ABS WARNING LIGHT ON

When the ABS warning light comes on it means there could be a problem with your anti-lock braking system(ABS). ABS prevents your vehicle's wheel from locking up in a sudden stop which helps avoid skidding out of control especially on wet roads
Though sometimes it could also be the result of a fluke in the ABS system, so when this light comes on and you are driving ' don't panic' find a safe place to pull over, turn off your engine, and then restart the car. If a fluke in the ABS system triggered the warning light, it should turn stay off when you restart the engine but if not, then it's time to get an ABS diagnosis

The most likely reason is failure of wheel speed sensor(WSS) or an issue with sensor's wiring circuit as these will disables the ABS system and causes the ABS warning light to come on

To check the wheel speed sensor you have to measure it's output voltage, you do this by plugging a breakout box into the ABS module's wiring harness and attach the test leads from a digital volt ohm meter (DVOM) to the appropriate pins for the WSS circuit. For a proper wheel speed sensor, an alternating current (AC) voltage reading of 50 to 700 MV is produced when the wheel is spun by hand at about one revolution per second-- but if you have no reading or a low voltage reading then you have to measure the resistance in the WSS circuit. The resistance should be around 800 to 1400 ohms. If there is too much resistance in the sensor circuit, reads open or is shorted (little or no resistance), then measure the resistance across the sensor itself. If the sensor itself reads within specs, the problem is in the wiring or connectors. If not, then you have a bad sensor that needs to be replaced

DRIVING WITH ABS WARNING LIGHT ON

If no other brake system warning lights are on, it means the ABS brake system may not be working, but there should be normal operation from the standard service brake system. It should be safe to drive to a shop as long as you keep in mind that in the case of a sudden stop, the car is more likely to skid or slide.

If there are other brake system lights on in addition to the ABS light, then there could be something wrong with the basic service brake system. It could be something very serious like a hydraulic problem or loss of brake fluid pressure. In this case, IT IS NOT SAFE TO DRIVE

DIFFERENCE BETWEEN FOOT BRAKE AND HAND BRAKE

Motorists around the world know  how to use foot brake and hand brake, even non-motorists are aware of their operation but how many are actually aware of the working mechanisms of braking using the pedal and the handbrake? very few, i guess. So without wasting much time let's break down the difference Foot Brake and Handbrake: The Real Difference If you have always been looking for the answer to- “when should I use handbrake and foot brake,” then delve deeper into their mechanisms and find the appropriate answer? 1. Overview Commencing with the foot brake system, it is a pedal connected to vacuum booster, which is used to stop or slow down the vehicle’s motor. This is also known as the system of hydraulic brakes that multiplies the foot-force applied in order to stop a car weighing several tons. Whereas, the handbrake, also known as the parking brake, or emergency brake; is a straight pull handle near the steering column. This can also be a hand-operated lever...

CABIN AIR FILTER

On newer vehicles you are likely to find the cabin air filter, it's job is to clean the air that enters the passenger compartments and HVAC( heating, ventilation and air conditioning) unit In some cars you will find it located under a panel at the base of the windshield while in other cars you will find it behind the glovebox There are two kinds of designs or construction of cabin air filters and it's maintenance depends on the construction your vehicle is using i. Dust only-- should be replaced every 20,000 miles or two years ii. Dust and odor-- should be replaced every 12,000 miles Note that replacements often depends on operating condition

CHECK ENGINE LIGHT

Check Engine Light officially known as the Malfunction Indicator Lamp(MIL) informs you when there's an emission-related problem with your engine control system. Depending on how critical the problem is, your check engine light may stay on continuously or just flash. It will most likely stay so you don't forget it needs checking If no other warning lights are on, and the engine is running normally (no unusual noises, smells, vibrations, etc.), you can assume the fault that is causing the Check Engine Light to come on is probably minor and won't hinder your ability to continue driving. But if other warning lights are on, you should stop your vehicle, come down and investigate the problem OBD II - HOW IT WORKS When the On-board diagnostics(OBD) detects faults that may lead to an increase in emission, the OBD sets a pending code in the vehicle's memory and if the same problem occurs on a second trip, under same condition the OBD system will then set a diagnostic tr...
