Setting Condition:
The condition in which the voltage of oil temperature sensor is below 0.1V (146 C) and ATF temperature
warning lamp ON in the P or N range lasts for more than 5 minutes.
Or
The vehicle speed exceeds 20 km/h and the voltage of oil temperature sensor exceeds 2.43V (-40 C) for more
than 10 seconds.
Fail Safe:
The lock-up is inhibited, and TCM is controlled ATF temperature 80 C condition as substitute.
When the engine speed is more than 470 rpm for 10 minuets, the lock-up and gear shift to 4th (over-drive) are
allowed.
Possible Cause:
Oil temperature sensor wire open circuit or short circuit.
Oil temperature sensor malfunction.
Power supply wire open circuit, short circuit to battery or short circuit to ground between oil temperature sensor
and TCM terminal B4 (C95).
Ground wire open circuit or short circuit to battery between oil temperature sensor terminal and TCM terminal
B14 (C95).
Poor connection of each connector.
Reference:
Following output voltage and resistance can be measured by circuit tester.

Setting Condition:
The supply voltage is below 10V and the engine speed exceeds 1000 rpm for more than 1 second.
Fail Safe:
When the vehicle is running, the gear position selected at the trouble detection is held and the lock-up is
inhibited.
After the vehicle stopped, all solenoid operations stop (OFF) and the gear is fixed to the 3rd. (In case of fail-safe
valve failure, gear shift to 4th (over-drive) is inhibited.)
Possible Cause:
Alternator or battery malfunction.
Power supply wire open circuit or short circuit to ground between power supply and TCM terminal A1 (C94).
Ground wire open circuit or short circuit to battery between ground location and TCM terminal B5 (C95) or B15
(C95).
Poor connection of each connector.

DIAGNOSIS (JR405E) 7A2-45
Setting Condition:
No range signal is entered from the inhibitor switch with the engine speed over 500 rpm for 2 seconds.
Or
Multiple signals are entered from the inhibitor switch for 1 second.
Fail Safe:
When the vehicle is running, the gear position selected at the trouble detection is held and the lock-up is
inhibited.
After the vehicle stopped, all solenoid operations stop (OFF) and the gear is fixed to the 3rd.
Possible Cause:
Inhibitor switch incorrect adjustment.
Inhibitor switch malfunction.
Open circuit or short circuit to battery between inhibitor switch terminal 2 and TCM terminal A2 (C94), terminal 4
and TCM terminal B19 (C95), terminal 8 and TCM terminal B10 (C95), terminal 5 and TCM terminal B11 (C95),
terminal 1 and TCM terminal A17 (C94), terminal 9 and TCM terminal B2 (B95), or terminal 6 and TCM terminal
B21 (C95), or short between respective harness.
Power supply wire open circuit or short circuit to ground between inhibitor switch terminal 3 and power supply
circuit.
Poor connection of each connector.
