INFOID:0000000005258004

On Board Diagnosis Logic

INFOID:0000000005258005

• This is not an OBD-II self-diagnostic item.

• Diagnostic trouble code “P0725” with CONSULT-III or 16th judgment flicker without CONSULT-III is detected

when TCM does not receive the ignition signal from ECM during engine cranking or running.

Possible Cause

INFOID:0000000005258006

Harness or connectors

(The ECM to the TCM circuit is open or shorted.)

DTC Confirmation Procedure

INFOID:0000000005258007

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. Turn ignition switch “ON” and select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.

2. Start engine and maintain the following conditions for at least 10 consecutive seconds.

VHCL/S SE-A/T: 10 km/h (6 MPH) or more

ACCELE POSI: More than 1/8

SLCT LVR POSI: “D” position 

3. If DTC is detected, go to 

TM-57, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000005258008

1.

CHECK CAN COMMUNICATION LINE

Perform the self-diagnosis. Refer to 

TM-36, "CONSULT-III Function (TRANSMISSION)"

.

Is a malfunction in the CAN communication indicated in the results?

YES

>> Check CAN communication line. Refer to 

TM-46

.

NO

>> GO TO 2.

2.

CHECK DTC WITH TCM

With CONSULT-III

1. Start engine.

2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.

3. While monitoring engine speed, check for engine speed change corresponding to wide-open throttle posi-

tion signal.

OK or NG

OK

>> GO TO 3.

NG

>> Check the ignition signal circuit.

• Refer to 

EC-407, "Diagnosis Procedure"

P0731 1GR INCORRECT RATIO

Description

INFOID:0000000005258009

This malfunction is detected when the A/T does not shift into 1GR 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 Logic

INFOID:0000000005258010

• This is an OBD-II self-diagnostic item.

• Diagnostic trouble code “P0731” with CONSULT-III or 18th judgment flicker without CONSULT-III is detected

when TCM detects any inconsistency in the actual gear ratio.

Possible Cause

INFOID:0000000005258011

• 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 Procedure

INFOID:0000000005258012

CAUTION:
