The system voltage has to be high enough to guarantee in order to perform diagnosis functions. The ECM monitors battery voltage..
The ECM sets DTC P0563 if the ECM detects system voltage higher than the possible range of battery voltage.
Item | Detecting Condition | Possible cause |
Monitoring Strategy | ● Signal check, high | ● Over charge in generator ● Faulty ECM ● Bad connection in generator |
Threshold value | ● Battery Voltage > 17V | |
Enable Conditions | ● Vehicle speed : > 25Km/h ● Time elapse after start : > 120s | |
Diagnostic Time | ||
MIL on condition | ● > 0 . 2 sec |
Engine stop : 11 ~ 13V
Idle : 12 ~ 15V
