A/T TCC S/V FUNCTION (LOCK-UP)

A/T TCC S/V FUNCTION (LOCK-UP)

Description

INFOID:0000000001713096

• This malfunction will not be detected while the OD OFF indicator lamp is indicating another self-diagnosis

malfunction.

• This malfunction is detected when the A/T does not shift into fourth gear position or the torque converter

clutch does not lock-up as instructed by the 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,
malfunctioning oil pump or torque converter clutch, etc.

CONSULT-III Reference Value in Data Monitor Mode

INFOID:0000000001713097

Remarks: Specification data are reference values.

On Board Diagnosis Logic

INFOID:0000000001713098

• Diagnostic trouble code “A/T TCC S/V FNCTN” with CONSULT-III is detected when A/T cannot perform

lock-up even if electrical circuit is good.

• 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 much lower than the position (4th) supposed by TCM, the slip ratio will be much
less than normal. In case the ratio does not reach the specified value, TCM judges this diagnosis malfunc-
tion.
This malfunction will be caused when shift solenoid valve B is stuck closed.

• 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 closed: 1, 2, 2 and 1* positions to each gear position
above
*: “A/T TCC S/V FNCTN” is detected.

Possible Cause

INFOID:0000000001713099

• Line pressure solenoid valve
• Torque converter clutch solenoid valve
• Each clutch
• Hydraulic control circuit

DTC Confirmation Procedure

INFOID:0000000001713100

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-III

1.

Start engine and select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.

2.

Touch “START”.

3.

Make sure that output voltage of A/T fluid temperature sensor is within the range below.
FLUID TEMP SE: 0.4 - 1.5V
If out of range, drive vehicle to decrease voltage (warm up the fluid) or stop engine to increase voltage
(cool down the fluid).

4.

Select “TCC S/V FNCTN P0744” of “DTC WORK SUPPORT” mode for “TRANSMISSION” with CON-
SULT-III and touch “START”.

Accelerate vehicle to more than 80 km/h (50 MPH) and maintain the following conditions continuously
until “TESTING” has turned to “COMPLETE”. (It will take approximately 30 seconds after “TESTING”
shows.)
THROTTLE POSI: 1.0/8 - 2.0/8 (at all times during step 4)
SLCT LVR POSI: “D” position
TCC S/V DUTY: More than 94%
VEHICLE SPEED: Constant speed of more than 80 km/h (50 MPH)

-

Make sure that “GEAR” shows “4”.

-

For shift schedule, refer to 

XX-XX, "*****"

.

-

If “TESTING” does not appear on CONSULT-III for a long time, select “SELF-DIAG RESULTS”. In
case a DTC other than “A/T TCC S/V FNCTN” is shown, refer to 

XX-XX, "*****"

.

6.

Make sure that “OK” is displayed. (If “NG” is displayed, refer to “DIAGNOSTIC PROCEDURE”.)
Refer to 

TM-409, "Diagnosis Procedure"

.

Refer to 

XX-XX, "*****"

Diagnosis Procedure

INFOID:0000000001713101

1.

CHECK SHIFT-UP (D

3

 TO D

4

)

During 

XX-XX, "*****"

.

Does A/T shift from D

3

 to D

4

 at the specified speed?

YES

>> GO TO 11.

NO

>> GO TO 2.

2.

CHECK LINE PRESSURE

Perform line pressure test. Refer to 

XX-XX, "*****"

.

OK or NG

OK

>> GO TO 3.

NG

>> GO TO 6.

3.
