2004 Nissan Altima SL only ev flashing icon. the car jerks a little when I'm at a full stop and then I accelerate.
OBDII scanners communicate with the Engine Control Module (ECM) to verify all the systems are ready to test. The system initial or name will flash to indicate that the system is not ready, and the smog test will fail or not be complete.
