Fail Safe Operation
• Throttle opening used for line pressure control is assumed
to be 100%.
• Throttle opening used for gear shifting control is assumed to
be 0%.
• After 15 minutes pass from detecting malfunction, engine
coolant temperature is assumed to be 90°C (194°F).
• Upshifting to O/D is inhibited.
• Lock-up function is inhibited to operate.
• Line pressure control at gear shifting is inhibited.
• Torque reducing request to ECM (torque reduction control)
is inhibited.
• Learning control is inhibited.
• Garage shift control is inhibited.
• Power supply for all solenoid valves is cut.
• Gear position is fixed in 3rd gear.
• Line pressure control at gear shifting is inhibited.
• Lock-up function is inhibited to operate.
In case of throttle position signal malfunction:
• 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.
• Lock-up function is inhibited to operate.
• Garage shift control is inhibited.
• Learning control is inhibited.
In case of engine coolant temperature signal malfunction:
• 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.
In case of engine revolution signal malfunction:
• Upshifting to O/D is inhibited.
• Lock-up function is inhibited to operate.
• Line pressure control at gear shifting is inhibited.
• Torque reducing request to ECM (torque reduction control)
is inhibited.
• Garage shift control is inhibited.
• Learning control is inhibited.
• Lock-up function is inhibited to operate.
• Lock-up function is inhibited to operate.
• Vehicle speed is slower than 15 km/h (9 mile/h), gear posi-
tion is fixed in 1st gear for prevention of engine stall.
