Pinion Factor Setting

2003 Chrysler 300M V6-3.5L VIN MSECTION Pinion Factor Setting
STANDARD PROCEDURE - PINION FACTOR PROCEDURE
The vehicle speed readings for the speedometer are taken from the output speed sensor. The PCM must be calibrated to the different combinations of equipment available. Pinion Factor allows the technician to set the Powertrain Control Module initial setting so that the speedometer readings will be correct.

This procedure must be performed if the Powertrain Control Module has been replaced. Failure to perform this procedure will result in an inoperative speedometer.

To properly read or reset the Pinion Factor it is necessary to use a DRB scan tool. Perform the following steps with the DRB scan tool to read or reset the Pinion Factor:
1. Plug the DRB scan tool into the data link connector located under the instrument panel.
2. Select the Transmission menu.
3. Select the Miscellaneous menu.
4. Select Pinion Factor. Then follow the instructions on the DRB scan tool screen.
