AUTOMATIC TRANSAXLE

23C-118

OBD-II DRIVE CYCLE PATTERN

Drive with the vehicle speed 5 km/h (3.1 mph) or 
more for 5 seconds or more.

.

TROUBLESHOOTING HINTS (THE MOST 
LIKELY CAUSES FOR THIS CODE TO BE 
SET ARE:)

• Malfunction of the CAN

• Malfunction of the ECM

• Damaged harness or connector

• Malfunction of the throttle position sensor 

• Malfunction of the TCM

DIAGNOSIS

STEP 1. Check for CAN communication system 
malfunction.
Q: Are the DTC U0001, U0100, U0141, P1705, P1706 set?

YES : Check and repair the CAN communication system.
NO :  Go to Step 2.

STEP 2. Check the throttle position sensor and ECM-side 
main unit and connector wiring.
Q: Is the check result normal?

YES : Go to Step 3.
NO :  Repair or replace the failure section.

STEP 3. Erase the DTC code, and drive the vehicle for a 
while.
Check that the normal code is displayed.
Q: Is the check result normal?

YES : The procedure is complete.
NO :  Replace the TCM.

TSB Revision

AUTOMATIC TRANSAXLE

23C-120

DIAGNOSIS

STEP 1. Is the DTC code for ECM displayed?
Check that the failure related to the engine does not occur.
Q: Is the check result normal?

YES : Go to Step 2.
NO :  Repair or replace the failure section.

STEP 2. Check the throttle position sensor and ECM-side 
main unit and connector wiring.
Q: Is the check result normal?

YES : Go to Step 3.
NO :  Repair or replace the failure section.

STEP 3. Erase the DTC code, and drive the vehicle for a 
while.
Check that the normal code is displayed.
Q: Is the check result normal?

YES : The procedure is complete.
NO :  Return to START.

DTC P1731: 1st Engine Brake Detection

.

DESCRIPTIONS OF MONITOR METHODS

• With the mode other than SPORT MODE and 

with the accelerator angle is smaller than 6/8, the 
correlation between the lock-up and low-reverse 
brake linear solenoid valve control current and 
the low-reverse brake pressure switch ON/OFF is 
abnormal.

.

TROUBLESHOOTING HINTS (THE MOST 
LIKELY CAUSES FOR THIS CODE TO BE 
SET ARE:)

• Transaxle assembly powertrain parts failure

• Malfunction of the valve assembly (Malfunction of 

hydraulic valve and hydraulic switch)

• Malfunction of the TCM

• Malfunction of the lock-up and low-reverse brake 

linear solenoid valve (valve assembly)

• Malfunction of the low-reverse brake pressure 

switch (valve assembly)

• Malfunction of the low clutch pressure switch 

(valve assembly)

• Malfunction of the low clutch linear solenoid valve 

(valve assembly)

• Malfunction of the low-reverse brake shift sole-

noid valve (valve assembly)

• Malfunction of the low clutch, low-reverse brake

DIAGNOSIS

STEP 1. Check the DTC.
Check that P0988 (Low-reverse brake pressure switch) is set.
Q: Is the DTC set?

YES : Check and repair the relevant DTC system.
NO :  Go to Step 2.
