If you see a warning light, don’t ignore it book it in to Howick Auto Electrical for repair. We’ll use our diagnostic equipment to scan your warning light system and find out where the problem is. The sooner we identify the problem, the sooner you’ll be moving again. Unsure about what those lights mean? Below are the most common ones:

car electronic diagnostics - abs

ABS LIGHT

The four-wheel ABS or Anti-lock Braking System is designed to help the driver maintain steering control during hard braking, especially in slippery conditions.

How it works

Imagine, you are driving a car without ABS on a slippery road (e.g. after a rain or snow). Suddenly, you notice something on the road right in front of you. You hit the brakes, and try to turn aside, but the steering doesn’t work. The car just skids out of control. Why? Because all the wheels are locked up while you are holding down the brake pedal. As a result, you lose the ability to steer the vehicle.

The four-wheel ABS can help in situations like this. It prevents the wheels from locking up, helping you maintain steering control during braking. In a similar situation, driving a car equipped with four-wheel ABS, it would be easier for you to steer your vehicle while braking.

If the ABS light illuminates when driving, it indicates a malfunction. Have this checked as soon as possible. You will also be unable to get your WOF if this light is on.

Howick Auto has earned its reputation in repairing such faults, we have the latest scan tools and technology to diagnose all ABS faults.

Have the vehicle checked by Howick Auto, as soon as possible.

car electronic diagnostics - brake fluid light

BRAKE FLUID LIGHT

This light will remain illuminated when the handbrake is engaged. Illumination after releasing the handbrake may indicate low brake fluid level.

Refer to the handbook and add the correct brake fluid at once to bring the level up to the MAX mark. As the brakes wear the fluid level will slowly drop. Check your brake fluid level frequently to ensure there is no further rapid loss of fluid.

If the brake fluid is too low and brake pedal travel is distinctly longer than usual, one of the two hydraulic brake circuits may have failed. Do not continue your journey and seek assistance.

If the light remains illuminated, even though the brake fluid level is correct, this may indicate a sensor fault. Take your vehicle to Howick Auto, as soon as possible.




car electronic diagnostics - oil pressure

OIL LIGHT

This light should illuminate when the ignition is switched on and should extinguish as soon as the engine starts.

If the light stays on after starting or illuminates during a journey, stop immediately, switch off the engine and check the engine oil level.

Top up straight away if the level is low.

If the warning lamp illuminates, even though the oil level is correct, do not start the engine CALL HOWICK AUTO.




car electronic diagnostics - battery light

CHARGE LIGHT

This light should illuminate when the ignition is switched on and should extinguish as soon as the engine starts.

If it does not illuminate at all, or if it illuminates while driving, your battery is not being charged as there is a fault with your charging system.

This may be due to one of the following

  • slack battery or starter terminals
  • a broken or loose alternator drive belt
  • an alternator failure

If the drive belt is broken, it must be replaced before you restart the engine. The coolant system may rely on this belt and its failure could cause the engine to overheat, in turn causing engine damage.

Immediately move the vehicle to a safe location and switch off the engine. Do not restart the engine.




car electronic diagnostics - brake pads light

BRAKE PADS LIGHT

This BMW warning light is to alert you there is a likely problem with the brakes, BMW have brake pad sensors that are automatically activated when brake pads are low.
