Step A. Locate your vehicle's battery. Disconnect the 12v positive cable (red wire) from battery terminal (+). Leave it disconnect for 10 minutes. While the battery is disconnected, cycle the ignition switch to ON position 3 times.
- Note you've just erased important emissions related data which is invaluable to a smog technician attempting to repair your vehicle.
- You also deleted very important "readiness flag" data which took many driving hours to compile.
Step B. Insure ignition switch is OFF. Reconnect the battery 12v positive cable (red wire) to battery terminal (+).
- You're risking electronic component damage. High voltage spark produced during the reconnection of the positive 12v cable can cause damage to fragile electronic emissions component/s.
Step C. Cycle ignition switch to ON position and wait 1 minute, then start your vehicle. Check Engine Light or Service Engine Soon Light should be reset and turned OFF.
- If you are successful in turning off the check engine light, this means your vehicle has not stored it's emissions data in the ROM section of it's computer and you have just deleted all data pertaining to your vehicle's engine and emissions systems, probably including your radio & system settings.
