Features and Parameters

This feature can only be used with vehicles equipped with Cummins RoadRelay 3 or later and is enabled using the Cummins INSITE service tool. At the time of enabling, six user selected pass-codes, all of equal priority and capable of locking or unlocking the engine, are also entered. The installed RoadRelay is also used to select modes of operation. There are three modes of operation:

  • Automatic
  • Semi-automatic
  • Manual

Anti-Theft Automatic Mode
In the automatic mode, the engine is always locked by the ECM at each engine shutdown. A pass-code is required to restart the engine. The feature will not lock automatically if the engine stopped because of an unintended stall or following an Engine-Protection initiated engine shut-down, unless the key-switch has been turned to OFF.

Ant-Theft Semi-Automatic Mode
In the semi-automatic mode, the driver is prompted before shutting down as to whether the Anti-Theft should be activated or not. If Anti-Theft activation is desired, all that is required of the operator is to press the ENTER key. If not specifically selected, the feature will not activate and the ECM will not lock the engine.

Anti-Theft Manual Mode
In the manual mode, Anti-Theft will only be activated if the operator enters one of the pre-programmed pass-codes. If a valid pass-code is not entered, the ECM will not lock the engine.

VSS Anti Tamper Sensitivity
Indicates the sensitivity of the VSS Anti Tamper feature. High sensitivity will have the highest likelihood of detecting tampering. Vehicles that operate primarily in urban environments should have the sensitivity set to Low.

VSS Tamper Detection
The Vehicle Speed Sensor (VSS) Anti-Tampering feature provides two functions. First, the feature activates fault code 241, if a failed sensor, a failed harness, or an intentionally disconnected sensor is detected. When vehicle parameters such as clutch switch, brake switch, accelerator pedal position, or percent load indicate that the vehicle is in motion but there is no vehicle speed input signal to the ECM, the fault code is logged. An engine speed derate also occurs if the fault is logged. Second, VSS Anti-Tampering logs fault code 242, whenever the ECM detects an attempt to tamper with the vehicle speed signal. An engine speed derate also occurs if this fault is logged, and the following message is displayed: 'Invalid or inappropriate vehicle speed signal detected. Signal indicates an intermittent connection or vehicle speed sensor tampering.'

Maximum Engine Speed Without VSS
This parameter represents maximum allowable engine speed when vehicle speed is below a threshold value.
