Takes a scan tool. I believe you can also use a piece of wire to jump a couple of pins, but don't know how to do it.

Suggest you check the search box at the upper R of each page, or check youtube. Both are immense sources of info.

If the car was manufactured before 6/00, there will be a 20-pin connector next to the right side shock tower. You need to jumper pins 7 and 19. Be very careful in identifying them. If you're not sure about this, buy a reset tool on ebay or Amazon. Make sure it comes with the 20-pin adapter.

1) If you have a reset tool then turn your car key to Position II but do not start the car.
2) Turn the cap counter clock wise on the Data Link Connector and insert the Reset Tool
3) Follow the instructions of your reset tool, different models may have different fuctions however they all create a short in PIN 7 to PIN 19 for a given amount of time.


***8226; OIL Service Reset requires pin 7 and 19 to be closed for 3+ seconds
***8226; INSPECTION Service Reset requires pin 7 and 19 to be closed for 10+ seconds

If you don't have the tool...you can use a wire or needle nosed pliers.

As mentioned above...you need to short pins #7 & #19. This is simple & easy because the pins are identified on the DLC in the engine bay. If you're a careless person & don't look closely to identify the correct pins...you can turn simplicity into a total disaster...SO PAY ATTENTION & select the right pins...consider painting the correct pins for ease of identity in the future. :)

To use a simple wire or needle nosed pliers...you follow the basic instructions below...don't try to improvise...like turn the ignition on furst, then inserting your shorting tool. This gives no room for mistakes in case you accidentally insert tool into wrong pin or touch wrong pin. Also, REMOVE tool & screw cap back ON BEFORE you turn ignition off:
  • open hood & screw cap off of 20 pin DLC
  • insert tool into pins 7 & 19
  • walk back around car to turn ignition to KL 15 (position 2)
  • begin your count...(approximately) 5-10 seconds for OIL SERVICE or 10-15 seconds for INSPECTION
  • pull tool from DLC at appropriate timg interval
  • SCREW DLC CAP BACK ON!!
  • walk back around and turn ignition OFF

When you turn the ignition back on...you should see 5 green LEDS if you are NOT within the mimimum fuel consumption required for resetting. That last statement is for repeat resetters that want to reset the SI display often & repeatedly before consuming the 20% of fuel consumption that causes the individual green LEDs to turn off.



Note pins 7 & 19 have been identified in my pics below to make sure I don't screw up the easy process by selecting the wrong pins accidentally:
