Control Module: Service and Repair
Pinion Factor Setting
STANDARD PROCEDURE - PINION FACTOR SETTING
NOTE: This procedure must be performed if the PCM/TCM 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/TCM must be calibrated to the different
combinations of equipment (final drive and tires) available. Pinion Factor allows the technician to set the Powertrain/ Transmission 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 DRBIII scan
tool.
1. Plug the DRBIII 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 DRBIII scan tool screen.
