mind. We are only concerned with pin 7 and pin 19 (note: the words "pin" and "hole" are used interchangeably in this text). Refer to the picture below to find pins 7 and 19.View attachment 7252What we will be doing in this exercise is connecting pins 7 and 19 with a paperclip for four seconds. This will reset the oil service light. Simple, no? But first, here is the list of pins and what they are supposed to do: Pin Terminal Description1 TD TD Signal2 - Not occupied3 - Not occupied4 - Not occupied5 - Not occupied6 - Not occupied7 SI Service Interval Reset8 - Not occupied9 - Not occupied10 - Not occupied11 - Not occupied12 61 (D+) Generator Charge Indicator13 - Not occupied14 30 Voltage; Hot At All Times15 RXD Diagnostic Data Link16 15S Voltage; Ignition Switch in Run17 - Not occupied18 PGSP Programming Line19 31 Ground20 TXD Diagnostic Data Link[/RIGHT][/RIGHT][/RIGHT][/CENTER] OK, using a paperclip, Bend your paperclip it so it looks like this:View attachment 7253Well it doesn’t have to look exactly like this, but you get the idea. Use pliers if you have to. We want those little loops at the end to maximize the contact with the conductors in the holes of the data port. If you can’t make those little loops at the ends, that’s okay. Just don’t go running around with sharp objects. OK, now you’re ready to reset the oil service light, so turn the ignition key to position II, but don’t start the car. Get out of the car and go to the data port. Always connect pin 7 first. Once you’ve inserted one end into pin 7, insert the other end into pin 19 and hold it there for 4 seconds. Then remove the paperclip. Check the dash and the oil inspection lights should be reset. The reset occurs upon removal of the clip.IMPORTANT: DO NOT HOLD IT THERE FOR LONGER THAN 10 SECONDS or you may inadvertently reset your inspection I/II interval.View attachment 7254 OK, you’re done. It was pretty easy as I promised! wasn’t it?

Not every workshop is equipped with a GT1 or Modic machine.

It's perfectly safe to DIY this.
 
he ehe what a info. feel like i am posting in junior mcgyver wanna be. I think if show this to my customer i don't think they will dare to do it. BTW it is good to have people like marissa. at least there's always a 2nd way if we are tired of it
 
by the way the proper way to reset oil service led is
switch ignition on
connect LED also can use BULB test lamp between terminal 7 of the engine diagnostic connector and earth.
After 3 seconds 5 green LED on the meter panel will illuminate
Switch ignition off
 
usually i would prefer to reset it with launchpad etc etc ....as during this practice i would check for all the faulty codes and also erase it ..... therefore a proper reset is obtained ....

great tips and been there for ages ..... also there is another device like a torch light with a switch above it ..plug it in and then on off the switch ....
 
Thanks for the tip bro. I did my car's coolant change just recently at home. Got the info from pelicanparts.com. Will try to do the oil change myself later too plus the reset.

Cheers
