Fail Safe Table
S5JB0E5104008
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, TCM or its
circuit.

Output Speed Sensor Circuit No Signal • 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 4th gear is inhibited.
• Lock-up function is inhibited to operate.
• Torque reducing request to ECM (torque reduction control) is
inhibited.
• Line pressure control at gear shifting is inhibited.

Torque Converter Clutch Circuit Stuck
On
When vehicle speed is less than 10 km/h (6 mile/h), gear position is
fixed in 1st gear for prevention of engine stall.
