SHIFT SOLENOID VALVE BPFP:31940
DescriptionBCS00118
Shift solenoid valves A and B are turned ON or OFF by TCM in response to signals sent from PNP switch,
vehicle speed and ECM (throttle opening). Gears will then be shifted to the optimum position.
CONSULT-II Reference ValueBCS00119
On Board Diagnosis LogicBCS0011A
Diagnostic trouble code “SHIFT SOLENOID/V B” with CONSULT-II or 5th judgement flicker without CON-
SULT-II is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.
Possible CauseBCS0011B

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

Shift solenoid valve B

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
On Board Diagnosis LogicBCS0011Q
Diagnostic trouble code “T/C CLUTCH SOL/V” with CONSULT-II or 7th judgement flicker without CONSULT-II
is detected when TCM detects an improper voltage drop when it tries to operate solenoid valve.
Possible CauseBCS0011R

Torque converter clutch solenoid valve

Harness or connector
(Solenoid circuit is open or shorted.)
DTC Confirmation ProcedureBCS0011S
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. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II and
wait at least 1 second.
3. Start engine and maintain the following condition for at least 5
consecutive seconds.
VEHICLE SPEED: 80 km/h (50 MPH) or more
THROTTLE POSI: 0.5/8 - 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.
4. If DTC is detected, go to AT- 1 0 7 , "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle in D
1 → D2 → D3 → D4 → D4 lock-up position.
3. Perform self-diagnosis. Refer to AT- 7 6 , "
