5A-26 Automatic Transmission/Transaxle:
Scan Tool Data
S3RH0A5104009
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.
) P1700

Throttle position signal circuit • Throttle opening used for line pressure control is assumed
to be 100%.
• Throttle opening used for gear shifting control is assumed to
be 0%.
• Upshifting to O/D is inhibited.
• Learning control is inhibited.
• Lock-up function is inhibited to operate.
) P1702 52
TCM • Power supply for all solenoid valves is cut.
• Gear position is fixed in 3rd gear.
)
P1705 51
Engine coolant temperature
signal circuit After 15 minutes pass from detecting malfunction, engine
coolant temperature is assumed to be normal operating
temperature, and controls of overdrive and lock-up is released
from inhibition.
) P1730 64
Engine torque signal circuit • Engine torque is assumed to be that of last value before
detecting malfunction.
• Upshifting to O/D is inhibited.
• Line pressure control at gear shifting is inhibited.
• Torque reduction control, which request ECM to reduce to
generate torque, is inhibited.
• Learning control is inhibited.
)
P1895 27
Torque reduction signal circuit Torque reduction control, which request ECM to reduce to
generate torque, is inhibited.
