Overview

The Endurant XD Pro Transmission incorporates enhanced controls to support various vocational features. Features include 2-Speed Axle, Auxiliary Transmission (Aux Trans), Force Neutral, Hold Neutral, Neutral Output, Power Take-Off (PTO): PTO 1 and PTO 2, Split Shaft PTO (SSPTO), Reverse Output, Rock Free Mode and Secondary Configuration Mode.

The Transmission Control Module (TCM) is equipped to receive 4 switch inputs and control 3 relay outputs that can be configured in an Input/Output (I/O) Calibration Package to support these vocational features. All external circuit inputs and outputs connect to the TCM in the 20-Way TCM Body Harness Connector.

Listed below are the Input / Output Calibration Packages and recommended wiring diagrams to assist the OEM or body builder with vocational feature integration. Once circuit and component installation is complete, ServiceRanger is required to configure the I/O Calibration Package in the TCM.

Note: Additional information can also be found in PTO installation Guide TRIG2620 and the Endurant XD Installation guide TRIG0960.

Package 37: Reset I/O Calibration to Off

This package is used to reset or turn off an I/O Calibration Package configured in the TCM. Use this procedure when:

• TCM is currently configured with an I/O Calibration Package and a new I/O Calibration Package is desired. Failure to reset TCM may result in an inoperable vocational feature and/or TCM I/O fault codes to set Active.
• TCM is currently configured with an I/O Calibration Package and no I/O Calibration Package is desired. For example: when a truck is being sold and PTO components and wiring have been removed from transmission. Use this procedure to turn off an I/O Calibration Package currently configured in the TCM. This will ensure no TCM I/O fault codes are set Active.

I/O Calibration Package Installation Process

• Identify I/O Calibration Package based on the vocational feature(s) to be installed - Reference I/O Calibration Package Index below.
• Install vocational feature components (PTO, Reverse Switch, etc.) and associated wiring - Reference I/O Calibration Package wiring diagram.
  Warning
