Drive Cycle (OBD Drive Cycle)
A drive cycle is a set of driving conditions that lets the control unit run all its emissions self-tests.
What is Drive Cycle (OBD Drive Cycle)?
It is needed after codes are cleared or the battery disconnected. It includes cold start, idle, steady cruising and deceleration. Exact conditions vary by manufacturer. Some workshops drive a planned route to complete the cycle before an inspection. The service information or a scan tool shows which monitors are still incomplete.
How it works
Each monitor runs when its conditions are met.
Why it matters for your car
Readiness monitors may stay incomplete for some days. Some tests are not completed on short trips.
