DTC P0602 EEPROM-PROGRAMING ERROR
GENERAL DESCRIPTION
E16ACCF3
ECM is activated by power supply. Signals from several sensors, such as CKPS and APS, is inputted to ECM. Comparing
inputted signals with control LOGIC saved at micro controller and EEPROM, ECM controlls engine as actuating injectors,
solenoids and relays. To guarantee accurate control, ECM performs SELF TEST, DIAGNOSIS of several sensors and
actuators. And if serious trouble which affects vehicle performance occurrs, ECM sets DTCs.At certain cases, ECM shuts
down whole systems in order to prevent dangerous situation due to incorrect control.
DTC DESCRIPTION
EF088B88
P0602 is set when data writing on EEPROM inside of ECM is impossible.This code is due to the failure of ECM(ECM
hardware failure).
DTC DETECTING CONDITION

1.
ECM Component Inspection
1)
IG KEY "OFF", ENGINE "OFF".
2)
Disconnect ECM.
3)
Replace ECM, check if abnormal operations disappear.
4)
If problems are corrected, replace ECM.
NOTE
Input injector IQA data(7 letters) using scantool at replacing ECM.
For immobilizer applied vehicle, input pin code.

VERIFICATION OF VEHICLE REPAIR
E2C1C9FF
After a repair, it is essential to verify that the fault is corrected.
1.
After connecting Scantool select "DIAGNOSTIC TROUBLE CODES(DTCs)" mode.
2.
Clear recorded DTC using Scantool.
3.
Drive the vehicle within DTC "Enable conditions" in "General information".
4.
After selecting "DIAGNOSTIC TROUBLE CODES(DTCs)" mode and check if DTC is recorded again.
5.
Are any DTCs recorded ?
YES
▶
Go to the DTC guide of recorded NO. in Scantool.
NO
▶
System operates within specification.

DTC DESCRIPTION
EA4B51C2
P0605 is set when 1)communication error between micro controller inside of ECM and EEP ROM is detected or 2)a
different vesion of ECM is installed.
DTC DETECTING CONDITION
E63BFEFD
Item
Detecting Condition
Possible Cause
DTC Strategy
• EEPROM monitorting

• Engine running
Threshold Value
• (EEPROM communication error): communication
failure between micro controller inside of
ECM and EEPROM
• Each data range is activated abnormally.
• self test about optional devices(A/C, immobilizer,
cruise control)
Diagnostic Time
• Immediately
