  1. With ignition off, connect scan tool to Data Link Connector (DLC). Start engine and allow it to reach normal operating temperature.
    2. NOTE: Camshaft retard offset reading will not be accurate with engine speed less than 1000 RPM.
  2. Increase engine speed to more than 1000 RPM. Using scan tool, monitor CAM RETARD OFFSET. If camshaft retard indicates zero degrees plus or minus 2 degrees, distributor is properly adjusted. Procedure is complete. If camshaft retard is not zero degrees plus or minus 2 degrees, see ADJUSTMENT .
