Scan Tool DataS6RW0D5104008
As the data values given in the following table are standard values estimated on the basis of values obtained from the
normally operating vehicles by using a scan tool, use them as reference values. Even when the vehicle is in good
condition, there may be cases where the checked value does not fall within each specified data range. Therefore,
judgment as abnormal should not be made by checking with these data alone.
Also, condition in the following table that can be checked by the scan tool are those detected by TCM and output from
TCM as commands and there may be cases where the automatic transaxle or actuator is not operating (in the
condition) as indicated by the scan tool.
NOTE
The following scan tool data related to automatic transaxle can be checked only by communicating
with TCM.

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 and start engine.
3) Increase engine coolant temperature to about 50 °C (122 °F) and more.
4) Start vehicle and increase vehicle speed to about 20 km/h (12 mile/h) for 10 minutes or more.
5) Stop vehicle and check DTC.
DTC Troubleshooting
Step Action Yes No
1Was “A/T System Check” performed?Go to Step 2. Go to “A/T System
Check”.
2Check transmission fluid temperature circuit for open
1) Turn ignition switch OFF.
2) Disconnect TCM connectors from TCM.
3) Check for proper connection to transmission fluid
temperature sensor at terminals “C06-11” and “C06-12”.
4) If OK, check continuity between terminals “C06-11” and
“C06-12” of disconnected harness side TCM connector.
Is continuity indicated?Go to Step 3. “LT GRN” or “ORN”
circuit open.
3Check transmission fluid temperature circuit for IG
short
1) Cool down A/T fluid temperature under ambient
temperature.
2) Connect TCM connectors to TCM with ignition switch
OFF.
3) Turn ignition switch ON.
4) Measure voltage between terminal “C06-11” of TCM
connector and ground.
Is it 4.6 V or more?“LT GRN” circuit shorted
to power circuit.
If circuit is OK, go to
St ep 4 .Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good TCM and
recheck.
4Inspect transmission fluid temperature sensor
1) Inspect transmission fluid temperature sensor referring
to “Transmission Fluid Temperature Sensor Inspection”.
Is result satisfactory?Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good TCM and
recheck.Replace transmission
fluid temperature
sensor.
