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
Diagnosis Procedure
INFOID:0000000005258008
1.
CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis. Refer to

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
