1. Open the hood and loosen the retaining nut on the cable clamp running to the negative battery terminal.
2. Slide the clamp off of the negative battery terminal.
3. Wait 1 minute for the Range Rover’s electronic control module to cycle and reset. Then, reconnect the clamp to the negative battery terminal.
4. Tighten the retaining nut on the cable clamp. The airbag light should go out at this point. When it does, you’ll know that the fault code has been erased.
The directions that come with your vehicle are lousy, and the process stinks to. And keep in mind that if you do not press the buttons fast enough, or hold long enough, you must start over. It usually takes a few tries. Here’s how to do it:
1.) Press the TRIP/RESET button to cycle to “SETUP MENU HOLD RESET”.
2.) Now press and hold the button for 2 seconds until “RESET FOR SYSTEM CHECK” is displayed, then release.
3.) Imediately press and hold button for 2 more seconds until “Oil 100% RESET IF NEW” is displayed, then release.
4.) Imediately press button once to display “HOLD RESET IF NEW OIL” and release.
5.) Imediately press and hold button for 2 seconds until “OIL LIFE SET TO 100%” is displayed.
If you have done this dance properly, without delaying too long between steps, you are done. What a pain in the butt just to reset the oil maintenance light!!!
