Checking Distributor Position

CHECKING DISTRIBUTOR POSITION
To verify correct distributor rotational position, the DRB scan tool must be used.

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.

1. Connect DRB scan tool to the Data Link Connector. The data link connector is located in passenger compartment, below and to left of steering column.
2. Gain access to SET SYNC screen on DRB.
3. Follow directions on DRB screen and start engine. Bring to operating temperature (engine must be in "closed loop" mode).
4. With engine running at idle speed, the words IN RANGE should appear on screen along with 00. This indicates correct distributor position.
5. If a plus (+) or a minus (-) is displayed next to degree number, and/or the degree displayed is not zero, loosen but do not remove distributor holddown clamp bolt. Rotate distributor until IN RANGE appears on screen. Continue to rotate distributor until achieving as close to 0 ° as possible. After adjustment, tighten clamp bolt to 22.5 Nm (200 in. lbs.) torque.

The degree scale on SET SYNC screen of 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 distributor will have no effect on ignition timing. All ignition timing values are controlled by powertrain control module (PCM).

After testing, install air cleaner assembly.
