For an example of screen display during testing, see Fig 1 .

Connect Volvo System Tester (VST) and read out fault memory. See RETRIEVING & ERASING DTCs . Diagnose all DTCs before proceeding with system readiness check.
Enter DIAGNOSTIC CHECK menu to verify that a TRIP cycle has been completed. If TRIP cycle has not been completed, see TRIP DRIVING CYCLE USING VOLVO SYSTEM TESTER (VST) under DRIVE CYCLES. If TRIP cycle is complete, go to next step.
Check flywheel adaptation status. If status is NOT READY, see SETTING FLYWHEEL ADAPTATION USING VOLVO SYSTEM TESTER under PROGRAMMING. If status is READY, go to next step.
NOTE: Ensure A/C is off during engine idling while testing. Compressor engagement will interrupt EVAP test.
Check vehicle fuel level. Tank should be 1/4 to 3/4 full for accurate EVAP leakage detection completion. Adjust fuel level as necessary.
Engine temperature must be between 84-122°F (29-49°C). If engine is above 122°F, shut engine off and allow it to cool down to within range.

NOTE: Move ignition key from position 2 directly to position 3 (engine start). DO NOT cycle ignition key.

Move ignition key to position 2. Engine off. Access diagnostic check menu on scan tool and go to DTC 112. Start engine. Status of DTC 112 should change from NOT TESTED to TESTED. If status change happens, system readiness check is complete.
