P0562
DTC P0562
Circuit Description
The powertrain control module (PCM) monitors the system voltage to make sure that the voltage stays within the proper range. If the PCM detects an excessively low system voltage, DTC P0562 will set.
When the charging system detects a fault, the instrument panel cluster (IPC) displays a message or the charge indicator will light.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC P0562 System Voltage Low
Conditions for Running the DTC
* Engine run time is more than 20 seconds and above 1,200 RPM.
* Vehicle speed is above 8 km/h (5 mph).
Conditions for Setting the DTC
The PCM detects an improper voltage below 11 volts for 5 seconds.
Action Taken When the DTC Sets
* The PCM stores the DTC information into memory when the diagnostic runs and fails.
* The PCM will store conditions which were present when the DTC set as Failure Records data only.
* The PCM disables most outputs.
* The transmission defaults to a predetermined gear.
* The torque converter clutch (TCC) operation is inhibited.
* The IPC displays a message.
* The malfunction indicator lamp (MIL) will not illuminate.
Conditions for Clearing the DTC
* The Conditions for Setting the DTC are no longer present.
* A history DTC will clear after 40 malfunction-free ignition cycles.
* The PCM receives the clear code command from the scan tool.
