WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect Volvo Scan Tool (ST) from the VIDA unit. Use it as a stand-alone tool and connect to the car's data link connector (DLC).
Ignition on.
Wait at least 10 seconds so the control module can run diagnostics.
Read off the diagnostic trouble code (DTC) counters.
Check the values of the counters.

If the value is greater than 0 the control module interprets this as there no longer is a fault present (intermittent fault). If the counter is 0 this indicates that there is an internal fault in the control module, and the fault is still there (permanent fault).
