P0731 1GR INCORRECT RATIO

Description

INFOID:0000000009267927

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 by mechanical malfunction such as control

valve sticking, improper solenoid valve operation, etc.

DTC CONFIRMATION PROCEDURE

CAUTION:

• “

TM-168, "Diagnosis Procedure"

” must be performed before starting “DTC CONFIRMATION PROCE-

DURE”.

• Never perform “DTC CONFIRMATION PROCEDURE” before completing the repair, which may cause

secondary malfunction.

• Always drive vehicle at a safe speed.

1.

PREPARATION BEFORE WORK

If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at

least 10 seconds, then perform the next test.

P0732 2GR INCORRECT RATIO

Description

INFOID:0000000009267930

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 by mechanical malfunction such as control

valve sticking, improper solenoid valve operation, etc.

CAUTION:

• “

TM-170, "Diagnosis Procedure"

” must be performed before starting “DTC CONFIRMATION PROCE-

DURE”.

• Never perform “DTC CONFIRMATION PROCEDURE” before completing the repair, which may cause

secondary malfunction.

• Always drive vehicle at a safe speed.

CHECK DTC DETECTION

With CONSULT

1. Select “2ND GR FNCTN P0732” in “DTC Work Support” in “TRANSMISSION”.

2. Drive vehicle according to the following conditions.

3. Keep the current driving status for 2 seconds or more if CONSULT screen changes from “OUT OFCONDI-

TION” to “TESTING”.

CAUTION:

When “TESTING” is not indicated on CONSULT for a long time, check “Self Diagnostic Results” in
