DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

1) Connect scan tool to DLC with ignition switch OFF, if available.
2) Clear DTC in TCM memory.
3) Start engine.
4) Keep engine running at idle speed in “P” range for 10 seconds or more.
5) Check DTC.

36) Remove 2nd brake gasket (1).
37) Measure O/D and 2nd coast brake piston stroke.
If piston stroke exceeds specification, inspect and
replace plates and discs.
• Measure dimension “a” from mating surface of
transaxle case to O/D and 2nd coast brake rear
plate (1) using straightedge and micrometer
caliper.
• Measure dimension “b” from O/D and 2nd coast
brake piston (2) to rear cover assembly mating
surface using straightedge and micrometer
caliper.
• Calculate piston stroke from measured value of
dimensions “a” and “b”.
• Piston stroke = “a” – “b”
O/D and 2nd coast brake piston stroke
Standard: 0.65 – 1.05 mm (0.026 – 0.041 in.)
CAUTION!
When brake disc, retaining plate, separator
plate and/or rear plate of O/D and 2nd coast
brake have been replaced, all learned
contents, which have been stored in TCM
memory by executing learning control,
should be initialized referring to “Learning
Control Initialization”.
Neglecting this initialization may cause
excessive shift shock.

38) Remove forward and reverse clutch assembly (1).
39) Remove intermediate shaft thrust bearing front race
(1), thrust bearing (2) and rear race (3) from forward
and reverse clutch assembly (4).
NOTE
If intermediate shaft thrust bearing and/or
races are not found on forward and reverse
clutch assembly, they may have been left in
transaxle.

3) Check side clearance of both gears.
Using a straightedge (1) and a feeler gauge (2),
measure side clearance between gears and pump
body.
If clearance exceeds its standard value, replace oil
pump assembly.
Side clearance between gears and oil pump body
Standard: 0.02 – 0.05 mm (0.0008 – 0.0019 in.)
4) Using special tool, measure stator shaft bush (1)
bore.
If measured stator shaft bush bore is out of
specifications, replace oil pump assembly with new
one.

assembly (2), then ensure that direct clutch
assembly turns smoothly.
If unsmooth rotation or noise are found in oil pump
assembly, replace oil pump assembly with new one.
This check should also be done to input shaft
assembly and replace input shaft assembly if
necessary.
6) Using special tool, measure oil pump body bush
bore.
If measured oil pump body bush (1) bore is out of
specifications, replace oil pump assembly with new
