Fail-Safe Table
S3RH0A5104008
This function is provided by the safe mechanism that assures safe driveability even when the solenoid valve, sensor or
its circuit fails. The following table shows the fail-safe function for each fail condition of sensor, solenoid or its circuit.
DTC No. Trouble area Fail-safe operation

P0705 34
Transmission range sensor or
its circuit • Selected range is set as range shown below.
– In case of circuit open, selected range is assumed to be
“D” range.
– In case of circuit short, selected range is set in priority
order shown below.
D> 2> L> R> N> P
• Lock-up function is inhibited to operate.
• Reverse control operation, which inhibit reverse driving at
“R” range while vehicle runs forward more than 11 km/h (7
mile/h), is inhibited.
• Learning control is inhibited.

Transmission fluid temperature
sensor or its circuit • A/T fluid temperature is assumed to be 200
°
C (392
°
F).
• Upshifting to O/D is inhibited.
• Lock-up function is inhibited to operate.
• Learning control is inhibited.

P0715 14
Input shaft speed sensor or its
circuit • Upshifting to O/D is inhibited.
• Lock-up function is inhibited to operate.
• 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.
) P0720 31
Output shaft speed sensor or
its circuit • Vehicle speed which is calculated by input shaft speed
sensor signal is used for gear shifting control instead of
vehicle speed calculated by output shaft speed sensor /
VSS signal.
• Upshifting to O/D is inhibited.
• Lock-up function is inhibited to operate.
• 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.
) P0725 35
Engine speed signal circuit • 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.
• Lock-up function is inhibited to operate.

TCC solenoid valve or its
circuit • Lock-up function is inhibited to operate.
• When TCC solenoid circuit is shorted to power circuit and
vehicle speed is slower than 15 km/h (9 mile/h), gear
position is fixed in 1st gear for prevention of engine stall.
