When is the code detected?

The Engine Control Module (ECM) has detected that the electrical system voltage level is out of range.

Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Slow engine start
  • Low battery power

P0562 Meaning

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.
