OBD (ON BOARD DIAGNOSTICS) EVALUATION.
Modern automobiles are equipped with their own troubleshooting systems called On Board Diagnostics, or OBD. These systems take thousands of readings from your car’s sensors, continuously compiling information about how everything’s working. When something is awry, the system sends out a code telling mechanics or you, what’s gone wrong, and often triggers the dreaded Check Engine light. Unfortunately, the language of OBD and OBD-II systems is a bunch of numbers. Use our guide to figure out what your error code number means, what sytem it’s talking about, and what you need to do to fix it.

For brake troubleshooting, Below are some guide for you all.
Troubleshooting Brake Problems – Brake Pedal Too Low
Your brakes are probably the most important part of your car. Without an intake system, you’ll just sit there. But at least you won’t hit a tree while you’re just sitting there! Seriously, brakes aren’t something to play around with. If your car is having a braking problem, whether it’s weak brakes, a mushy pedal, grinding sounds – whatever your brake problem is, you need to troubleshoot and repair it as soon as possible. We’ll help you diagnose your braking problem so you know what repairs to make.
Brake Pedal Goes Too Far Down to Stop. If you step on the brake pedal and it feels like it’s going too far down before you start to slow, you might have the following problems:
Low Brake Fluid Level:
Check your brake fluid. If it’s low, top it off to the mark on the side of the reservoir.
Contaminated Brake Fluid:
Even though your brakes operate in a closed system, contaminants can still work there way into the works. Air can enter the system through the smallest hole, and you can end up with water in the system from condensation and other means. There’s not really any way to check for this, but bleeding your brakes will remove the bad stuff and replace it with new fluid.
Worn Brake Pads:
Your brakes should never wear low enough to cause your brake pedal to feel low, they’ll scream at you before then. But if they do get very low, you might have this problem. Replace your brake pads as soon as possible. Of course, this can be avoided with regular brake inspection.
Bad Brake Power Boost Unit Finally, if your brake booster goes bad you’ll have low brake pedal issues. Most brake boosters are vacuum controlled, so a special vacuum measurement device that connects to the brake booster is needed to check it. If it’s bad, you’ll have to replace the boost unit.
Troubleshooting Brake Problems – Brake Pedal Too Firm
Brake Pedal Too Firm. If you step on the brake pedal and all of a sudden it feels like you’re doing leg presses at the gym with a new personal trainer, your brake pedal may be too firm. This symptom points to a few potential problems, all of which need to be fixed as soon as possible.
Your brakes are easier to press because of a brake booster that gives your foot the strength of 10 men. This booster uses vacuum to help you activate the brakes. If there is a vacuum leak somewhere in the system, it won’t have enough negative pressure to do its job. Check the vacuum system for leaks. If you find none, your brake booster is probably bad and will need to be replaced. This can be tested by a shop if you want to be sure.
Brake Line Obstruction:
It’s possible for something to block brake fluid from reaching a portion of the system. This could be something in the line like a chunk of rust, or it could be a pinched brake line. Visually inspect the brake lines and replace damaged brake lines as needed.
