You can, but it's not a good idea. You risk damaging the ECM that way. The best and quickest way to reset the ECM (without a scan tool) is to: 1) Disconnect the negative battery cable. 2) Turn on the headlight switch. 3) Wait 2 minutes, and turn the headlight switch off. 4) Reconnect the negative battery cable.
Doing it this way ensures that all of the capacitors are drained. The ECM will need to "relearn" your driving habits afterwards, which may take 30-60 minutes of driving.
by touching yhe positive and negative at the same time.
It is a safety issue. The reason is that when you are using a wrench to disconnect the battery cable you can easily touch a portion of the car that is grounded. If you were disconnecting the positive + cable first and you accidently touch a metal part the vehicle you will create a massive short circuit with the fireworks involved. The wrench in your hand will become an arc welder. By disconnecting the negative - cable first there is no danger of this happening as touching a metal part of the vehicle will do nothing as you are already working with the ground. Always disconnect the ground cable first and then you can move to the positive cable without worries.
This is a safety precaution. Disconnecting the ground cable protects you from accidental shocks, accidental engine starts (by someone unaware of your presence underneath, perhaps), in airbag equipped vehicles it prevents the airbag from deploying accidentally (expensive and/or injurious). Obviously, if the repairs in question require that battery power be available, you wouldn't disconnect it, but the protection it offers is well worth the extra minute it takes to disconnect the cable. As far as why the negative instead of the positive cable is disconnected, the reason is that if you are touching the positive cable and anywhere else on the vehicle, you'll get shocked. Not so, with the negative cable. Also, the negative cable seems less prone to sparking than the positive cable. If, however, you are working on a vehicle with positive ground (uncommon in North America), the positive (ground) cable is to be disconnected
Light from a electric bulb is generated when the negative & positive prongs inside generate a spark upon touching creating light.
Negative Impacts are Abuse: S.e.x if done it or a bad choice for you, Breakup, Big Steps, Sadness, Cheating, Inappriorate Touching. Positive Impacts- Happiness, Happy Big Steps, Slow or Fast Relationship, Parties, Kissing, Hugging.
Absolutely not. You'll need to inhale the drug, and let the THC saturate in your blood for you to test positive on a drug test. Touching a bag of marijuana will not cause you to test positive.
As long as you do not have one piece of metal touching both, nothing will happen. The voltage (about 14 volts) is not high enough to shock you.
Opposites attract. when you have electricity running through you you gain a positive charge but the air has a negative charge. Therefor your hair stands up.
Touching a fuse
Nothing happens to the vehicle if you connect the negative side first.But is is safer to connect the positive side first. Reason If the negative side is already connected and you put the positive side on you take a chance of touching a part of the body or radiator with your wrench while tightening it, causing the positive side to ground out. If your negative side is not connected yet and you touch the wrench to the body while tighting the positive side nothing will happen. So installing the positive side first reduces the chance of shorting the battery out which could cause the battery to explode.
you may have a dead battery of a shorted wire or component. be sure to connect positive to positive and negative to negative. disconnect one component at a time to find short. check that the exaust manifold isn't touching the starter
No, there is not. Most code readers will allow you to reset the check engine light, but you can reset it simply by disconnecting one battery terminal and touching it to the other to discharge capacitors in the system. If this makes you nervous, just pull a battery terminal and leave it disconnected for 45 minutes or so. When you reconnect it, the computer will be reset.
Just touching it won't make you come up positive. Taking it will.
Always wash your hands before touching your computer.
Preventing the motherboard from touching the case are stand-offs.
by not touching the mouse...lol...
It gives a higher result then smoking it.
a see through paper that hides the computer screen from touching it no matter what. isn't that so cool.
