On Board Diagnostics for Your Engine

Starting in 1996, Corporate Autoworks service technicians have been able to use a standardized diagnostic system to help determine what is wrong with a vehicle. This diagnostic system works in tandem with the Engine Control Modules for each vehicle's engine. The Engine Control Module is a computer that monitors and controls many engine functions.

Sensors throughout a vehicle send readings to the Engine Control Module. These readings help the computer make adjustments in various vehicle systems to allow for constantly changing driving conditions and even to compensate for minor problems. However, if the computer encounters a situation it can't adjust for, it turns on the Check Engine light. (The Check Engine light is called the “service engine soon” light on some vehicles.)

If the Check Engine light is burning steadily, it indicates a problem that needs to be taken care of soon. If it is flashing, however, the vehicle needs immediate attention at Corporate Autoworks. When the Check Engine light is flashing, the vehicle should not be driven at high speeds, haul heavy loads or tow a trailer. Burlington drivers need to understand that doing so can cause major damage.

When a vehicle is brought to Corporate Autoworks in Burlington because the Check Engine light is on, a technician will scan the Engine Control Module to learn why it turned the light on. The answer comes as a “trouble code.” The technician has access to software that allows him to enter the code and find out what it means. The software will also let your Corporate Autoworks technician know what might be causing the problem and how to diagnose it.

Notice that the trouble code does not tell your technician at Corporate Autoworks exactly what is wrong with the vehicle. It can only let him know where to start looking to find the problem.

Scanning a trouble code and determining what it means is fairly simple for the pros at Corporate Autoworks. But the ensuing process of actually diagnosing a vehicle's trouble can take a skilled technician some time. Sometimes this can add up to a significant repair bill. Some vehicle owners mistakenly believe  that the “trouble code” is all they need and think they can then fix their vehicles themselves. Some have tried to save money by purchasing an inexpensive scanner, or they take their vehicles to an auto parts store that offers the scan for little or no cost.

These options are often not the money-savers they seem for Burlington vehicle owners. They can end up costing the vehicle owner extra in unnecessary repairs and engine damage.

For example, the trouble code P0133 reads “Bank 1 sensor 1 circuit slow response.” Translated, that means the front oxygen sensor shows a slow response time in changing the mix of air to fuel. The seemingly obvious conclusion is that the sensor needs to be replaced. The vehicle owner purchases a sensor, installs it and happily goes on his way.

However, read the trouble again: a slow response time in changing the mix of air to fuel. Nowhere does this indicate that the sensor is bad. There are a lot of parts involved in changing the air-fuel mix, any of which could be causing a slow reaction time. Those include a bad or contaminated airflow sensor, an exhaust leak, a problem in the electrical system or a leak in the intake manifold. The sensor is merely relaying that the response time is slow; it doesn't indicate where the trouble is.

So the vehicle ends up with an oxygen sensor it did not need, and the delay in repairing the actual problem may have led to further damage to the engine. Both are added costs for the vehicle owner.

Cheap scanners also don't have the ability to read the history stored in an engine's computer. This operating history contains clues that can help in diagnosing engine trouble since it can indicate a developing problem. Corporate Autoworks invests a lot of money in high-end diagnostic equipment so that we have access not just to service codes but also to the operating history of the engine.

On-board diagnostics, then, are a tool to help diagnose what is wrong with a vehicle. They cannot specify what part needs to be fixed or replaced, and they cannot replace a well-trained and well-equipped service technician.

Unless you are a trained mechanic, it's good auto advice to use Corporate Autoworks for your car care. In the long run, it can save you time, unnecessary expense and frustration. Corporate Autoworks can also help you keep up with your scheduled preventive maintenance, which can also save you on repair bills by alerting you to potential problems before they get expensive.

The Maintenance Free Myth

Sometimes we hear people in Burlington say, "What's up with all this maintenance stuff? Modern cars just don't break down." While it is true that today's vehicles are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most Burlington drivers don't realize how high tech automotive fluids have become,  fluids such as engine oil, transmission fluid, coolant and brake fluid.

Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today's automotive fluids contain a much higher percentage of additives to protect your vehicle's components from premature wear and corrosion. Time and distances march on for all of our cars. Please don't think we're using scare tactics to get you to take care of your maintenance - but here are some personal stories we've heard to emphasize and show how important it is to get things done when they are due. Names are withheld to avoid embarrassment to those who should know better. Even though they should know better, it usually comes down to real life: time and money. But they are tales of a stitch in time saves nine.

The first comes from someone who bought a used pick-up truck for his son. The oil was clean and all the fluids were topped off. A short time later, the truck overheated on a highway in ON and shut down. The repair shop diagnosed the problem: the radiator pan was corroded and dumped the coolant. Even though the coolant level was correct, it was clear that the coolant had never been completely replaced - just topped off from time to time. While this kept the engine cool, all of the anti-corrosion additives had worn out; the coolant became acidic and ate through the radiator pan. The cost: hundreds of dollars and four days in the shop. This demonstrates the need to get your coolant exchanged on schedule.

Another story involves the true cost of skipping an annual inspection. This guy took his SUV in for the ON safety inspection to renew his registration. At the Burlington inspection station, he learned that the law had changed and that his newer rig only required an inspection every two years. He was very happy to save the money. The problem was, his rear brake pads were very worn. Two months later, it was bad enough that he could hear the grind - over the radio, DVD player and the kids. He took it in to get the bad news. Both of the rear brake rotors were damaged. The left one could be resurfaced. The right had to be replaced. So saving a little on his safety inspection turned into an extra $500 over what brake pad replacement would have been. Moral of the story for Burlington drivers: don't skip your annual inspections. The irony is that many Burlington service centers would have done a brake inspection for free.

Next: a teenage daughter and a curb. Daddy's little princess smacked a curb when she turned into a shopping center and popped the tire. The problem came when Dad didn't get an alignment. The impact was hard enough to ruin the tire - so it was enough wreck the alignment. But instead of an alignment after the first tire, Papa ended up buying a second tire a few months later - and then an alignment.

Situation: son and wife with cars from the same vehicle manufacturer with essentially the same engine. Our staffer checked the son's maintenance schedule and saw that it needed a timing belt replacement at 90,000 miles/145,000 km. He had it done - it cost several hundred dollars. His wife's car had about 60,000 miles/97,000 km, so it should be ok for a while. Right? Wrong. The problem was that the wife had the turbo charged version. Its belt was scheduled for replacement at 60,000 mi/97,000 km. At 63,000 mi./101,000 km, the belt snapped on the interstate. The valves all crashed down into the cylinders at high speed, the entire head was shredded and it had to be replaced. The cost: several thousand dollars. Does he wish he had checked the vehicle manufacturer’s maintenance schedule? You bet he does - every time he passes a big-screen TV.

The team at Corporate Autoworks in Burlington recommends taking care of little things before they become big things. And when you take care of the little things, you can make your car run better.  Plus, it is more economical to operate in ON. Remember to save those maintenance records. It'll show potential buyers that you've taken care of your vehicle and it will help you get a better price. Or when you buy a used car, check those records. If there aren't any, assume that the maintenance hasn't been done and take it to Corporate Autoworks in Burlington for an inspection. Take care of unperformed routine maintenance sooner rather than later.

When "Oh, no!" Turns Into, "All right!"

Things we don't expect happen to our vehicles. And let's face, no one really wants to spend money on an unexpected repair. But if you are putting off going to your vehicle repair facility because you're dreading bad news, you might just be putting off some good news.

There was one minivan driver who'd had the same van for years and never had a problem with the power sliding doors.  Then one day, the electrical switches in the door pillars stopped working.  The key fob would still open them, but the door switches wouldn't do a thing.

Of course, the van driver feared the worst: an electrical problem, a major computer failure, mice chewing up the wires.  So, he put off going into the repair facility for a couple of months.  One day, it was time for his regular oil change and the service advisor asked him if there was anything else going on with the van.  The owner mentioned the door problem but said he didn't want to spend a fortune on it.

He waited for his van, and it wasn't long before the service advisor came out with good news. The doors weren't working because a switch on the overhead console had been turned off.  (It was a safety feature to allow parents to disable them.) The owner had accidentally switched it when he was unloading the van.  It was the first thing the technician had checked. Flip the switch back and all was working as usual.

Another example? A mother was driving a minivan with her two kids inside on a hot day when she felt the front end shaking violently as she drove down the road. Fearing something major had broken in the van (and fearing for the safety of her kids), she pulled into a fast-food restaurant parking lot and started to look underneath to see if it was anything obvious she could see.

She couldn't see any broken parts, but she also didn't feel safe getting back in the van with her kids.  So, she called her local service facility and asked if they could send someone to look at it.  When the technician arrived, he took it for a test drive on the same road on which she'd described having the trouble.  Then he put her van up on the lift.  His conclusion?  Nothing was wrong with her van.  It was the street she was driving on.  Crews repairing it had left the surface full of potholes, and that was causing her rough ride.

Ultimately, what these two drivers feared would be an expensive trip to the shop resulted in each driver getting different news than they had expected.  One learned something new about his vehicle.  The other?  Well, the technician saw that her tires were badly worn and convinced her to get them replaced, perhaps preventing an accident and giving peace of mind for a mom with two kids.

I Can See Clearly Now: Wiper Blade Replacement in Burlington

About 90% of our driving decisions in the Burlington area are based solely on what we see. So having a good pair of windshield wipers is extremely important.

Most Burlington drivers have experienced the frustration and fear of not being able to see clearly during a storm, or when our vehicle windshield is just dirty. In fact, it's estimated that 46,000,000 drivers across the nation are driving with wipers that can't adequately clear their windshield in a storm.

It seems like our wiper blades are always at their worst when we need them the most. If that sounds like you, you've got plenty of company in the Burlington area. 78% of drivers only change their wiper blades after the blades function so poorly that they become a safety hazard.

Burlington drivers need to change their thinking. Instead of blades being something to replace when they fail, we need to consider wiper blades as vehicle safety component. Then we'll stay ahead of the storm.

Burlington vehicle owners really ought to replace wiper blades twice a year; in the spring and the fall. If you live in the colder parts of ON, you may even want to get special winter blades in the fall.

Winter blades are made to resist freezing. Speaking of winter and freezing Burlington conditions, if your vehicle has been sitting for a long time and the windshield becomes frozen, don't use your wipers to clear off snow and ice. That can shred your blades and may even damage the wiper motor.

Your wiper blades live outside in the freezing cold and blistering sun. Over time, they become hard and brittle, and then tear. They also lose their flexibility and just don't clear the vehicle windshield effectively. Worn wiper blades aren't just a safety hazard for Burlington drivers; they can also scratch their windshield. That may require replacing the entire vehicle windshield – that's the consequence for neglecting such a small part.

Corporate Autoworks recommends Burlington drivers replace worn blades right away. We can provide you with a quality replacement blade. At Corporate Autoworks, they cost about the same as they would at the store – but installation is included.

Of course you also need washer fluid to help your blades do their work. Even though Corporate Autoworks will top off the washer fluid with a full service oil change, it is a good idea to have some extra fluid at home. Take it with you if you're heading out on a road trip.

Always use windshield washer fluid. Plain water, even that fancy French bottled water, just doesn't cut it. It can freeze in the fluid reservoir or on the windshield itself, making things worse. Besides, water won't clean your windows as well.

So follow these tips to keep your windshield clear and your eyes on the road.
