Fail Safe Table

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.

FAIL SAFE CHART

DTC No.	Trouble Area	Fail Safe Operation
P0705	Transmission Range Sensor Circuit Malfunction (PRNDL Input)	TCM control is performed in priority order below. 3 > D > 2 > L > R > N > P Slip controlled lock-up function is inhibited to operate. Reverse control is inhibited. Cruise control function is inhibited to operate. (if equipped with cruise control system)
P0707	Transmission Range Sensor Circuit Low	Range is assumed to be "D" range. Slip controlled lock-up function is inhibited to operate. Reverse control is inhibited. Cruise control function is inhibited to operate. (if equipped with cruise control system)
P0712	Transmission Fluid Temperature Sensor "A" Circuit Low	A/T fluid temperature is assumed to be 80 °C (176 °F). Lock-up function is inhibited to operate. Line pressure control at gear shifting is inhibited.
P0713	Transmission Fluid Temperature Sensor "A" Circuit High
