(2) After work has been completed, check
trouble codes (DTC). If DTC 12 (“Battery power was

PINION FACTOR WRITING PROCEDURE
REPLACEMENT OR TIRE SIZE
NOTE
With transmissions, the TCM uses the rotation speed
of the transaxle output shaft to calculate the vehicle speed
and cumulative distance
Because of this, it is
necessary to input (or update) the tire size coeffi cient into
the TCM memory after the TCM has been replaced or t he
tire size has been changed.
(1) Select “Special function” on the scan
and then set
the scan tool to Pinion Factor mode (carry out this operation from the scan tool screen). Then input (o r
update) the tire size coefficient the TCM memory.
