Check all diagnostic functions as follows.
To complete a TRIP as fast as possible follow a special driving schedule.

• If the engine control module (ECM) has been without power the engine should be started a few times before the test is carried out.
• If the car has been without power and misfire-related diagnostic trouble codes (DTCs) are being verified a flywheel adaption must be carried out before verification.
• The test should take place on a road with little traffic where it is possible to drive slowly and stop at the side of the road.
• The air conditioning (A/C) can be on when the engine is running at part load but must be switched off before the engine is idled.
• Engine coolant temperature (ECT) should not be above 25°C (68°F) when the engine is started before the test.
• Ensure that there are no diagnostic trouble codes (DTCs) stored in the system before carrying out verification. Start the engine and drive according to driving schedule.
