DTC Detecting Condition and Trouble Area
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 tester, on a level road.

1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine and warm it up to normal operating temperature.
4) Drive vehicle with 3rd or 4th gear in “D” range and slip c ontrolled lock-up ON for 20 seconds or longer referring to
“Automatic Gear Shift Table”.
5) Stop vehicle.
6) Check DTC, pending DTC and freeze-frame data.
DTC Troubleshooting DTC detecting condition
Trouble area
The acceleration slip control function stops when the variation in the output
revolution speed of the specified amp litude and specified cycle is detected
within a specified period of time. When t he specified variation is not detected
after the acceleration slip control stops. • Mismatching ATF

19) Remove transaxle case plug (1).
20) Remove torque converter housing bolts.
21) Remove torque converter housing (1) while tapping
around it lightly with plastic hammer.
22) Remove breather hose (1).
23) Remove breather union (2).
24) Measure input shaft thrust play. Apply dial gauge onto input shaft end (1) and
measure thrust play of input shaft.
When input shaft thrust play is out of specification,
select input shaft front th rust bearing with proper
thickness from among the list below and replace it.

2) Check tip clearance of both drive and driven gears.Using a feeler gauge, m easure clearance between
drive and driven gear tips. If clearance exceeds its
standard value, replace oil pump assembly.
Tip clearance between oil pump drive gear and
oil pump driven gear
Standard: 0.07 – 0.15 mm (0.0028 – 0.0059 in.)
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.
Special tool
(A): 09900–20605
Stator shaft bush bore
Standard: 18.424 – 18.450 mm (0.7254 – 0.7264
in.) 5) Install direct clutch asse
mbly (1) to stator shaft
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 o il pump assembly with new
one. Torque converter also needs to be checked.
Replace torque converter, if necessary.
Special tool
