MALFUNCTION IN WATER TEMPERATURE RECEIVER GAUGE
WIRING DIAGRAM
INSPECTION PROCEDURE
HINT:
The ECM sends information on the water temperature sensor to the meter through the Bean. If there is on
open or short circuit in the water temperature sensor circuit, the ECM outputs DTCs. Perform troubleshooting
with the ºEngine systemº.
1 READ VALUE OF HAND±HELD TESTER
(a) Operate the hand±held tester according to the steps on the display and select ºDATA LISTº.

3. CHECK DIAGNOSIS
(a) Using the hand±held tester, check for DTCs.
NOTICE:
Hand±held tester only:
When the diagnosis system is switched from normal mode to check mode, all the DTCs and freeze
frame data recorded in normal mode are erased. So before switching modes, always check the DTCs
and freeze frame data, and make a note of them.
(1) Prepare the hand±held tester.
(2) Connect the hand±held tester to the DLC3 under the instrument panel lower pad.
(3) Turn the ignition switch ON and push the hand±held tester switch ON.
(4) Use the hand±held tester to check for DTCs and freeze frame data, and make a note of them
(For operating instructions, see the hand±held tester instruction book).
(5) Confirm the details of the DTCs.
(b) Either of the following procedures will erase the DTCs and freeze frame data.
(1) Operating the hand±held tester to erase the codes (See the hand±held tester instruction book
for operating instructions).
(2) Disconnecting the battery terminals or ECU±B fuse.
4. DATA LIST
HINT:
Using the DATA LIST displayed on the hand±held tester, you can read the value of the switch, sensor, actua-
tor, etc. without parts removal. Reading the DATA LIST as the first step of troubleshooting is one way to short-
en the labor time.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST, according to the display on the tester.
