Disconnecting or replacing a battery on a computer-equipped vehicle may cause starting, driveability and a number of other problems, including loss of air conditioning, power accessory functions (door windows, seats, sunroof), false warning lights, even damage to certain electronic modules! One of the things I wanted to do with the article was list all of the vehicle applications that have known battery disconnect issues. On vehicles with known battery disconnect issues, there should be a big red warning label on or near the battery to warn people. Warning: Disconnecting the battery to reset the PCM on a growing number of late model (2003 and newer) vehicles can do more than erase the Keep Alive memory. Also Note: Disconnecting the battery will NOT allow a vehicle to pass an OBD II plug-in emissions test. Erasing the PCM's adaptive memory may also affect the way the transmission shifts and feels.
It resets the FMEM (Failure Mode Effects Management) module on certain late model Ford vehicles.
It resets the ABS (Antilock Brake System) and SIR (Supplemental Inflation Restraint) or airbag modules. Chevy Tahoe Loss of voltage to the vehicle electrical system causes the 4WD module to go to sleep permanently. Toyota (various models) If the battery is disconnected while the key is on, it can set a fault code for the airbag system and turn on the airbag warning light (which deactivates the airbag system until the fault is cleared with a scan tool). Subaru (various models) Disconnecting the battery can trigger the anti-theft system, preventing the vehicle from starting when the battery is reconnected. Honda (various models) Disconnecting the battery will set a code and turn on the air bag light (which also disables the airbag system). WARNING: Regardless of the year, make or model of vehicle NEVER disconnect the battery while the engine is running or the ignition key is on. If a battery has to be disconnected prior to doing electrical work on a vehicle (which is highly recommended to prevent an accidental short that might damage wiring or modules), or if an old or weak battery is being replaced, voltage MUST be maintained to the PCM and other modules while the battery is disconnected. Voltage to the PCM and other modules can be provided by connecting a 12v backup power supply to the battery cables, using jumpers to attach another 12v battery to the battery cables, or plugging a small 9 volt battery Keep Alive Memory (KAM) saver into the cigarette lighter or a 12v power receptacle.
The Schumacher OBD Memory Saver Cable is another handy device for preserving learned data, stored codes and programmed electronic settings such as clocks, radios, seat positions, keyless entry systems, alarms and more. The Keep Alive Memory chips in most modules require very little current to retain their settings, anywhere from a few milliamps up to 10 to 15 milliamps depending on the module. Many modules have internal timers that either turn off the module to put it into a "sleep mode," or power down the module to a "standby mode" to reduce the parasitic power drain after a predetermined length of time when the key is turned off or the vehicle's occupants leave the car.
As a rule, the parasitic drain on most late model vehicles should be less than 50 milliamps one hour after the vehicle has been shut off and left undisturbed.
Keep in mind, though, that opening a door, the trunk or turning anything on can wake up various modules and start the timer countdown all over again.
If replacing a battery (new or used), make sure the battery is FULLY CHARGED before installing it.
Connect the POSITIVE (+) battery cable first (which may be color coded RED), then the NEGATIVE (-) GROUND cable last (which may be color coded BLACK). Throughout the rest of this website you'll find in-depth articles describing in intricate detail how everything automotive works. If you're looking for TSB (Technical Service Bulletins) or wiring diagrams for your vehicle, BBB industries have access to most of them for free.
While lurking on the Internet and collect the best tips for you, I tried to find the best online-resource with different wheels and tires. This is something everyone can do - it's quick and easy and it'll tell you if your engine needs oil.
Only choose superior car detailing supplies to keep your car's interior and exterior like new.
If you're going to do any work on your car involving the electrical system, disconnect the battery first.
When you indicate one way and the blinker flashes quicker than when you indicate the other way, it means one of the bulbs has blown.
Most headlight bulbs now are filled with halogen and have special coatings on the outside of the glass. The electrical fault light.This warning light is different in every car but normally it looks like a picture of a battery, similar to the picture on the left here. Brake warning light 2If you've got an ABS-equipped car, you also have a second light - the ABS light.

It can also erase vital learned information that is absolutely necessary for other modules to function normally.
For example I rarely travel at the speed limit and if the other three roads are patently free of traffic, I'll coast through a 4-way stop.
On this page, I've simplified all that knowledge into a series of basic car maintenance tips, subdivided by category.
If you leave it too long, the combination of road grime, moisture and heat from your brakes will bake it on to your wheels.
Most tyres come with tread wear bars built into them now - find one, examine it and if your tread is too low, replace your tyres.


Rubber perishes, more so in extreme conditions like those found in an operating engine bay. The page you're reading is free, but if you like what you see and feel you've learned something, a small donation to help pay down my car loan would be appreciated. Sportier cars have higher compression engines which generate more power and require higher octane fuel to prevent detonation. There are plenty of decent quality waxes and polishes on the market today and if the last time you waxed or polished your car was over a decade ago, things have changed considerably since then. They don't damage the paint and are easy to move around and ultimately remove when the fad has passed. If your battery terminals or contacts aren't clean, you're making it more difficult for the current to pass around the electrical system. An auto parts store will be able to tell you what sort of bulb you need to replace it with and your manual should show you how to get at the indicator bulbs - they're different on every car. If you pick the bulb up by the glass with your fingers, you will leave trace amounts of oil and grease on the glass. This is a fault-registering system connected to sensors all over the car, engine, fuel and emissions system.
If tightening the gas cap didn't do it, you'll need to find someone with an OBD2 diagnostics tool or reader.
You'll see it come on and go off when you start your engine as part of the car's self-test, but if this light comes on and stays on, it means the electrical charging system is no longer working properly. If this comes on it means that the level of coolant in your radiator is low and needs topping up.
Low oil pressure is serious and if you continue to drive with this light on, eventually your engine will die. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.

Main product include automotive parts, lead-acid battery parts, air power tool, garden tools. This means that (a)I'm honest and (b)I'm like 90% of other drivers even if they claim they never break any laws. These tips apply to pretty much every car owner, from business fleet owners, to specialists like a limo service, to the weekend hobbyist. Brake dust normally clings to wheels with static electricity so a damp sponge and clean cold water is the best way to get it off. Get your timing belt and accessory drive belt checked every 25,000 miles, preferably replacing it every 50,000 miles.
To check the oil, park on level ground and wait until the engine has cooled down after driving, then locate the dipstick. Every engine is different but if you check your handbook you should find where the coolant reservoir is. The wax and polish compounds are far more sophisticated both in terms of protection from fading, the look of the finish, and the ease of application. If you leave it in the sun and the poop bakes on, you could end up with a dull spot in the paint. Remove the terminal caps as described above and clean each contact post with a wire brush to get a nice clean metal contact surface.
When the bulb is used, that area of the glass will get hotter than the rest and it will eventually cause the bulb to crack. P0440 is the code for Evaporative Emission Control System Malfunction which covers a multitude of sins.
On some cars it's as simple as counting miles before it comes on, whilst on others it maps engine temperatures, oil temperatures, air temperatures and other indicators of probable stress to tell you when it might be time for new oil or a service.
Low oil pressure can be caused by a failed oil pump, a blocked oil filter or strainer in the sump, or by low oil levels - for example if your engine is burning oil. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
Import charges previously quoted are subject to change if you increase you maximum bid amount. Our company has first-class production equipment, strong R&D capabilities in integrated.
Major recalls normally result in owners being contacted, but minor ones get done each time a vehicle is taken to a main network dealer. Pull it out and wipe it clean, then push it all the way back in until the top of it is seated properly in the dip tube again. It will normally be bolted to one side of the engine bay or the other, and be a white semi-transparent bottle. If you need to take the battery out, you can now take off the positive connector.Why negative then positive?
If the cellphone is plugged into the charger, you can use it indefinitely, but when you disconnect it from the charger, there's a limited amount of time before your battery runs out.
The brake warning light doesn't have a standard meaning; it could be used for multiple purposes.
It could be something as simple as dirt in one of the sensors, or something as costly as an entire ABS unit replacement. The coolant system is pressurised and it could easily release pressure and spray you with boiling coolant. Speed isn't killing me or slaughtering the women, children and babies of every driver near me (like everyone nowadays seems to think it will). There are simple things that you can do on your own like being able to -->use a silicone lubricant to protect your car from rusting. TSBs are the bulletins sent to the dealer networks containing info on known bugs and issues with all makes and models that need to be rectified when the vehicles come in. Wait until your engine is cool and take a look at it - the outside should have 'low' and 'high' markings on it and the level of coolant inside should be between the two.Do not take the radiator cap off to check coolant levels. If you disconnect the positive side of the battery first, the negative side is still connected to the entire car.


Handheld OBD2 diagnostic tools can be plugged in to the OBD2 port which is normally under the dash on the driver's side. For example, the same light may be used to show that the hand brake (parking brake for the Americans amongst you) is on.
Low oil pressure is A Bad Thing and your engine won't thank you for leaving this problem untreated. Some tips have simple explanations right here whilst others link back to the articles in the rest of the site. If you're looking for a particular TSB or wiring diagram for your vehicle; TSBs and wiring diagrams. If the coolant system is still hot then it is still under pressure and the pressure release will burn you. Partly, yes, but if you park under a tree where birds help repaint your car with recycled blueberries, that guck will come off a lot easier if it falls on a waxed paint job. If you drop a tool and it lands on the positive battery terminal and touches anything else on the car, you'll have an electrical short. If you've filled up with petrol and not twisted the gas cap until it clicks, you've not sealed the fuel system. Better to find a garage or mechanic that will read the code and actually give you a diagnosis rather than just making you pay to find out a number. If you take your car for a service, the garage should reset it for you.Typically this light will come on when you start your car, and then turn off again as part of the self-check. Every car has an alternator - the charger - and a 12v battery used to supply power to the electrical system. If that's the case and you're driving, you ought to have noticed the smell of burning brake dust by now.
It's important to note that this light normally comes on when you start the car and then switches off a few seconds later.
Top up the system with either a pre-mixed coolant bought from a shop, or with distilled water.
For example when you turn out of a side street on to a main road, you should turn into the inside lane. If you can't find what you're looking for, try the search button at the end of the top menu.
Smaller garages and local mechanics will normally do this for you for a small fee, and being independent, the diagnosis won't be predicated on you buying some expensive parts from a corporate chain.If you're a do-it-yourself type used to working from shop manuals, then a lot of places that will give you the diagnostic code for free.
If it stays on for 10 seconds then turns off, it normally means you're within 500 miles of needing a service. If the alternator becomes faulty or the drive belt to it snaps, then it will not be able to do its job. If it blinks, throbs, flashes or in any other way draws your attention to itself, then take note. Don't use tap water - the mineral deposits in it boil out in the cooling system and calcium gets depositted around the inside of the radiator making it less efficient (which will eventually cause it to fail).
Not swing across into the outside lane, because that's where people will tend to be driving who will be assuming (mostly wrongly) that you're going to use the inside lane.The same is true for turning across large intersections. If you still can't find what you're looking for, or have a suggestion for something else I should cover, contact me using the contact button on the top menu bar.
Now, if a tool drops on to either of the battery terminals, it doesn't matter if it touches part of the chassis or not - there's no continuous path for the electrical current.Reconnecting your battery. The historical codes are lists of things that have been detected in the past but are no longer an issue, whilst the active codes are things that are a problem right now. In fact, on a lot of cars, that code is so common they'll actually have some way of telling you to check the gas cap. In America specifically, the Schuck's chain do free diagnostics checks (Checker, Kragen, Murray's, Advance) as well as AutoZone. If it flashes for 10 seconds, it normally means you've exceeded a recommended service interval. The longer you drive, the more your car will use up the remaining juice in the battery and eventually the engine will die.
It's always best to use pre-mixed coolant, or to mix your own rather than using neat water. This diagram shows where the cars should go (in green) and where they seem to go all the time (in red):Please, people - don't change lanes in intersections. Connect the positive terminal first, and the negative second - the reverse of removal, and for the same reasons. Codes are subdivided into B-codes (body), C-codes (chassis) and the biggest list of all - P-codes (powertrain). In the Honda Element, for example, if a P0440 code is logged, the dash scrolls "CHECK GAS CAP" across the odometer display. Compared to a steady light, a blinking ABS light normally indicates something more serious. The coolant mixture behaves as an antifreeze in winter as well as a corrosion-inhibitor to stop your engine rusting from the inside out. When you slip the negative connector on, there will be a spark as it gets close and makes contact with the negative battery terminal.
Because it would be such a drag if the same indicator meant the same thing in every vehicle.
Might I suggest crossing double yellow lines on long, straight mountain roads when the person in front is doing 30 below the speed limit?
The first time you pull the dipstick out, it will have oil all over it and it will be difficult to tell where the level is.
Note : even if the light does go off, the code will likely still be stored in the OBD system and will show up next time it is checked. That's why you need to wipe it on a rag to get a clean dipstick, then dip it back into the oil to get a good reading. The bigger problem in this situation is who the hell decided double yellow lines were needed in the first place.
The alternative, if you're into maintaining your own vehicles, is to buy a reader and do it yourself.
