VOLVOUU All Engines (2004 Emissions) Fault Code: PID 228 FMI 11 Calibration Factor

Description

Fault Condition: The Calibration Factor code will set when the Engine Management System (EMS) Module has lost the Calibration Factor Signal from the Vehicle Electronic Control Unit (VECU).

Possible repairs:

1) Verify that code PID 228 is set. If code PID 228 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the VECU connectors and wires for poor connections.
2) Turn the ignition key OFF and connect a diagnostic computer. Turn the ignition key ON. Use the diagnostic computer to attempt to communicate with the Vehicle Electronic Control Unit (VECU). If communication can be made with the Vehicle Electronic Control Unit (VECU), the fault may be intermittent. Wiggle the harness and connectors to try to set the code. If fault in the harness is found, repair or replace the harness.
If there is NO communication with the Vehicle Electronic Control Unit (VECU) via the diagnostic tool, go to the Trouble Shooting Procedure for the Data Lines.
