When the yellow light is means that the tool finds a possible problem. It indicates the following two conditions: (1) Pending DTCs exist. Please check the I/M Readiness test result screen and use the Read Codes function to view detailed codes information.
How do you know when OBD2 is ready?
To determine if readiness OBD II monitors are complete:
- Turn the ignition key to the “on” position for 15 seconds without cranking the engine.
- If the “Service Engine Soon” light blinks eight times, one or more readiness monitors are incomplete.
How long does it take OBD monitors to be ready?
About one week of combined city and highway driving is usually enough to allow the monitors to reach complete status.
What is I’m monitor status?
The I/M Monitor Status icons are associated with INSPECTION and MAINTENANCE (I/M) READINESS STATUS. Some states require that all vehicle Monitors have run and completed their diagnostic testing before a vehicle can be tested for Emissions (Smog Check).
How do you know if your car will pass emissions?
The new test involves checking your gas cap, looking at the check-engine light and plugging a device into your car’s diagnostic link. In most cases, your car will pass unless the check-engine light is on when you pull into the test facility.
Why is my car not ready for smog check?
A “not ready” result means your vehicle’s computer has not had a chance to check all of the parts of the emissions control system for problems – so it cannot determine if everything is working as designed. Your vehicle has an emissions control system problem preventing it from self-testing.
How many miles should you drive after resetting check engine light?
Clock some miles To make sure the check engine light does not reappear, it’s recommended that you drive your car 30 to 100 miles. This enables the vehicle’s “Drive Cycle” to reset, as the various sensors need time to recalibrate.
