CHECK OIL PRESSURE
DA
DR
KKCF212B
1)
Connect oil pressure gauge to "DR" ports.
2)
Ignition "ON" & Engine "OFF".
3)
After connecting scantool and monitor the "TCC SOLENIOD VALVE DUTY" parameter on the scantool data list.
4)
Select 1st gear and accelerate Engine speed to 2500 rpm.
5)
Measure oil pressure.
6)
Is oil pressure value within specification?
Specification : approx. 598.2034KPa(6.1kg/cm²)
YES
▶ Repair TORQUE CONVERTER CLUTCH(REPLACE Torque Converter ) as necessary and go to "Verification
of vehicle repair" procedure.
NO
▶ Replace A/T assembly (possible to BODY CONTROL VALVE faulty) as necessary and Go to "Verification of
vehicle Repair" procedure.

GENERAL DESCRIPTION
E406CFBC
The PCM/TCM controls the locking and unlocking of the Torque Converter Clutch (or Damper Clutch), to the input shaft
of the transmission, by appling hydraulic pressure. The main purpose of T/C clutch control is to save fuel by decreasing
the hydraulic load inside the T/C. The PCM/TCM outputs duty pulses to control the Damper Clutch Control Solenoid
Valve(DCCSV) and hydraulic pressure is applied to the DC according to the DCC duty ratio value. When the duty ratio
is high, high pressure is applied and the Damper Clutch is locked. The normal operating range of the Damper Clutch
Control duty ratio value is from 30%(unlocked) to 85%(locked).
DTC DESCRIPTION
E172CCCE
The PCM/TCM checks the Damper Clutch 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 detected when high voltage is expected) the PCM/TCM judges that DCCSV circuit is malfunctioning and sets
this code.
DTC DETECTING CONDITION
EFAE4AC1
Item
Detecting Condition
Possible cause
DTC Strategy
• Check voltage range
Enable Conditions
• 16V > Voltage Battery >11V
• In gear state(no gear shifting) 500msec is
passed from turn on the relay
• A/T Relay = ON
• Engine state = RUN
Threshold value
• Feedback voltage from DCC control solenoid>
vb-2V and DCC control duty is 100%
Diagnostic Time
• More than 2 seconds
Fail Safe
• Locked in 3rd gear.(Control relay off)
※ TORQUE CON-
VERTER(DAMPER) CLUTCH
: TCC
• Open or short in circuit
• Faulty TCC SOLENOID
VALVE
• Faulty PCM/TCM
