Access the Solenoid Bank and Chassis Node
Accessing these two items will require opening the hood and removing the fairings. After the fairings are removed, the
battery box/batteries will need to be removed from the frame rail. This process will provide open access to the chassis
node, solenoid bank and all electrical connectors.
The solenoid bank and chassis node may be removed without removing the battery box, however this will not provide
access to the splice block needed for ground connection.
Get the Suspension Air Bags to Deflate When the PTO is on
Dump body applications will be able to utilize a function such that when the PTO is active (and the dump body is being
lifted), the body is sitting on the suspension bump stops. This provides a more stable platform than the airbag.
EE_PAR_EOA_bool_SuspensionDumpWithPTOActivation enables this functionality. If any switch is configured to be a
PTO switch and any switch is configured to be Suspension Dump, the Suspension Dump switch shall be considered as
active. All existing Suspension Dump interlocks must still pass for the suspension to be dumped.
