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.)

Overrun clutch solenoid valve
DTC Confirmation ProcedureBCS0011K
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 the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Start engine.
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 , "
Diagnostic Procedure Without CONSULT-II" .
4. If the check result is NG, go to AT- 1 0 2 , "
Diagnostic Procedure" .

OVERRUN CLUTCH SOLENOID VALVE

Data are reference value and are measured between each terminal and ground.
Diagnostic ProcedureBCS0011M
1. CHECK INPUT SIGNAL
With CONSULT-II
1. Start engine.
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out the value of “OVERRUN/C S/V” while driving.
Check the value changes according to driving speed.
Without CONSULT-II
1. Start engine.
2. Check voltage between TCM connector terminal and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
