Volvo All Engines (2010 Emissions) Fault Code: SPN 245 FMI 9 PID: Total Vehicle Distance
The J1587 serial data line is used as the standard communication link for on-board vehicle instrumentation, off-board service diagnostics and fleet management.
The signal is used to present the total vehicle distance in the cluster to the driver. The VECU (Vehicle Electronic Control Unit) is linked to the Engine Control Module (ECM) via this data line. The ECM uses this signal to calculate the difference between the internal ECM estimated value and the distance information from the VECU. The ECM can also use the signal in some of its function instead of the internal distance information.
Conditions for diagnostic trouble code (DTC):
1) Signal unavailable or not regularly updated
Probable cause
1) Vehicle Control Unit (VECU)
2) Tachograph
