PCM/TCM control Damper clutch perpomence by supplied oil pressue.
Damper clutch is for fuel reduction by decreasing oil pressue component's resistance in T/C.
This code is set when circuit open or short detected by PCM/TCM.
Item
Detecting Condition
Possible Cause
DTC Strategy
Check ability(Torque converter is opened & sticked)
? Torque converter clutch : TCC
Circuit open or short
TCC solenoid fault
PCM/TCM
Enable Conditions
Completely opened or closed
Gaer tightening
After change of speed > 0.3sec
10V < Solenoid supplied power < 16V
Threshold value
50mA = Feedback current(Circuit short) = 550mA at operating
50mA > Feedback current (Circuit open ) at operating
Detecting Time
More than 0.2sec
Fail safe
Locked into 4th gear
Working temperature : -40?~150?
Internal resistance : 5.1 ± 0.3 O( 25? normal temperature )
