CHECKING ilSTRIBUTOR POSITION To verify correct distributor rotational position, connect the DRB scan tool to the data link connector.
The data link connector is located in the engine com- partment. Gain access to the SET SYNC screen on
the DRB. WARNING : WHE N PERFORMIN G TH E FOLLOWIN G TEST , TH E ENGIN E WIL L B E RUNNING . B E CARE F U L NO T T O STAN D I N LIN E WIT H TH E FA N BLADE S O R FA N BELT .

This indicates correct distributor position. If a plus (+) or a minus (-) is displayed next to the degree number, and/or the degree displayed is not

the distributor until achieving as close to 0° as pos- sible. After adjustment, tighten clamp bolt to 22.5
N-m (200 in. lbs.) torque. The degree scale on the SET SYNC screen of the DRB is referring to fuel synchronization only. It is not referring to ignition timing. Because of this, do not attempt to adjust ignition timing using this method. Rotating the distributor will have no effect
on ignition timing. All ignition timing values are con- trolled by the powertrain control module (PCM).
