1.
CHECK SOLENOID VALVE
1)
Ignition "OFF".
2)
Disconnect "A/T SOLENOID VALVE" connector.
3)
Measure resistance between terminal "3" and terminal "6" of the ATM SOLENOID VALVE harness connector.
Specification: Approximately 2.7~3.4 Ω [20 C(68 F)]

Refer to DTC P0743.
GENERAL DESCRIPTION
EE1A17C7
The Automatic transmission changes the gear position of the transmission by utilizing a combination of clutches and
brakes, which are controlled by solenoid valves. This automatic transmission consists of a: LR (Low and Reverse Brake),
2ND (2nd Brake), UD (Under Drive Clutch), OD (Over Drive Clutch), REV (Reverse Clutch), and RED (Reduction Brake,
only for 5 speed transmissions).
The 2ND Brake is engaged in the 2nd gear and 4th gear positions.
DTC DESCRIPTION
E2AC72C5
The TCM checks the Under Drive 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 TCM judges that 2nd Brake drive control solenoid circuit is
malfunctioning and sets this code.
DTC DETECTING CONDITION
EE1D0BD8
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
• Out of available voltage range
Diagnostic Time
• More than 2 seconds
Fail Safe
• Locked in 3rd gear.(Control relay off)
• Open or short in circuit
• Faulty 2ND SOLENOID
VALVE
• Faulty PCM/TCM
