TCM RESETTING
(1) Disconnect the negative battery cable from the
before replacing the transaxle out overhaul.
(2) After work has been completed, check
trouble codes (DTC). If DTC 12 (“Battery power was
disconnected since last power has been
generated, this DTC must be cleared. Furthermore, select “Special function” on the scan tool
and then set the scan tool to Quick Learn mode (car ry
out this operation from the scan tool screen). Then input
the clutch volume index into the
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.
Note that new
do not a tire size
already input.

TRANSAXLE RANGE SENSOR CONTINUITY
CHECK
(1) Disconnect the transaxle range sensor connector.
(2) Check the continuity between sensor terminals a nd body
ground (and terminals while shifting the
lever at each position. The continuity between sensor
terminals and body ground (and terminals
should
be as shown in the table below.

(3) If there is a defect, replace the transaxle ran ge sensor.
OIL TEMPERATURE SENSOR CONTINUITY
CHECK
(1) Disconnect thetransaxle range sensor connector.
(2) Measure the resistance between terminals 2-3 an d check
that the values are as shown in the table below.
Oil temperature Resistance value

(3) If the values are outside the standard values, replace
the transaxle range sensor.
