Component Location
General Description
ECM is activated by power supply. Signals from several sensors, such as CKPS and APS, is inputted to ECM. Comparing inputted siganals 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
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
Item | Detecting Condition | Possible Cause |
DTC Strategy | ? EEPROM monitorting | ? Version difference between ECM and ECM communication module ? ECM component failure |
Enable Conditions | ? 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 |
Fail Safe | Fuel Cut | YES | |
EGR Off | NO |
Fuel Limit | NO |
Check Lamp | NO |
