P0732 2GR INCORRECT RATIO

P0732 2GR INCORRECT RATIO

Description

INFOID:0000000005274043

This malfunction is detected when the A/T does not shift into 2GR position as instructed by TCM. This is not
only caused by electrical malfunction (circuits open or shorted) but mechanical malfunction such as control
valve sticking, improper solenoid valve operation.

On Board Diagnosis Logic

INFOID:0000000005274044

• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0732” with CONSULT-III or 19th judgment flicker without CONSULT-III is detected

when TCM detects any inconsistency in the actual gear ratio.

Possible Cause

INFOID:0000000005274045

• 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:0000000005274046

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 – 180

°

C

If out of range, drive vehicle to warm ATF or stop engine to cool ATF.

3.

Select “2ND GR FNCTN P0732” of “DTC & SRT CONFIRMATION” mode for “TRANSMISSION” with
CONSULT-III.

4.

Drive vehicle and maintain the following conditions.
SLCT LVR POSI: “2” position
GEAR: “2” position
ACCELE POSI: 0.6/8 or more
VEHICLE SPEED: 10 km/h (6 MPH) or more
ENGINE SPEED: INPUT SPEED 

−

 50 rpm or more

INPUT SPEED: 300 rpm or more

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 P0732 is shown, refer to “

TM-151, "CONSULT-III Function (TRANS-

MISSION)"

”.

If “COMPLETED RESULT NG” is detected, go to 

TM-175, "Diagnosis 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 1GR to 5GR and check shift timing and shift shock.

-

Touch “OK” to complete the inspection when normally shifted from the 1GR to 5GR.

-

Touch “NG” when an unusual shift shock, etc. occurs in spite of shifting from the 1GR to 5GR. Go to 

TM-

271, "Check Before Engine Is Started"

.

-

Perform 

TM-151, "CONSULT-III Function (TRANSMISSION)"

 when not shifted from the 1GR to 5GR.

(Neither “OK” nor “NG” are indicated.)
