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).

DIAGNOSIS 7A2-41

•

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.
