VERIFICATION OF VEHICLE REPAIR
E21BB1F7
After a repair, it is essential to verify that the fault has been corrected.
1.
Connect scantool and select "Diagnostic Trouble Codes(DTCs)" mode.
2.
Using a scantool, Clear DTC.
3.
Operate the vehicle within DTC Enable conditions in General information.
4.
Are any DTCs present?
YES
▶ Go to the applicable troubleshooting procedure.
NO
▶ System performing to specification at this time.

COMPONENT LOCATION

GENERAL DESCRIPTION
E8C28EFB
Variable Force Solenoid (Linear Solenoid) : With the duty control which uses higher frequency(600Hz), instead of the
existing PWM type which adapts low frequency(60Hz) to control, spool valve can be controlled precisely.
In PWM control, the amount of oil flow is determined by the duration of "ON"signal among continuously repeated ON/OFF
signals.
In VFS, the amount is decided by the width of the oil passage.
DTC DESCRIPTION
E7FEEABF
The TCM checks the VFS Control Signal by monitoring the feedback signal from the solenoid valve drive circuit. If an
unexpected signal is monitored (for example, high voltage is detected when low voltage is expected, or low voltage is de-
tected when high voltage is expected), the TCM judges that the Low and Reverse control solenoid circuit is malfunctioning
and sets this code.
DTC DETECTING CONDITION
E7DA9EA8
Item
Detecting Condition
Possible cause
DTC Strategy
• Check voltage range
Enable Conditions
• 18V > Voltage Battery >10V
• VFS SOL Duty ≥ 8.4%
• IG "ON"
• Not Fail Safe Status
Threshold value
• Out of available voltage range
Diagnostic Time
• more than 320msec
Fail Safe
• GRD shord : Locked in 3 rd gear.(Control relay off)
• OPEN or B+ short : not control VFS
• Open or short in circuit
• Faulty VF SOLENOID VALVE
• Faulty PCM/TCM
