DESCRIPTION
The ECM uses the shift solenoid valves SC and SL to switch control of the shift solenoid valve SLU between forward and reverse clutch control and lock-up control in response to driving conditions.
HINT:
If DTC P0741 is stored after the engine has stalled, the lock-up shift solenoid valve (shift solenoid valve SL) may be malfunctioning.

Torque Converter Clutch Circuit Performance or Stuck OFF
|
Any of the following conditions are met (2-trip detection logic):
-
When the ECM sends a lock-up OFF command and turns the shift solenoid valves SC and SL OFF, the difference between the engine speed (NE) and input turbine speed (NT) is 25 rpm or less for 1 second or more.
-
When the ECM turns the shift solenoid valves SC and SL ON, the difference between the input turbine speed (NT) and primary pulley speed (NIN) is 300 rpm or more for 1 second or more.
-
While the vehicle is driven, a lock-up ON command is sent, but lock-up control is not performed for 1 second or more.

MONITOR DESCRIPTION
When performing lock-up control (on/off) of the torque converter, the ECM compares the transmission revolution sensor (NT) output speed and engine speed (NE) to detect mechanical malfunctions in the shift solenoid valves SL and SC.
If the torque converter does not lock-up while a lock-up ON command is being sent, the ECM detects it as a mechanical malfunction of the shift solenoid valve SLU.
If the difference between the engine speed (NE) and transmission revolution sensor (NT) output speed or transmission revolution sensor (NIN) output speed and transmission revolution sensor (NT) output speed is outside of the threshold, the ECM detects the malfunction, illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
-
After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
-
When clearing the permanent DTCs, refer to the Clear Permanent DTC procedure.
Click here
-
Connect the Techstream to the DLC3.
-
Turn the ignition switch to ON and turn the Techstream on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the ignition switch off and wait for 2 minutes or more.
-
Turn the ignition switch to ON and turn the Techstream on.
-
Start the engine.
-
Drive the vehicle and confirm the lock-up on and off conditions according to Road Test. [*1]

[*1]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
-
Stop the vehicle.
-
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
-
Input the DTC: P0741, P075B or P2757.

CAUTION / NOTICE / HINT
CAUTION:
-
Strictly observe posted speed, limits, traffic laws and road conditions.
-
Do not drive the vehicle with the cable of the Techstream contacting the pedals, shift lever or steering wheel.
-
Driving the vehicle with the cable of the Techstream contacting these areas could impede vehicle control, resulting in a serious accident.
-
Do not operate the Techstream while driving the vehicle.
-
Operating the Techstream while driving the vehicle will prevent you from paying sufficient attention to vehicle surroundings, and could result in a serious accident.

Lock-up control will not operate when the CVT fluid temperature is 40°C (104°F) or less and the vehicle speed is 60 km/h (37 mph) or less, or when the CVT fluid temperature is 5°C (41°F) or less.
-
Lock-up control will not operate when the engine coolant temperature is 30°C (86°F) or less.
-
The lock-up OFF vehicle speed may vary depending on electrical load, and air conditioning and brake operation.
(a) Connect the Techstream to the DLC3.
(b) Start the engine.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Data List / Engine Speed, SPD (NT), SPD (NIN), Lock Up, SL Solenoid Status and Solenoid (SC).
