PINION FACTOR SETTING
NOTE: This procedure must be performed if the PCM has been replaced with a NEW or replacement unit. Failure to perform this procedure will result
in an inoperative or improperly calibrated speedometer.
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 (final drive and tires) available. Pinion Factor allows the technician to set the Powertrain Control Module initial setting so that the
speedometer readings will be correct. To properly read and/or reset the Pinion Factor, it is necessary to use a scan tool.
1. Plug the scan tool into the diagnostic 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 scan tool screen.
