"Why is my check engine light on?" This is a
common question our customers ask. Generally it means the engine has run a self-test and has found that something isn't working like
it should. What should you do about the check engine light? The best
answer is to get it looked at as soon as possible. The longer the light
stays on, it's likely that your problem is going to get worse.
What makes a warning light come on?
Today's
vehicles are manufactured with a multitude complex inter-related systems. On-board
computer systems continuously monitor and store detailed diagnostic information about the
performance of these systems. A warning light comes on because the
computer received a signal from one of the systems or components that exceeded its normal operating range. The computer then sends a
signal to turn on the light to let you know something is wrong! (That's some fancy technology, huh?)
Some
of the most common causes for a check warning light are:
- not properly
tightening your gas cap to engine
- transmission issues
- ignition problems of some kind
- Performance issues with your braking system
While warning lights can go on and the car
still appears to be driving "fine", ignoring some lights can lead to
serious issues, such as engine damage or other component failure. In
some instances, this can be a safety hazard. That's why it is
recommended to be safe (give yourself peace of mind) and have your car
looked at by a certified professional as soon as possible.
How does Hyundai Albuquerque "diagnose" my problem?
At
Larry H Miller, we have the tools, training and technology to handle
diagnostic issues, such as a Check Engine light. Properly performing a
complete diagnostic procedure normally includes the following steps:
1. RETRIEVE DATA -
A diagnostic tool connects to the vehicles' on board computer to
review error codes. Several years ago, the auto manufactuers came together and made these codes universal. That means that the code for a loose gas cap is the same on a 2014 Hyundai as it is on a 2014 Ford. This gives us a general idea of the system that may
be failing/malfunctioning.
2. VERIFICATION TESTING -
This test determines if the physical test matches the digital
test. Some systems may have a simple problem like a leaky seal on a hose or may have a more complex problem.
3. PINPOINT TESTING -
Beside general systems test, pointed tests are typically required. This
entails inspecting specific components for failure. This result gives the tech a very specific results so he or she knows exactly what the problem is.
4. RESEARCH TECHNICAL SERVICE BULLETINS -
Technical Service Bulletins and hotline information indicate if
the problem is part of a "pattern failure". A pattern failure
is a known issue that occurs with a particular type of vehicle. This
does not eliminate the need for testing as other systems must meet
specifications before a service bulletin procedure should be performed.
5. SUGGEST NECESSARY REPAIRS - Sometimes we find your vehicle needs other repairs while we're doing your diagnostic. We'll tell you what we found along with a recommendation. You'll tell us what you want fixed.
6. CAR REPAIR - We will perform necessary fixes including replacing parts, cleaning components, or performing updates.
7. VERIFY REPAIR -
Once all necessary actions have been taken, the vehicle must be
retested to verify that the repair is complete and has achieved the
proper results.
