Detection condition
• Vehicle speed signal is not input
during turbine speed signal 16 pulse
period when driving in D range at 20
km/h {12 mph} or more.
• Normal vehicle speed signal is not
input.
• If the engine speed signal from the
PCM, which is transmitted using the
CAN communication, is invalid and
the condition has continued for 500
ms or more.
• Incorrect gear ratio is detected when
driving in D range, 6GR, ATF
temperature is 20 °C {68 °F} or
more, and accelerator opening angle
is 10% or more.
• Engine brake is detected to be not
operating when driving in M range,
1GR, ATF temperature is 20 °C {68
°F} or more, and accelerator opening
angle is 10% or more.
• Incorrect gear ratio is detected when
driving in D range, 1GR, ATF
temperature is 20 °C {68 °F} or
more, and accelerator opening angle
is 10% or more.
• Incorrect gear ratio is detected when
driving in D range, 2GR, ATF
temperature is 20 °C {68 °F} or
more, and accelerator opening angle
is 10% or more.
• Incorrect gear ratio is detected when
driving in D range, 3GR, ATF
temperature is 20 °C {68 °F} or
more, and accelerator opening angle
is 10% or more.
• Incorrect gear ratio is detected when
driving in D range, 4GR, ATF
temperature is 20 °C {68 °F} or
more, and accelerator opening angle
is 10% or more.
• Incorrect gear ratio is detected when
driving in D range, 5GR, ATF
temperature is 20 °C {68 °F} or
more, and accelerator opening angle
is 10% or more.
• Incorrect gear ratio is detected when
driving in R position, ATF temperature
is 20 °C {68 °F} or more, and
accelerator opening angle is 10% or
more.
• Irregular shift control detected when
driving in D range, ATF temperature is
65 °C {149 °F} or more, and counter
drive gear (output) speed is 300 rpm
or more.
• Any of the following conditions are
met when ignition switch is at ON
position:
— 0 V detected at TCM terminal A5
when in D range or R position
— 12 V detected at TCM terminal A5
when in P or N position
