DTC Detecting Condition and Trouble Area

DTC Confirmation Procedure

WARNING

!

 

• When performing a road test, select a place where there is no traffic or possibility of a traffic 

accident and be very careful during testing to avoid occurrence of an accident.

• Road test should be carried out with 2 persons, a driver and tester, on a level road.

 

1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine and warm it up to normal operating temperature.
4) Shift select lever to “N” and “D” range for each 10 seconds.
5) Drive vehicle with 4th in “D” range and lock-up ON for 20 seconds or longer referring to “Automatic Gear Shift 

Table”.

6) Drive vehicle with 2nd or 3rd gear in “D” range, 15 – 20% throttle opening and at vehicle speed of 40 km/h (25 

mile/h).

7) Stop vehicle and turn ignition switch OFF.
8) Repeat Step 3) to 6) one time.
9) Stop vehicle.

10) Check DTC, pending DTC and freeze-frame data.

DTC Detecting Condition

Trouble Area

DTC P0741:
When driving vehicle in “D” range, difference in revolution 
between engine and A/T input (input shaft speed) is larger than 
specification although TCM commanded TCC pressure control 
solenoid to turn ON. (2 driving cycle detection logic)

• Mechanical malfunction of TCC pressure control 

solenoid valve.

• Malfunction of valve body assembly.
• Fluid passage clogged or leaking.
• Torque converter clutch malfunction.

DTC P0742:
When driving vehicle in “D” range, difference in revolution 
between engine and A/T input (input shaft speed) is smaller than 
specification although TCM commanded TCC pressure control

Yes

No

1

Was “A/T System Check” performed?

Go to Step 2.

Go to “A/T System 
Check”.

2

Check TCC pressure control solenoid valve for operation 
referring to “Solenoid Valves (Shift Solenoid-A, Shift 
Solenoid-B, TCC Pressure Control Solenoid and Pressure 
Control Solenoid Inspection”.

Are they in good condition?

Clean fluid passage or 
replace valve body 
assembly.
