How long do I have to drive my car to reset the computer?
So why is the light still on? Here’s something you probably don’t know: after clearing the car’s computer you will need to drive for about 50 to 100 miles. As you drive your car the computer will monitor all the sensors and register the results.
How long is a drive cycle on a car?
Preparation for it will take eight hours but, all in all, a basic drive cycle test should take around 30 minutes to complete, with about 20 minutes of actual driving.
How many drive cycles does it take to turn off a mil?
The PCM can perform this test once during the drive cycle. As I discussed earlier, most emissions-related DTCs take at least two drive cycles to set, so it stands to reason it will take at least two passes to turn off the MIL. Keep in mind the second drive cycle will not be complete until you turn off the ignition.
Do I need to reset car after changing battery?
Yes. You will need to reset your settings. Usually the dealer can do it free of charge but no promises. If you take a battery off and put a new one on, if there was anything hooked up the the battery, i.e. the hose you are speaking of, reinstall it.
How long does battery need to be disconnected to reset ECU?
Disconnecting the battery for a short time may not do the trick because the car’s computer, or ECU, still has some current in it. Waiting for over 15 minutes after disconnecting the engine will help ensure the equipment is reset.
What is a Drive Cycle for emissions?
a drive cycle is one of the methods used by a vehicle’s powertrain control module (pcm) to determine whether an emissions system repair was performed successfully. it involves a special test drive that duplicates the scenario of a person starting the car and making a short freeway trip, as if driving to work.
How do you do a Drive Cycle for inspection?
General Motors Drive Cycle For Smog Check
- Start the vehicle from a cold start.
- Let the engine run on idle.
- Accelerate to 55 mph.
- Hold a steady speed of 55 mph for 3 minutes.
- Let go of the accelerator and coast until the vehicle hits 20mph.
- Accelerate again until 60 mph.
- Hold steady for 5 minutes at 60mph for 5 minutes.
How do you know when obd2 is ready?
To check if your vehicle’s OBD II system is ready, you must do the following:
- Turn the ignition switch to the “ON” position, but do not crank or start the engine.
- As soon as you turn the ignition switch to the ON position, you will see the MIL (Check Engine Light) symbol come on as part of a normal bulb check.
How do I get rid of permanent OBD code?
The only way to clear a PDTC is to fix the underlying problem with the vehicle that originally caused the PDTC and its corresponding DTC to set, and then allow the vehicle sufficient drive time to re-run the monitor that identified the problem in the first place.
Can I pass emissions with EVAP not ready?
Answer: Your vehicle may pass the smog inspection with an incomplete EVAP monitor.
How do you complete a Drive Cycle on a Nissan?
Begin driving. Accelerate smoothly to 56 mph with the transmission in Drive (standard power mode and transmission in auto mode) then release gas pedal and coast for 10 seconds. D. Accelerate again to 56 mph and maintain speed for at least 10 minutes.
How many drive cycles does it take to clear a permanent code?
You’ll need to complete three of these cycles (from cold start if applicable) to successfully clear the code. After the monitor runs three times with no problems the code will clear and you’ll be happy (confirm this, though).
What is the difference between a trip and a warm up cycle?
A drive cycle or trip, by the way, is not just an ignition cycle, but a warm-up cycle. It is defined as starting the engine and driving the vehicle long enough to raise the coolant temperature at least 40 degrees F (if the startup temperature is less than 160 degrees F).
