1.
Connect Scantool.
2.
Engine "ON".
3.
Monitor the "INPUT & OUTPUT SPEED SENSOR" parameter on the scantool.
4.
Accelerate the Engine speed until about 2000 rpm in the 4th gear.
Specification : INPUT SPEED - (OUTPUT SPEED × GEAR RATIO) ≤ 200 RPM

5.
Are "INPUT & OUTPUT SPEED SENSOR" within specifications?
YES
▶ Go to "Component Inspection" procedure.
NO
▶ Check for electrical noise of circuit in INPUT & OUTPUT SPEED SENSOR or replace INPUT & OUTPUT SPEED
SENSOR. Repair as necessary and go to "Verification of Vehicle Repair" procedure.

DTC P0741 TORQUE CONVERTER CLUTCH CIRCUIT - STUCK OFF
GENERAL DESCRIPTION
ECAA9FDC
The PCM/TCM controls the locking and unlocking of the Torque Converter Clutch ( or Damper Clutch ), to the input shaft
of the transmission, by appling hydraulic pressure. The main purpose of T/C clutch control is to save fuel by decreasing
the hydraulic load inside the T/C. The PCM/TCM outputs duty pulses to control the Damper Clutch Control Solenoid Valve(
DCCSV ) and hydraulic pressure is applied to the DC according to the DCC duty ratio value. When the duty ratio is high,
high pressure is applied and the Damper Clutch is locked. The normal operating range of the Damper Clutch Control duty
ratio value is from 30%(unlocked) to 85%(locked).
DTC DESCRIPTION
ED347B7C
The PCM/TCM increases the duty ratio to engage the Damper Clutch by monitoring slip rpms (difference vlaue beteween
engine speed and turbine speed ). To decrease the slip of the Damper Clutch, the PCM/TCM increases the duty ratio
by appling more hyraulic pressure. When slip rpm does not drop under some value with 100% duty ratio, the PCM/TCM
determines that the Torque Converter Clutch is stuck OFF and sets this code.
