The Engine Control Module(ECM) detects the following conditions:
- The ECM is unsuccessful in receiving a message from a J1939 source.
- The ECM is not receiving a valid message from a J1939 source
The power train data link is designed to offer electronically controlled Anti-Lock Brakes (ABS),traction control systems,and/or transmission controls. This is accomplished by a momentary reduction of engine rpm and/or engine torque, that is triggered by a signal from an off-engine control module for the ABS, the traction control, or the transmission. An off-engine control module is a control module that is not part of theCaterpillar engine control system.
