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.

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.
