Volvo Drive Cycle/Readiness Code
VERIFICATION OF REPAIR
General
Verification of repair is intended as an aid if you are not sure if there is a fault or if you wish to check that diagnostic functions have been carried out.
Tips:
After repair, it may be necessary to check that the fault has actually been remedied. One way to do so is to check that the control module has carried out diagnostics for the repaired function/component without the diagnostic trouble code being regenerated. If fault tracing points to an obvious fault, it is not necessary to verify the repair.
Carrying out a TRIP
If all diagnostic functions are to be carried out as quickly as possible, the vehicle should be run following the driving procedure below.
Obs! When checking certain functions/components, the driving procedure does not need to be carried out in its entirety. The section "Diagnostic functions of the driving procedure" below describes the diagnostic functions.
General guidelines
^ The test should be performed on a road with light traffic where it is possible to drive slowly and pull over to the shoulder.
Warning! The test drive must always be executed in a safe and controlled manner. Follow applicable traffic and speed regulations.
^ Engine temperature level is of decisive importance to the first elements of the driving procedure.
Tips: Check engine temperature in VIDA Vehicle communication: Parameter readout during execution.
^ Make sure there are no diagnostic trouble codes (DTCs) stored in the engine control module (ECM) before starting the test drive. Stored diagnostic trouble codes can block diagnostic functions.
^ The total test drive time should be at least 15 minutes with an engine temperature of at least 90° C in order for all diagnostic functions to be carried out.
Driving procedure:
1. Start and warm up the engine until the temperature is at least 65°C. Then run at approx. 2000 rpm for at least 5 minutes (only applies to the diagnostic function for the tank system).
2. Turn off the engine and allow it to cool to a temperature between +4°C and +40°C.
3. Ignition on for at least 2 seconds (only applies to US market MY-00).
4. Start the engine when the temperature is between +4°C and +40°C, shift the selector lever to the "D" position, accelerate with light throttle application to 60-80 km/h (max 40-50 mph), then run at low load for 5 minutes at max 60-80 km/h (max 40-50 mph).
5. Stop the car and allow the engine to idle for 30 seconds.
6. Accelerate with light throttle application and then run with steady throttle for 5 minutes at max 60-80 km/h (max 40-50 mph).
7. Stop the car again and allow the engine to idle for 30 seconds.
8. Accelerate with at least 50% throttle application and then run with steady throttle for 5 minutes at max 60-80 km/h (max 40-50 mph).
9. Stop the car again and allow the engine to idle for 1 minute.
10. Ignition off.
Diagnostic functions in the driving procedure
For each element listed in the t1Driving procedure" section above, a corresponding description of which diagnostic function/functions is being carried out in that element is found below.
The parameter name of the diagnostic function that can be read in the VIDA Vehicle communication input is indicated in parenthesis (and bold text): Readout of diagnostic operating cycle. The following parameters/diagnostic functions can be read out:
^ Misfire.
^ Tank system.
^ Catalytic converter.
^ Heated oxygen sensor.
^ Fuel system.
^ Components.
Obs! The engine control module (ECM) continually performs the Misfire diagnostic function after engine start and is not found below.
For information on which diagnostic trouble codes (DTCs) are part of each diagnostic function, see the section "Diagnostic trouble codes (DTCs) included in the diagnostic function" below.
Diagnostic functions for each element of the driving procedure
1. EVAP control activated. Completed EVAP control is a condition that must be met before leakage diagnostics can start for the tank system.
2. Condition for the start of leakage diagnostics for the tank system (Tank system ), EVAP control (Tank system), CVVT control (Components) and thermostat (Components).
3. Diagnostics for atmospheric pressure sensor (components) performed.
4. During acceleration: Leakage diagnostics for tank system (Tank system ), EVAP control (Tank system ), CVVT control and thermostat (Components) provided that points 1-2 are fulfilled.
During travel: Diagnostics for fuel control in load range (Fuel system ) and turbo control (Components).
Diagnostics are active even if points 1-2 are not fulfilled.
5. Diagnostics for fuel control at idle speed ( Fuel system ) and idle control (Components).
6. Diagnostics for fuel control in load range ( Fuel system ), catalytic converter ( Catalytic converter), heated oxygen sensors ( Heated oxygen sensor ) and thermostat (Components).
7. Diagnostics for fuel control at idle speed ( Fuel system ) and idle control (Components).
8. During acceleration: Diagnostics for turbo control and knock control (Components).
At steady throttle: Diagnostics for fuel control in load range (Fuel system), catalytic converter (Catalytic converter), heated oxygen sensors (Heated oxygen sensor).
9. Diagnostics for fuel control at idle speed ( Fuel system ) and idle control (Components).
10. Operating cycle completed.
