Octane Adjust Shorting Bar

The octane adjust shorting bar is used to retard spark. Removing the shorting bar from the in-line connector will retard spark about 3 degrees. A diagnostic trouble code will set if Octane Adjust Shorting Bar is removed, or if an open circuit is present. DO NOT remove shorting bar unless directed to by a technical service bulletin.
