The ECM provides ground to one side of the coil of the main relay and the other side is connected to the battery. The ECM monitors battery voltage and the voltage after the main relay.
ECM sets DTC P0562 if the ECM detects system voltage lower than the possible range of battery voltage.
Item | Detecting Condition | Possible Cause |
DTC Strategy | ● Electrical check | ● Contact resistance in connectors ● Faulty charging system |
Enable Conditions | ● No relevant failure ● Vehicle speed > 10kph(6mph) | |
Threshold Value | ● Voltage after main relay when ON < 10V | |
Diagnostic Time | ● 30 sec. | |
MIL On Condition | ● 2 Driving Cycles |
