Depends on vehicle & state. You may need to have ready monitors and there may be a minimum amout of ready monitors varying by model, year and state. There must also be no DTC's. Best way to make monitors ready is take a nice long car ride for about 20 miles and do not disconnect battery at all.
Your vehicle's OBD system collects data while you are driving and uses it later to determine if your vehicle passes the OBD emissions test. In some cases, the computer cannot collect enough data and indicates it is "not ready" to provide test results. This can occur if repair work was performed or the battery was disconnected recently. It normally takes at least a week of combined highway and city driving for the computer to complete its systems check and be "ready" for the OBD test. If a vehicle fails because of an emissions problem, it needs to be repaired and pass a re-test at the same inspection station within 60 days of the initial test. For vehicles that are "not ready," the OBD system was unable to complete its systems check for the OBD test. This is usually due to recent repairs or a recently disconnected battery. Usually, at least a week of combined highway and city driving will reset the OBD system so that it will be "ready" for the OBD test. If your vehicle is still "not ready" at the re-test, the inspector will give you a notice explaining that additional driving is required to reset system monitors. After 60 have days have passed, you will need to pay an additional fee for each subsequent OBD test.
0 once you press erase on your scanner or the shop presses it it is reset as for when the sensors get all the info they need to say ready it is usually about 3 days of my normal driving
i have been told if y try to start the vehicle anywhere from 1 to 100 times it will reboot itself if you are trying to reset for an inspection you need a computer to plug into your ecm if you un-hook the battery it will only show up at the inspection station
all we need is the model of the system.
50 to 100 miles
A computer should not have an ignition system.
Unplug the battery for 15 mins will reset the check engine light, but watch will reset all your sensors to. Personal experience it will not read for at least 100 miles, so dont do it when you need an inspection
The system will need to be reset or repaired. To reset a original GM system start by using the remote lock and unlock the doors. Then have a repair shop scan the computer and see if it can be reset. If that does not work it will need to see a GM dealer or qualified repair person.
need to find the reset code for mss3000 alarm system
Carefully!!! You will need to pressure bleed the system and it will require a scanner to reset the light.
disconnect the negative battery cable, wait a couple hours, then reconnect. If you are trying to reset the inspection service light you will need to take it to someone or get on a board for model specific info.
Remove the battery cables for 5 minutes, should do it. Then the computer will reset and relearn after driving again. If a major fault was present before, it will return via the check engine light. If you need an inspection, then unhooking the battery for 5 minutes and driving maybe 20-40 miles and then going for inspection may do the trick. There is a small window where the check engine light hasn't come on yet and the IM monitors are mostly ready for inspection.....just before the check engine light comes on again. It will pass, in this window. But when the check engine light comes on again, it will not pass.
