P0763
Shift solenoid B circuit
malfunction (open circuit/
short to ground or power
supply)
• Open or short circuit in shift solenoid
B signal system (when the TCM
monitors solenoid output voltage,
voltage that differs from the ON/OFF
signal output by CPU in TCM is
detected).
• Driving restricted to 3GR
• Stops operation of TCC
solenoid valve (OFF).
Disabled
P0766
Shift solenoid C
malfunction (stuck off)
• Large difference between actual gear
ratio and gear ratio set in TCM
N/A Enabled
P0767
Shift solenoid C
malfunction (stuck on)
• Large difference between actual gear
ratio and gear ratio set in TCM
N/A Enabled
P0768
Shift solenoid C circuit
malfunction (open circuit/
short to ground or power
supply)
• Open or short circuit in shift solenoid
C signal system (when the TCM
monitors solenoid output voltage,
voltage that differs from the ON/OFF
signal output by CPU in TCM is
detected).
• Driving restricted to 3GR
• Stops operation of TCC
solenoid valve (OFF).
Disabled
P0841
Oil pressure switch B
circuit malfunction
• When driving, hydraulic pressure
should be generated in the 2-4 brake,
but oil pressure switch B does not
turn on.
• When driving, hydraulic pressure
should not be generated in the 2-4
brake, but oil pressure switch B does
not turn off.
N/A Disabled
P0846
Oil pressure switch C
circuit malfunction
• When driving, hydraulic pressure
should be generated in the high
clutch, but oil pressure switch C does
not turn on.
• When driving, hydraulic pressure
should not be generated in the high
clutch, but oil pressure switch C does
not turn off.
N/A Disabled
P0871
Oil pressure switch F
circuit malfunction
• When driving, hydraulic pressure
should be generated in the low and
reverse brake, but oil pressure switch
F does not turn on.
• When driving, hydraulic pressure
should not be generated in the low
and reverse brake, but oil pressure
switch F does not turn off.
N/A Disabled
P0882 TCM B+ low
• The TCM monitors the voltage of
back-up battery positive terminal at
TCM terminal 1A. If the TCM detects
battery positive terminal voltage 4 V
or less for 100 s or more, the TCM
determines that the backup voltage
circuit has malfunction.
N/A Enabled
P0960
GND return circuit
malfunction
• TCM detects an open circuit in the
GND return signal line from the
solenoid valve.
• Driving restricted to 3GR
• Stops operation of TCC
solenoid valve (OFF).
Disabled
P1759
2-4 brake fail-safe valve
malfunction
• TCM detects 2-4 brake fail-safe valve
malfunction.
N/A Disabled
P1764
Low and reverse brake fail-
safe valve malfunction
• TCM detects low and reverse brake
fail-safe valve malfunction.
N/A Disabled
U0073 CAN bus off • CAN controller damaged.
• CAN communication is
stopped
Disabled
U0100
TCM cannot receive any
signals from the PCM
• TCM cannot receive any signals from
the PCM.
• Driving restricted to 3GR
• Stops operation of TCC
solenoid valve (OFF).
