When Your Air Bag Light Comes On (Illuminated Air Bag Light)

There are some dashboard lights you should pay more attention to than others.  One is the air bag light.  If it's on and your vehicle is in an accident, your air bags probably won't do their job.

Automakers began installing air bags in the late 1990's since they were mandatory in the United States, and manufacturers have included them in Canadian vehicles as well.  Safety experts say using a seat belt in combination with an air bag gives passengers the best chance of surviving a crash and minimizing serious injury.

The air bag warning light takes a few different forms.  Some look like a picture of a belted passenger with an inflated air bag from a side view.  Or there may be a warning light that says something like "Air Bag," "SRS" (for supplemental restraint system), "Airbag Deactivated" or "Air Bag Off."

Different things cause the air bag light to come on.  Your vehicle may have been in an accident during which, while the air bags didn't inflate, crash sensors were activated.  Some of them may be connected with your vehicle's seat belts.  A technician can reset the air bag if this has happened.

Fuses can also blow which will cause the air bag light to come on.  Another possible cause? A sensor that tells the vehicle's computer whether or not there is someone riding in the passenger front seat may be malfunctioning. 

Air bags are not for the do-it-yourselfer.  They are sophisticated systems that require specialized training and equipment to diagnose and repair.  If an air bag light is on, take it to a qualified service repair facility.  One more thing: remember that safety experts have designed air bags to work in conjunction with seat belts for maximum protection in accidents.  So always wear your seat belt.

Du Quoin Drivers: Is It Time to Replace Your PCV Valve?

The crankcase is the lower part of the engine where the crankshaft is housed and where the engine oil lives. The crankshaft is connected to the pistons that power the engine.

When you are diving around Du Quoin, fuel is burned in your vehicle engine, it pushes the pistons down and the crankshaft rotates and sends power to the transmission. Some of the explosive gases from combustion squeeze past the pistons and down into the crankcase.

Now this gas is about 70% unburned fuel. If it were allowed to remain in the crankcase, it would contaminate the oil and quickly turn it to sludge. Sludge is like Vaseline and clogs passages in the engine, leading to damage.

Also, the pressure build up would blow out seals and gaskets. So in the old days, there was just a hose that vented the crankcase out into the air. Obviously, not good for our air quality in Du Quoin, IL.

Enter the PCV valve. It's a small, one-way valve that lets out the gases from the crankcase and routes them back into the air intake system where they are re-burned in the engine. Fresh air comes into the crankcase through a breather tube. This makes for good circulation in the crankcase. And that gets the air out. As you can imagine, however, the valve gets gummed up over time.

Your vehicle manufacturer usually recommends they be changed somewhere between 20,000 to 50,000 miles/30,000 to 80,000 kilometers. Unfortunately, PCV valve replacement is left out of some vehicle owner's manuals, but your friendly service advisor at McPherson Automotive, we will make sure your PVC is replaced if needed.
