DTC P0741:00

TCC stuck off

DETECTION CONDITION

•  The PCM detects that difference between the engine speed and input shaft speed is 100 rpm or more for 5 s when the following conditions are met.

―  Gear position: 4GR

―  Vehicle speed: 60—100 km/h {38.0—62.1 mph}

―  TCC operation: On

―  Shift solenoid A duty ratio: 99.2% or more

Diagnostic support note

•  The MIL does not illuminate.

•  The AT warning light illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  PENDING CODE is not available.

•  FREEZE FRAME DATA is not available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Deteriorated ATF

•  ATF level low

•  Solenoid valve malfunction

―  Pressure control solenoid

―  Shift solenoid A

―  Shift solenoid B

―  Shift solenoid C

―  Shift solenoid D

―  Shift solenoid E

•  Line pressure malfunction

•  Control valve body malfunction

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	INSPECT ATF CONDITION • Inspect the ATF condition. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [FN4A-EL].) • Is it normal?	Yes	Go to the next step.
2		No	Replace the ATF, then go to Step 7. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [FN4A-EL])
3	INSPECT ATF LEVEL • Inspect the ATF level. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [FN4A-EL].) • Is it normal?	Yes	Go to the next step.
3		No	Add ATF to the specified level, then go to Step 7. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [FN4A-EL])
4	INSPECT SOLENOID VALVE • Inspect the following solenoid valves: (See SOLENOID VALVE INSPECTION [FN4A-EL].) ― Pressure control solenoid ― Shift solenoid A ― Shift solenoid B ― Shift solenoid C ― Shift solenoid D ― Shift solenoid E • Is there any malfunction?	Yes	Replace the solenoid valve, then go to Step 7. (See SOLENOID VALVE REMOVAL/INSTALLATION [FN4A-EL].)
4		No	Go to the next step.
5	INSPECT LINE PRESSURE • Perform the “Line Pressures Test”. (See MECHANICAL SYSTEM TEST [FN4A-EL].) • Is there any malfunction?	Yes	Repair or replace malfunctioning part according to test result, then go to Step 7.
5		No	Go to the next step.
6	INSPECT CONTROL VALVE BODY • Remove the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [FN4A-EL].) • Disassemble the control valve body. • Inspect the following parts: ― Shift valve ― Return spring ― Hydraulic passage • Is there any malfunction?	Yes	Repair or replace malfunctioning part according to inspection result, then go to next step.
6		No	Replace the transaxle, then go to the next step. (See AUTOMATIC TRANSAXLE REMOVAL/INSTALLATION [FN4A-EL].)
7	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC using the M-MDS. • Perform the following procedure to ensure that the DTC has been resolved: 1. Drive the vehicle under the following conditions for 5 s or more. ― 4GR ― Vehicle speed: 60—100 km/h {38.0—62.1 mph} ― TCC operation: On • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [FN4A-EL].)
7		No	Go to the next step.
8	VERIFY NO DTCs ARE PRESENT • Perform the “Reading DTCs Procedure”. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FN4A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FN4A-EL].)
8		No	DTC troubleshooting completed.
