DAEWOO V–121 BL4
DIAGNOSTIC TROUBLE CODE (DTC) P0741
TORQUE CONVERTER CLUTCH (TCC) CIRCUIT STUCK
OFF
Conditions for Setting the DTC
S Lockup solenoid is stuck OFF.
S D range selected
S Engine water normal temperature
S 20 seconds have passed since the transaxle was
placed in D.
S Engine revolution is 600 rpm or greater.
S No failure of input speed sensor / engine revolution
/ water temperature signal / solenoid electrical /
ranger sensor / throttle signal
Action Taken When the DTC Sets
S TCM will request the illumination of MIL and store
DTC when TCM detects failures on two consecu-
tive ignition cycles.Conditions for Clearing the DTC
S The TCM turns off the MIL when no further failures
detected for three consecutive ignition cycles.
S The scan tool can clear the DTC from the TCM his-
tory.
S The TCM clears the DTC from the TCM history
memory after forty consecutive warm up cycles
without fault.
Cause of Failure
S Lockup solenoid
S Inside A/T
S Inside valve body
S TCM
