Trip Driving Cycle Using VOLVO System Tester (VST)

NOTE: The following information is from Volvo technical service bulletin No. 0059, Section 2, Group 23, dated July, 2002.

NOTE: Engine idle and drive times may be slightly longer than given time, but must be NO LESS than set amount.

Connect VST and start engine. Test drive vehicle at engine speed of 1500-2000 RPM. Maintain engine RPM for 6 minutes.
Stop vehicle and idle engine for 70 seconds. This allows ECM to check fuel trim adaptive functions.
Test drive vehicle at engine speed of 1600-2000 RPM. Maintain engine RPM for 6 minutes.
Stop vehicle and idle engine for 70 seconds. This allows ECM to check Secondary Air diagnosis functions.
Test drive vehicle and reach at least 45 mph. Drive for 5 minutes with engine at 1800-2200 RPM.
Stop vehicle and idle engine for 60 seconds. This allows ECM to check EVAP leakage diagnosis functions.
Test drive vehicle and reach at least 45 mph. Drive for 4 minutes with engine speed of 1800-2200 RPM.
Stop vehicle and idle engine for 60 seconds.
NOTE: In order to set cycle flag for idle air diagnosis, engine must come to idle 7 times. Step 9 ensures this.
Test drive vehicle at engine speed of 1800-2200 RPM. Stop vehicle and idle engine for 60 seconds. Repeat this step 3-4 times. This allows ECM to complete diagnosis of all systems. DO NOT shut engine off.
NOTE: DO NOT shut off engine or entire TRIP cycle will have to be repeated.
With engine still running, move gear selector to neutral position and apply parking brake. Ensure all diagnostics are complete using VST. Access DIAGNOSTIC CHECK menu. It will display TRIP COMPLETED if TRIP was successful. If 2 TRIP cycles have been completed, VST will also display READINESS=YES or NO. If not all diagnostic functions are complete, parts of TRIP cycle can be redone. If this is the case, see RE-TESTING PARTS OF TRIP CYCLE USING VOLVO SYSTEM TESTER (VST) .
