ROPS diagnostic functions: General
ROPS = Roll Over Protection System.
The ROPS control module has an on-board diagnostic (OBD) system, the Volvo on-board diagnostic (OBD) system. This provides self diagnostic and other information which can be read off using the Volvo Scan Tool (ST) connected to the data link connector (DLC).
When the ignition is switched on (ignition position I or engine on), the ROPS on-board diagnostic (OBD) system carries out an initial self test. The ROPS on-board diagnostic (OBD) system then goes into monitoring mode, carrying out a continuous self test on the system. Continuous self diagnostic of the system. The control module checks for internal faults in all ignition cable outputs and in the output for the ROPS warning lamp in the combined instrument panel.
