Distributor Indexing

CHECKING DISTRIBUTOR 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 passenger compartment, below and to the left of steering column. Gain access to the SET SYNC screen on the DRB.

WARNING: When performing the following test, the engine will be running. Be careful not to stand in line with the fan blades or fan belt. Do not wear loose clothing.

Follow the directions on the DRB screen and start the engine. With the engine running, the words IN RANGE should appear on the screen along with O~. 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 zero, loosen but do not remove the distributor holddown clamp bolt. Rotate the distributor until IN RANGE appears on the screen. Continue to rotate the distributor until achieving as close to 0~ as possible. 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 controlled by the powertrain control module (PCM).

After testing, install air cleaner assembly.
