Component Location

General Description

PCM/TCM control Pressure control solenoid valve by changed current for reducing shift shock.

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	• Monitoring voltage range(Circuit open/short check)	※ Pressure Control Solenoid Valve : PCSV(LP. VFS) • Circuit open or short • PCSV • 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
