DTC Detecting Condition and Trouble Area

DTC detecting condition	Trouble area
DTC P0741: When driving vehicle with 3rd or 4th gear in “D” or “3” range, difference in revolution between engine and A/T input (input shaft speed) is lager than specification although TCM commanded TCC solenoid to turn ON. DTC P0742: When driving vehicle with 3rd gear in “D” or “3” range, difference in revolution between engine and A/T input (input shaft speed) is smaller than specification although TCM commanded TCC solenoid to turn OFF.	• Mechanical malfunction of TCC solenoid valve. • Malfunction of valve body assembly. • Fluid passage clogged or leaking. • Torque converter clutch malfunction.

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.

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) Shift select lever to “3” range.

7) Drive vehicle with 2nd or 3rd gear in “D” range, 15 – 20% throttle opening and at vehicle speed of 25 – 40 km/h (16 – 25 mile/h).

8) Stop vehicle and turn ignition switch OFF.

9) Repeat Step 3) to 7) one time.

10) Stop vehicle and check DTC.

Troubleshooting

Step	Action	YES	NO
1	Was A/T System Check performed?	Go to Step 2.	Go to A/T System Check .
2	Check TCC solenoid valve for operation referring to Solenoid Valves (Shift Solenoid Valves, TCC Solenoid Valve and Timing Solenoid Valve) Inspection . Are they in good condition?	Clean fluid passage or replace valve body assembly.	Replace TCC solenoid valve.
