C1607

C1607 EEPROM

Description
EEPROM is a nonvolatile memory that allows electrical writing and erasing of data to be stored. EEPROM is built into the EPS control unit.

Diagnosis information, sensor calibration data, temperature calibration data, etc. are stored in EEPROM.

DTC CONFIRMATION PROCEDURE

1. ERASE DTC MEMORY

With CONSULT-III
1. Record DTC.
2. Erase DTC once.

NOTE: After erasing DTC record, currently occurred DTC can be detected by reading out DTC again.

>> GO TO 2.

2. PERFORM DTC CONFIRMATION

With CONSULT-III
1. Turn the ignition switch ON (READY).
2. Steer 360° leftward and rightward slowly.
3. Return the steering wheel to the straight-ahead position.
4. Perform the self-diagnosis.
Is DTC "C1607" detected?
YES >> Proceed to STC-23, "Diagnosis Procedure".
NO >> INSPECTION END

Diagnosis Procedure

1. PERFORM SELF-DIAGNOSIS AGAIN

With CONSULT-III
Perform "DTC CONFIRMATION PROCEDURE" (self-diagnosis) again. Refer to STC-23, "DTC Logic".
Which DTC is detected?
C1607 >> Replace EPS control unit.
Except C1607 >> Check the malfunctioning system.
No DTC >> INSPECTION END

Special Repair Requirement

1. INITIALIZE EPS MOTOR ANGLE SENSOR AND CALIBRATE TORQUE SENSOR AGAIN
Always perform EPS motor angle sensor initialization and torque sensor calibration after replacing EPS control unit or steering gear assembly. Refer to STC-5, "EPS MOTOR ANGLE SENSOR INITIALIZATION AND TORQUE SENSOR CALIBRATION: Special Repair Requirement". EPS Motor Angle Sensor Initialization and Torque Sensor Calibration
