Fail Safe Table

WARNING: This page is about a different variant/trim than selected.

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 P0707	34	Transmission range sensor or its circuit	In case of circuit open, TCM control is performed as "D" range. In case of circuit short (In case that 2 or more sensor signals are inputted), TCM control is performed in following priority order. N > R > L > 2 > D > P
P0712 P0713	36 38	Transmission fluid temperature sensor or its circuit	Line pressure raising control at low A/T fluid temperature is inhibited.
P0717	37	Input shaft speed sensor or its circuit	Gear position is fixed according to select lever position as shown in the following R: Reverse D: 4th 2: 3rd L: 1st Line pressure control which defuses select shock is inhibited. Lock-up function is inhibited to operate. Reverse control operation, which inhibits reverse driving at "R" range while vehicle runs forward at more than 7 km/h (4 mile/h), is inhibited. Torque reducing requirement to ECM (torque reduction control) is inhibited.
P0722	31	Output shaft speed sensor or its circuit	Gear position is fixed according to select lever position as shown in the following R: Reverse D: 4th 2: 3rd L: 1st Line pressure control which defuse select shock is inhibited. Lock-up function is inhibited to operate. Reverse control operation, which inhibit reverse driving at "R" range while vehicle runs forward more than 7 km/h (4 mile/h), is inhibited.
P0727	35	Engine speed signal circuit
P0962 P0963	41 42	Pressure control solenoid valve or its circuit	Power supply to shift solenoid, TCC solenoid and pressure control solenoid valve is cut. Gear position is fixed according to select lever position as shown in the following R: Reverse D: 4th 2: 3rd L: 1st Lock-up function is inhibited to operate.
P0973 P0974	21 22	Shift solenoid valve-A or its circuit
P0976 P0977	23 24	Shift solenoid valve-B or its circuit
P1702	52	TCM
P1700	32 33	Throttle position signal circuit	Gear position is fixed according to select lever position as shown in the following R: Reverse D: 4th 2: 3rd L: 1st Lock-up function is inhibited to operate. Torque reducing requirement to ECM (torque reduction control) is inhibited.
P1709	51	Engine coolant temperature signal circuit	Engine coolant temperature is assumed as normal operating temperature, and controls of up-shift to 4th and lock-up are released from inhibition.
P1730	64	Engine torque signal circuit	Gear position is fixed according to select lever position as shown in the following R: Reverse D: 4th 2: 3rd L: 1st Line pressure control which defuses select shock is inhibited. Lock-up function is inhibited to operate. Reverse control operation, which inhibits reverse driving at "R" range while vehicle runs forward at more than 7 km/h (4 mile/h), is inhibited. Torque reducing requirement to ECM (torque reduction control) is inhibited.
P1740	75	Cruise control signal circuit	O/D and lock-up off control by cruise control signal is inhibited.
P1895	27	Torque reduction signal circuit	Torque reducing requirement to ECM (torque reduction control) is inhibited.
P2763 P2764	25 26	TCC solenoid valve or its circuit	Lock-up function is inhibited to operate. Up-shift to 4th gear is inhibited when A/T fluid temperature is 150 °C (302 °F) or higher. When TCC solenoid valve circuit open or shorted to power circuit, and vehicle speed is less than 10 km/h (6 mile/h), gear position is fixed in 1st gear for prevention of engine stall.
