The cruise control status together with the vehicle speed and calculation of fuel injection are used to maintain the vehicle set speed.The J1587 and J1939 serial data lines are used as the standard communication link for on-board vehicle instrumentation, off-board service diagnostics and fleet management.The (VECU) Vehicle Electronic Control Unit is linked to the Engine Control Module (ECM) via these data lines. Conditions for diagnostic trouble code (DTC):1) Signal unavailable or not regularly updated Observable symptoms1) Cruise control does not function Probable cause1) Electronic control unit (ECU), adaptive cruise control (ACC)2) Vehicle Control Unit (VECU) Volvo All Engines (2010 Emissions)...

The system uses the J1939 data links to control functions and communicates between the vehicle electronic control unit (ECU), the engine control module (ECM), the instrument cluster module and accessory systems, depending on vehicle model and option content.The J1939 data lines consist of an expandable data bus allowing the addition of accessory control modules. The J1939 data lines are the primary data bus. Data is prioritized and then transmitted across the J1939 data lines to the appropriate control module. Conditions for diagnostic trouble code (DTC):1) Message missing on J1939 from the following electronic control unit (ECU): Instrument cluster Observable symptoms1)...
