GENERAL DESCRIPTION
E331DF52
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 OD Clutch is engaged in the 3rd gear and 4th gear positions.
DTC DESCRIPTION
EC62EBFF
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 the OVER DRIVE CLUTCH drive control solenoid
circuit is malfunctioning and sets this code.
DTC DETECTING CONDITION
EAECAFE2
Item
Detecting Condition
Possible cause
DTC Strategy

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 OD SOLENOID
VALVE
• Faulty PCM/TCM
