Red LED visiable ECU is on the drive tunnel turn the key to on posistion dash warning lights on.(just before crank) really get your head into the floor gently turn the screwdriver slot clockwise watch flashing both once then both twice and then after 3 flashes (mode 3) gently turn the screwslot back counter clockwise. Now The codes will repete 3 times than go to the next code, after the last code thay will start again. Example one long flash .6 second and two shorter flashes .3 second Is a Code 12 either turn the slot clockwise and run thru mode 5 to clear out all the codes or with the slot counter clockwise turn off the ingnition switch to exit Diagnositc mode. While the LED flashes the check engine light also flashes. Good luck
