AT OIL TEMP Warning Light Display
INSPECTION








DIAGNOSIS:
The AT OIL TEMP warning light circuit is open or shorted.

TROUBLE SYMPTOM:
^ When the ignition switch is turned to ON (engine OFF), AT OIL TEMP warning light does not illuminate normally.

WIRING DIAGRAM:

CHECK FUSE (No. 13).
Remove the fuse (No. 13).
Is the fuse (No. 13) blown out?
Yes
Replace the fuse (No. 13). If replaced fuse (No. 13) is blown out easily, repair short circuit in harness between fuse (No. 13) and combination meter.

No
Go to next step

CHECK HARNESS CONNECTOR BETWEEN COMBINATION METER AND IGNITION SWITCH.
Turn the ignition switch to OFF.
Remove the combination meter.
Turn the ignition switch to ON (engine OFF).
Measure the voltage between combination meter connector and chassis ground.
Connector & terminal
(i11) No. 7 (+) - Chassis ground (-):
Is the voltage more than 9 Volts?
Yes
Go to CHECK OPEN CIRCUIT OF HARNESS

No
Repair the open circuit in harness between combination meter and battery.

CHECK OPEN CIRCUIT OF HARNESS.
Turn the ignition switch to OFF.
Disconnect the connector from TCU.
Measure the resistance of TCU connector between combination meter connector.
Connector & terminal
(B56) No. 13 - (i10) No. 5:
Is the resistance less than 1 Ohms?
Yes
Go to CHECK COMBINATION METER

No
Repair the open circuit in harness between TCM and combination meter, and poor contact in coupling connector.

CHECK COMBINATION METER.
Measure the resistance between combination meter connector and chassis ground.
Connector & terminal
(i10) No. 5 (+) - Chassis ground
Is the resistance less than 1 Ohms?
Yes
Go to CHECK INPUT SIGNAL FOR TCM

No
Repair the ground short circuit in harness between TCM and combination meter.

CHECK INPUT SIGNAL FOR TCM.
Connect the connector to combination meter.
Turn the ignition switch to ON (engine OFF).
Measure the voltage between TCM connector and chassis ground.
Connector & terminal
(B56) No. 13 (+) - Chassis ground (-):
Is the voltage less than 9 Volts?
Yes
Replace the TCM.

No
Replace the combination meter.





OPERATION
When any on-board diagnostics item is malfunctioning, the display on AT OIL TEMP warning light blinks from the time malfunction is detected after starting the engine until ignition switch is turned to OFF. The malfunctioning part or unit can be determined by a DTC during on-board diagnostics operation. Problems which occurred previously can also be identified through the memory function. If the POWER indicator does not show a problem (although a problem is occurring), the problem can be determined by checking the performance characteristics of each sensor using Vehicle Diagnostic Interface. The indicator signal is as shown in the figure.

Execute the inspection if AT OIL TEMP warning light dies not operate normally.
