FAIL-SAFE FUNCTION [AW6A-EL, AW6AX-EL]
id050211100600
• In the fail-safe function, minimum vehicle drivability is obtained by changing the signals that are determined to
be malfunctions by the malfunction detection function to the preset values, and limiting TCM control.
DTC
No.

Detection condition Fail-safe TCC
P0220
Accelerator pedal position
signal error
• If the accelerator pedal position signal
from the PCM, which is transmitted
using the CAN communication, is
invalid and the condition has
continued for 500 ms or more.
• Inhibits learning control
• Inhibits TCC control
• Inhibits TCC, slip control
• inhibits adaptive shift
control
• Fixes the accelerator pedal
position open signal at
18.8 %
Enabled
P0601 Flash ROM malfunction
• Flash ROM (in TCM) internal circuit
malfunction is detected.
• Emergency mode 1 Disabled
P0603 EEPROM malfunction
• Different numeric values for
EEPRROM and RAM (in TCM) are
detected.
• TCM uses the default
value as the initial value for
EEPROM
Enabled
P0604 RAM malfunction
• RAM (in TCM) read/write error is
detected.
• Emergency mode 1 Disabled
P0706
Transaxle range (TR)
switch circuit range/
performance
• TCM detects stuck TR switch when
ignition switch is at ON position.
• Emergency mode 1
• Locks in D range, 3GR, if
the counter drive gear
(output) speed signal
(VSS) is 0 rpm
• Locks start lock signal
Disabled
P0707
Transaxle range (TR)
switch circuit low input
• TR switch position voltage input to
TCM is less than 0.127 V when
ignition switch is at ON position.
• Emergency mode 1
• Locks in D range, 3GR, if
the counter drive gear
(output) speed signal
(VSS) is 0 rpm
• Locks start lock signal
Disabled
P0708
Transaxle range (TR)
switch circuit high input
• TR switch position voltage input to
TCM is 4.84 V or more when ignition
switch is at ON position.
• Emergency mode 1
• Locks in D range, 3GR, if
the counter drive gear
(output) speed signal
(VSS) is 0 rpm
• Locks start lock signal
Disabled
P0711
Transaxle fluid
temperature (TFT) sensor
malfunction (stuck)
• Change in ATF temperature cannot
be detected for 15 min or more when
driving in D range.
• Inhibits TCC control
• Inhibits TCC, slip control
• Inhibits self learning
control
• Fixes ATF temperature
value at 80 °C {176 °F}
Disabled
P0712
Transaxle fluid
temperature (TFT) sensor
circuit malfunction (short to
ground)
• TCM detects ATF temperature of 200
°C {392 °F} or more.
• Inhibits TCC control
• Inhibits TCC, slip control
• Inhibits self learning
control
• Fixes ATF temperature
value at 80 °C {176 °F}
Disabled
P0713
Transaxle fluid
temperature (TFT) sensor
circuit malfunction (short to
power/open circuit)
• TCM detects ATF temperature of less
than -43 °C {-45.4 °F} when engine is
warmed-up and running.
• Inhibits TCC, slip control
• Inhibits self learning
control
• Fixes ATF temperature
value at 80 °C {176 °F}
Disabled
P0717
Input/turbine speed sensor
circuit malfunction (open
circuit/short circuit)
• Turbine speed signal is not input
during vehicle speed signal 24 pulse
period when driving in D range at 20
km/h {12 mph} or more.
• Normal turbine speed signal is not
input.
• Emergency mode 1 Disabled
