DescriptionBCS0011W
A/T fluid temperature sensor detects the A/T fluid temperature and sends a signal to TCM.
CONSULT-II Reference ValueBCS0011X
On Board Diagnosis LogicBCS0011Y
Diagnostic trouble code “BATT/FLUID TEMP SEN” with CONSULT-II or 8th judgement flicker without CON-
SULT-II is detected when TCM receives an excessively low or high voltage from the sensor.
Possible CauseBCS0011Z

(Sensor circuit is open or shorted.)

A/T fluid temperature sensor
DTC Confirmation ProcedureBCS00120
CAUTION:

Always drive vehicle at a safe speed.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.
After the repair, perform the following procedure to confirm that the malfunction is eliminated.
WITH CONSULT-II
1. Start engine.
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Drive vehicle under the following conditions.
SLCT LVR POSI: “D” position
VEHICLE SPEED: Higher than 20 km/h (12 MPH)
4. If DTC is detected, go to AT- 11 2 , "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions.
Selector lever position: “D” position
Vehicle speed: Higher than 20 km/h (12 MPH)
3. Perform self-diagnosis. Refer to AT- 7 6 , "
Diagnostic Procedure Without CONSULT-II" .
4. If the check result is NG, go to AT- 11 2 , "
