When the dump body or OEM attachment is lowered the magnet assembly will pass in front of the body or OEM attachment down or up switch and a signal will be sent to the EPTC II. This signal indicates that the dump body or OEM attachment is DOWN.The body or OEM attachment down or up switch is used to limit the top gear while the dump body or OEM attachment is up. The EPTC II comes from the factory with the top gear value that is set to FIRST gear. The transmission will not shift past FIRST gear until the dump body or OEM attachment is down. The top gear value is programmable by utilizing the Electronic Control Analyzer Programmer (ECAP) or the Electronic Technician (ET). The top gear value can be changed to SECOND gear, THIRD gear, or FOURTH gear.The signal from the body or OEM attachment down or up switch is used to provide warnings to the operator when the truck is moving with the dump body or OEM attachment UP.
