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
P0607 is set when error is detected or performance is impossible during ECM’s Watchdog related operation or concluding process. This code is due to ECM internal error.(the failure of hardware inside of ECM)
? Watchdog
The function which monitors controlling time of function inside of ECM(monitoring if booting or turning off duration is within normal period.)
DTC Detecting Condition
Item | Detecting Condition | Possible Cause |
Threshold Value | ? Watchdog system(inside of ECM) error occurs | ? ECM component |
Fail Safe | | Check Lamp |
YES |
