If there is a malfunction, the lamp lights up for the time corresponding to the suspect circuit.
Erase Self-diagnosis

In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.

However, this information is erased by turning ignition switch OFF after performing self-diagnostics or by
erasing the memory using the CONSULT-III.

DTC P0731 A/T 1ST GEAR FUNCTIONPFP:31940
DescriptionNCS001SB
This malfunction is detected when the A/T does not shift into 1st gear position as instructed by TCM. This is
not only caused by electrical malfunction (circuits open or shorted) but also by mechanical malfunction such
as control valve sticking, improper solenoid valve operation.
On Board Diagnosis LogicNCS001SC

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0731 A/T 1ST GR FNCTN” with CONSULT-III or 18th judgment flicker without
CONSULT-III is detected when TCM detects any inconsistency in the actual gear ratio.
Possible CauseNCS001SD

Harness or connectors
(Solenoid circuits are open or shorted.)

Input clutch solenoid valve

Front brake solenoid valve

Direct clutch solenoid valve

High and low reverse clutch solenoid valve

Each clutch

Hydraulic control circuit
DTC Confirmation ProcedureNCS001SE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Start the engine and select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Make sure that “ATF TEMP 1” is within the following range.
ATF TEMP 1: 20°C – 140°C
If out of range, drive vehicle to warm ATF or stop engine to cool ATF.
3. Select “1ST GR FNCTN P0731” of “DTC WORK SUPPORT” mode for “TRANSMISSION” with CON-
SULT-III.
4. Drive vehicle and maintain the following conditions.
VEHICLE SPEED: 10 km/h (6 MPH) or more
ACCELE POSI: 0.6/8 or more
ENGINE SPEED: TURBINE REV − 50 rpm or more
TURBINE REV: 300 rpm or more
GEAR: “1” position
MANU MODE SW: ON
5. Keep the current driving status for at least 5 consecutive seconds if CONSULT-III screen changes from
“OUT OF CONDITION” to “TESTING”.
CAUTION:
If “TESTING” does not appear on CONSULT-III for a long time, select “SELF-DIAG RESULTS”. In
case a 1st trip DTC other than P0731 is shown, refer to “AT- 8 6 , "
Display Items List" ”.
If “COMPLETED RESULT NG” is detected, go to AT- 11 6 , "
Diagnostic Procedure" .
If “STOP VEHICLE” is detected, go to the following step.
6. Stop vehicle.
7. Drive vehicle in “D” position allowing it to shift from 1st to 5th gear and check shift timing and shift shock.
–Touch “OK” to complete the inspection when normally shifted from the 1st to 5th gear.
–Touch “NG” when an unusual shift shock, etc. occurs in spite of shifting from the 1st to 5th gear. Go to AT-
52, "ROAD TEST" .
