Battery Voltage Diagnostics

Battery Voltage Diagnostics

This feature allows a warning light to be connected to alert the vehicle operator that the vehicle battery voltage is below a certain voltage.



Wiring Tab

Connections

Output

Select an available output wire, typically a DPO (Digital Pulsed Output) or Stepper Output that will be connected for the Battery.

Active State

Controls the whether the output is normal or inverted. Low will ground the output wire when the output is set to be On. Setting to High will invert this signal, with the output wire being grounded when the output is set to be Off, and not grounded when it is set to be On. (Default = Low)

Display Tab

Warning Minimum

When the Battery Voltage reads below this amount, any battery voltage items on the ESP software will flash Red as a warning of low voltage.

Warning Maximum

When the Battery Voltage reads above this amount, any battery voltage items on the ESP software will flash Red as a warning of high voltage.

Diagnostics Tab

The settings in this tab allow limits to be set for the detection of fault conditions related to the battery voltage.

Operating Min

When enabled allows detection of battery conditions that could indicate a sudden drop in voltage. This will activate the DTC P0562. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)

Operating Max

When enabled allows detection of battery conditions that could indicate a sudden spike in voltage. This will activate the DTC P0563. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)

Battery Light Tab

On Value

If the battery voltage falls below this voltage the battery light will turn on.
