On Board Diagnostics For Rancho Cucamonga Motorists

Some Rancho Cucamonga drivers wonder why Haven Mobil and other Rancho Cucamonga auto repair shops charge a fee for diagnostic services.

Think about it: When you hire a local Rancho Cucamonga HVAC technician to check out a problem with your air conditioner you’ll probably pay a diagnostic fee. When you visit your Ontario doctor for a health problem, you pay the physician to diagnose the ailment and of course for the tests that go along with it.

On Board Diagnostics For Rancho Cucamonga Motorists

So receiving a diagnostic charge at Haven Mobil for a tricky automotive problem shouldn’t be a surprise. In the Rancho Cucamonga area, automotive diagnostics can cover quite a range. If you hear a noise in your sedan brakes when you slow down in rush-hour traffic on a busy California highway, you pull off the next off-ramp and take a quick visual check. That is usually enough to know what needs to be done. If you’re having an intermittent problem with your sedan engine, however, Haven Mobil diagnosis may be much more involved.

Much of the Rancho Cucamonga drivers’s confusion comes when the problem involves the check engine light. The check engine light comes on when the engine management computer has sensed a problem.

There’s a common misconception among Ontario, Alta Loma, and Claremont drivers that the trouble code tells the Haven Mobil technician exactly what’s wrong. They wonder why there is a diagnostic charge – because the scanner quickly gave the diagnosis.

In reality, it is not that easy and straightforward. The computer monitors many sensors throughout the vehicle. When one of these sensors has a reading that’s out of parameters, the computer will record a trouble code and turn on the check engine light.

The sedan computer’s trouble code just tells the Haven Mobil technician what engine parameter is out of range – not what’s causing it. The technician needs to determine the underlying problem that’s causing the malfunction.

There are many problems that could cause a troublesome sensor reading for Haven Mobil customers. The Haven Mobil service advisor makes a list of the most likely causes and begins tracking down the source of the problem. This takes time.

Rancho Cucamonga service centers subscribe to databases that document possible causes for all the possible trouble codes. The databases outline procedures for confirming a diagnosis and provide the documented repair. These databases are specific to each vehicle and engine combination.

Some diagnoses are quick and easy. Others are more involved, time-consuming, and difficult. Of course Haven Mobil wants to figure out what’s wrong with your sedan and get you back on the road as quickly as possible.

Rancho Cucamonga California Winter Prep Service For Your Auto

When winter approaches in Rancho Cucamonga California, we break out the sweaters, coats, boots and mittens. We want to be ready for winter conditions. Your vehicle needs to be ready for winter as well. The last thing you want is to get stranded out in the cold. You need your vehicle to be safe and reliable. It’s a good idea to get caught up on any neglected maintenance items anytime – but the stakes are higher in the winter.

There are some specific things that we need to do in Rancho Cucamonga California to have our vehicle ready for winter. The most obvious is having the antifreeze checked. If the antifreeze level is too low, it can’t properly protect your engine, radiator and hoses from freezing. If your car does not seem to be making enough heat to keep you warm, your antifreeze level may be low or you could have a thermostat problem. Get it checked out. If you are due for a cooling system service, now is a perfect time to have it done.

In the cold months around Rancho Cucamonga we always worry about being able to stop in time when it’s slick out. The first thing to remember is to slow down and allow yourself plenty of room to stop. Of course, you want your brakes to be working properly. A thorough brake inspection will reveal if the pads or any other parts need replacing. Check with your service consultant to see if it is time to replace your brake fluid. It accumulates water over time which really messes with your stopping power.

It is a really good idea to have your battery tested. A battery’s cranking power really drops with the temperature. If your battery is weak in the fall, it may not be up to winter. There is nothing like a dead battery in a snow storm.

Which leads us to an emergency kit. You should always have a blanket or something to keep you and your passengers warm if you get stranded. If you will be venturing away from civilization, pack more items such as food and water to help you survive. Keeping at least half a tank of gas is a good precaution if you get stuck and need to run the car to keep warm and it will help keep your gas lines from freezing up.

Winter in Rancho Cucamonga California always makes us think of our windshield wiper blades – usually during that first storm when they aren’t working right. That’s why it’s a really good idea to replace your blades in the fall before the winter storms. If you live where there’s a lot of snow and ice, you might want a special winter blade that resists freezing up. And be sure to have enough windshield washer fluid.

The final thing to consider is your tires. Any tire can lose pressure over time – up to one pound every six or eight weeks. For every 10 degrees the temperature drops you lose another pound of pressure. So if it was 80 degrees outside when you checked your tire pressure two months ago and now it’s 40 degrees out, you could be down 5 pounds of pressure. That’s enough to be a real safety issue and it wastes gas too. You may need special winter tires as well. Your tire professional can help you find the right tire design for your expected road conditions.

If you’re getting winter tires, it is always best to put them on all four wheels. If you are only getting two, have them put on the rear – even if you have a front-wheel drive or four-wheel drive vehicle.

This is a very important safety measure recommended by tire manufacturers. Sliding or fish-tailing on ice and snow is a matter of not having enough traction at the rear end. That is why your newest tires should always be on the rear.
