Component Location

General Description

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.

DTC Description

This code is set when circuit open or short detected by PCM/TCM.

DTC Detecting Condition

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
