P0562 DODGE - System Under Voltage
- Battery defective
- Loose or missing alternator drive belt
- Faulty alternator
- Open or short system voltage circuit
- Slow engine start
- Low battery power
The battery supplies electricity to the Engine Control Module (ECM) even when the ignition switch is OFF. This electricity allows the ECM to store data such as Diagnostic Trouble Code (DTC) history, freeze frame data, fuel trim values and other data. If the battery voltage falls below a minimum level, the ECM will conclude that there is a fault in the power supply circuit. The next time the engine starts, the ECM will turn on the Malfunction Indicator Light (MIL) and a DTC will be set.
