HFM-SFI (S320)

NOTE: Only S320 is equipped with On-Board Diagnostics II (OBD-II).

The HFM-SFI system is equipped with a self-diagnostic capability for trouble shooting. Vehicles are tested reading stored Diagnostic Trouble Codes (DTCs). Diagnostic modules are now referred to as diagnostic module (OBD-II). Diagnostic information can be retrieved using a generic scan tool or Hand-Held Tester (HHT) (965 589 00 01 00) and Multiplexer Cable (965 589 00 40 00). Control module will permit testing approximately 10 seconds after engine starting procedure is completed.
