INSPECTION PROCEDURE
1 DRIVING TEST
(a) Start the engine.
(b) Turn the ECT SNOW switch ”OFF” (Normal drive mode).
(c) Confirm vehicle response by driving from a parked position to fully depressing the accelerator pe\
dal.
(d) Turn the ECT SNOW switch ”ON” and perform the same check as (c). Confirm that there is a difference between ECT SNOW switch ”ON” and ”OFF”.
HINT:

Driving test should be done on a paved road (a nonskid road).

Make sure not to use the TRAC system when testing a vehicle equipped wit\
h one.
OK:
There is a difference in acceleration between ”ON” and ”OFF”\
.

(a) Connect the connector of pattern select switch.
(b) Disconnect the instrument panel J/B assy (integration
relay) connector.
(c) Measure the resistance between terminal SNOW of instrument panel J/B assy (integration relay) connector
and body ground.

INSPECTION PROCEDURE
HINT:
Using the Intelligent Tester II Data List allows switch, sensor, actuator and other item values to be read with-
out removing any parts. Reading the Data List early in troubleshooting is one way to shorten labor time.
NOTICE:
In the table below, the values listed under ”Normal Condition” are reference values. Do not depend
solely on these reference values when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Intelligent Tester II to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Turn on the tester.
(f) Select the item ”Enter / Power train / Engine and ECT / Data List”.
(g) Follow the instructions on the tester and read the Data List.

HINT:
When DTC P0712 is output and Intelligent Tester II output is 150C (302F) or more, there is a short circuit.
When DTC P0713 is output and Intelligent Tester II output is –40C (–40F), there is an open circuit.
Measure the resistance between terminal THO (OT) and body ground.

  Short circuit
HINT:
If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately set (in 0.5 second).
When P0713 is set, P0711 cannot be detected.
It is not necessary to inspect the circuit when P0711 is set.
