VERIFICATION OF VEHICLE REPAIR

E7D3C8AE

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 P0606 ECM/PCM PROCESSOR(ECM-SELF TEST FAILED)

GENERAL DESCRIPTION

E9A500E2

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

E9272743

P0606 is set when 1) writing/reading error inside of ECM occurs. 2) error of APS 2 ground checking which is repeated
every 0.2 sec. or 3) the voltage of sensor power supply 1 and 2 ( the standard voltage of A/D converter) are below 4.7V
or above 5.1V. This code is due to ECM internal failure.

SIGNAL WAVEFORM AND DATA

E245EC4A

Fig.1

Fig.2

Fig.1)  Ground checking signal of APS 2 signal is for ECM to monitor APS 2. This signal drops APS 2 output voltage to below
           200.39mV every 200msec. If APS 2 output voltage does not drop  to below 200.39mV, ECM sets DTC as recognizing 
           ground circuit error of APS 2

 The waveform below 200.39mV is not detectable in ground checking signal waveform of APS 2 signal. Instead, the waveform

     which drops a little is detected. If APS 2 data of "SERVICE DATA" on the Scantool varies from 350mV to 0mV periodically, 
     it means it works normally.
Fig.2) APS 1 and APS 2 signals are measured simultaneously, Check if 5V sensor voltage(the standard voltage of A/D converter
          inside of ECM) is from 4.8V to 5.16V.

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.
