Certified Technicians

Today’s vehicles in Michigan are rolling computer networks with multiple processors, sensors and miles/kilometers of wiring. The mechanical elements — from the suspension to the engine valve train — are extremely sophisticated. Diagnosis and repair is more exacting that ever before. Even a simple tire rotation may involve resetting the tire pressure monitoring system.

Our technicians at Pro Muffler & Brake train hard to stay current on automotive technology, repair best practices and diagnostic techniques. Many have earned multiple certifications in various specialty areas. They obtain training from parts manufacturers, suppliers, independent trainers and recognized certification programs.

In our view, this is all a part of what it takes to be a sustainable business. You expect service and repairs to be done right the first time. We have to deliver that in order to continue to earn your trust and business. And of course, we stand behind our work and the parts we install. Let Pro Muffler & Brake be a part of your family’s car care.

Why Is My Check Engine Light On?

The Check Engine Light strikes fear into the hearts of many in Southwestern Michigan and is totally ignored by just as many.
Let’s get the urgency issues out of the way first. If your minivan’s check engine light is flashing, that means that something is wrong that could cause severe engine damage. Naturally, drivers should get that taken care of right away at Pro Muffler & Brake Shop Inc.

If your check engine light is flashing, you shouldn’t drive at Benton Harbor highway speeds, tow or haul heavy loads.

If the light is glowing steadily, Benton Harbor auto owners should keep an eye on it for a day or two. If the light doesn’t go off, schedule an appointment with Pro Muffler & Brake Shop Inc to get it checked out.

An explanation on how the Check Engine Light works may be informative. Most of your minivan engine functions are controlled by a computer, not surprisingly, called an engine control computer. The computer is able to adjust many engine parameters for environmental conditions, engine condition and even the way you drive.

In order to make these adjustments, the computer relies on a network of sensors to provide data. The computer knows the proper operating range for each sensor. When a sensor reading is out of range the computer runs some tests and may turn on the Check Engine Light.

A simple example is a loose or missing gas cap. This may cause one of the sensors to read out of range. The minivan’s computer doesn’t know if it’s a serious condition that caused the reading or just a loose gas cap, so it stores a trouble code and turns on the Check Engine Light.

Now when you tighten up the gas cap the sensor readings will be in the correct range. The computer will keep checking on the report for a day or two. Since a bad reading didn’t come up again, it turns off the Check Engine Light. The computer will also try to make adjustments to compensate for some readings. If it can do so, it’ll then turn off the Check Engine Light. If the problem can’t be resolved then the light will remain on and you should get your minivan looked at Pro Muffler & Brake Shop Inc.

Your Pro Muffler & Brake Shop Inc technician will plug a scanner into the on-board diagnostic port and read the trouble code stored in the computer. The trouble code will give the Pro Muffler & Brake Shop Inc technician a starting place as he diagnoses the cause of the problem.
