B: ABNORMAL DISPLAY ON AT OIL TEMP
INDICATOR
When any on-board diagnostic item is malfunctioning, the
display on the AT OIL TEMP indicator blinks immediately
after the engine starts.
The malfunctioning part or unit can be determined by a
trouble code during on-board diagnostic operation. Prob-
lems which occurred previously can also be identified
through the memory function.
If the AT OIL TEMP 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 the select monitor.
Indicator signal is as shown in the figure.
WARNING:
Warning can be noticed only when the engine is ini-
tially started.

4. CHECK OUTPUT SIGNAL EMITTED FROM TCM.
1) Connect connectors to TCM and transmission.
2) Lift-up the vehicle or set the vehicle on free roller.
CAUTION:
On AWD models, raise all wheels off floor.
3) Start and warm-up the engine and transmission.
4) Push the TCS OFF switch to ON. (With TCS models)
5) Move selector lever to“D”and slowly increase vehicle
speed to 75 km/h (47 MPH).
6) Measure voltage between TCM connector terminals.
Connector & terminal / Specified voltage:
(B55) No. 5—No. 10 / 8.5 V, or more (when

NOTE:
The speed difference between front and rear wheels may
light either the ABS or the ABS/TCS warning light, but this
indicates no malfunctions. When AT control diagnosis is
finished, perform the ABS or the ABS/TCS memory clear-
ance procedure of self-diagnosis system.
