That means if your car didn’t cool down below a certain threshold from your last trip, then it won’t do a check. To get the OBD2 drive cycle to begin, you must start with a cold start. It is actually about the conditions that the car is driven in that triggers the monitors. So, how do you get the car to run the readiness monitors if it is in the “not ready” mode?

If you went to the testing place and they connected their scanner and told you that you failed because the computer hasn’t reset, then that might be why you are here now wondering how far you have to drive your vehicle to get the computer to scan all the systems.
