OVERRUN CLUTCH SOLENOID VALVE

OVERRUN CLUTCH SOLENOID VALVEPFP:31940
DescriptionBCS0011G
Overrun clutch solenoid valve is activated by TCM in response to signals sent from PNP switch, 3rd position
switch, vehicle speed and ECM (throttle opening). Overrun clutch operation will then be controlled.
CONSULT-II Reference ValueBCS0011H
On Board Diagnosis LogicBCS0011I
Diagnostic trouble code “OVERRUN CLUTCH S/V” with CONSULT-II or 6th judgement flicker without CON-
SULT-II is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.
Possible CauseBCS0011J

Harness or connector
(Solenoid circuit is open or shorted.)

4. Accelerate vehicle to a speed of more than 10 km/h (6 MPH)
with selector lever in “D” position.
5. Release accelerator pedal completely with selector lever in 3rd
position.
6. If DTC is detected, go to AT- 1 0 2 , "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever position: “3” position
Vehicle speed: Higher than 10 km/h (6 MPH).
3. Perform self-diagnosis. Refer to AT- 7 6 , "

TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionBCS0011O
Torque converter clutch solenoid valve is activated, with the gear in D4 , D3 and 33 , by TCM in response to
signals sent from vehicle speed and the ECM (throttle opening). Lock-up piston operation will then be con-
trolled.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed should not
change abruptly. If there is a big jump in engine speed, there is no lock-up.
CONSULT-II Reference ValueBCS0011P

TURBINE REVOLUTION SENSOR

TURBINE REVOLUTION SENSORPFP:31935
DescriptionBCS0012B
The turbine revolution sensor (power train revolution sensor) detects forward clutch drum rpm (revolutions per
minute). It is located on the input side of the automatic transaxle. The vehicle speed sensor A/T (Revolution
sensor) is located on the output side of the automatic transaxle. With the two sensors, input and output rpms
are accurately detected. The result is optimal shift timing during deceleration and improved shifting.
