sec. or more (1-trip detection logic)
MONITOR DESCRIPTION
The automatic transmission fluid (ATF) temperature sensor converts ATF temperature to an electrical resis-
tance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an
opens or shorts in the ATF temperature circuit. If the resistance value of the ATF temperature is less than
79 W
*1 or more than 156 kW*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will
turn on the MIL and store the DTC.
*1: 150C (302F) or more is indicated regardless of the actual ATF temperature.
*2: -40C (-40F) is indicated regardless of the actual ATF temperature.
HINT:
The ATF temperature can be checked on the OBD II scan tool or hand-held tester display.

of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of
troubleshooting is one method to shorten labor time.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the OBD ll scan tool or Hand-held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of OBD ll scan tool or Hand-held tester.
(f) Select the item º/DIAGNOSIS/ENHANCED OBD ll/DATA LIST/ALL (or ATM)º.
(g) According to the display on tester, read the ºDATA LISTº.

(b) Inspect the DLC3.
The vehicle's ECM uses ISO 9141-2 for communication.
The terminal arrangement of DLC3 complies with SAE
J1962 and matches the ISO 9141-2 format.
Tester connectionConditionSpecified condition
7 (Bus Line) - 5 (Signal ground)During communicationPulse generation
4 (Chassis Ground) - BodyAlways1 W or less
5 (Signal Ground) - BodyAlways1 W or less
16 (B+) - BodyAlways9 to 14 V
HINT:
If your display shows UNABLE TO CONNECT TO VEHICLE
when you have connected the cable of the OBD II scan tool or
hand-held tester to the DLC3, turned the ignition switch ON
and operated the scan tool, there is a problem on the vehicle
side or tool side.
If the communication is normal when the tool is connected
to another vehicle, inspect the DLC3 on the original ve-
hicle.
If the communication is still impossible when the tool is
connected to another vehicle, the problem is probably in
the tool itself, so consult the Service Department listed in
the tool's instruction manual.
(c) Inspect the battery voltage.
Battery Voltage: 11 to 14 V
If voltage is below 11 V, recharge the battery before proceeding.
(d) Check the MIL.
(1) The MIL comes on when the ignition switch is turned
ON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter
(See page BE-63).
(2) When the engine is started, the MIL should go off.
If the lamp remains on, it means that the diagnosis
system has detected a malfunction or abnormality
in the system.

(3) When operating an OBD II scan tool (complying
with SAE J1978) or hand-held tester to erase the
codes, the DTCs and freeze frame data will be
erased. (See the OBD II scan tool's instruction book
for operating instructions.)
(c) When not using the OBD II scan tool or hand-held tester:
Clearing the DTCs.
(1) Disconnecting the battery terminal or remove the
EFI and ETCS fuse from engine room J/B for 60 se-
conds or more.
