Klaus,
Do I really have to do the following to a "T" to clear these darn monitors?
Just had the aft O2 sensor replaced, so I am back to square one.
General Instructions
1. No Diagnostic Trouble Codes (DTC) should be present in the ECM or TCM.
2. Fly wheel adaptation must be completed before diagnostics can run (Refer to Driving to change the flywheel status to "Ready").
3. Connect Volvo Systems Tester (VST). Enter the DIAGNOSTIC CHECK menu to verify if a trip has been completed as shown. Please Note: If using a scan tool other than the VST, different terms for reporting the same status may be displayed. 'READY' may be displayed as 'COMPLETE' and, 'NOT READY' may be displayed as INCOMPLETE'.
4. In order to insure EVAP leakage detection completion, the fuel level in the car should be above 1/4 and below 3/4 tank.
5. Air conditioning (A/C) must be off during idle periods. A/C compressor activation during the EVAP diagnostic may interrupt the EVAP test.
6. Select a suitable route where it is possible to achieve necessary speed and load conditions and occasionally stop at the side of the road safely. This needs to be done while obeying all traffic regulations and posted speed limits.
7. Important: Keep as steady a throttle pedal as possible when driving.
8. Engine temperature at start must be between + 29°C (84°F) to + 49°C (122°F). If engine temperature is below + 29°C, start engine to warm up over + 29°and then shut off. Restart engine when coolant temperature is between + 29°C and + 49°C.
