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.

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.
CONSULT-II Reference ValueBCS0012C
On Board Diagnosis LogicBCS0012D
Diagnostic trouble code “TURBINE SENSOR” with CONSULT-II or 10th judgement flicker without CONSULT-II
is detected when TCM does not receive the proper voltage signal from the sensor.
Possible CauseBCS0012E

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

A/T 1ST GEAR FUNCTION

A/T 1ST GEAR FUNCTIONPFP:31940
DescriptionBCS00131

This malfunction will not be detected while A/T CHECK indicator lamp is indicating another self-diagnosis
malfunction.

This malfunction is detected when the A/T does not shift into first gear position as instructed by TCM. This
is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such as
control valve sticking, improper solenoid valve operation, etc.
On Board Diagnosis LogicBCS00132

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM
as follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (1st) supposed by TCM, the slip ratio will be more
than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when either shift solenoid valve A is stuck open or shift solenoid valve B is
stuck open.

Gear positions supposed by TCM are as follows.
In case of gear position with no malfunctions: 1 , 2, 3 and 4 positions
In case of gear position with shift solenoid valve A stuck open: 2* , 2, 3 and 3 positions
In case of gear position with shift solenoid valve B stuck open: 4* , 3, 3 and 4 positions to each gear posi-
tion above
*: “A/T 1ST GR FNCTN” is detected.

Diagnostic trouble code “A/T 1ST GR FNCTN” with CONSULT-II is detected when A/T cannot be shifted
to the 1st gear position even if electrical circuit is good.
Possible CauseBCS00133

A/T 2ND GEAR FUNCTION

A/T 2ND GEAR FUNCTIONPFP:31940
DescriptionBCS00136

This malfunction will not be detected while A/T CHECK indicator lamp is indicating another self-diagnosis
malfunction.

This malfunction is detected when A/T does not shift into second gear position as instructed by TCM. This
is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such as
control valve sticking, improper solenoid valve operation, etc.
On Board Diagnosis LogicBCS00137

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM
as follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more
than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve B is stuck open.

Gear positions supposed by TCM are as follows.
In case of gear position with no malfunctions: 1, 2 , 3 and 4 positions
In case of gear position with shift solenoid valve B stuck open: 4, 3* , 3 and 4 positions to each gear posi-
tion above
*: “A/T 2ND GR FNCTN” is detected.

Diagnostic trouble code “A/T 2ND GR FNCTN” with CONSULT-II is detected when A/T cannot be shifted
to the 2nd gear position even if electrical circuit is good.
