What To Do When Cars Say ASC System Service Required?

In current automotive transportation, manufacturers have integrated various smart mechanisms and auto-sensored systems to bring a fascinating driving experience for drivers.

The smooth handling and stability functions always lie on the top priority when considering purchasing a car.

And the ASC system service required arises as the most crucial tool to maintain an effective driving movement.

This article will introduce all-around knowledge concerning a system service required meaning, symptoms, and reasons for a bad ASC system.

In addition, we also show you the proficient approaches to dealing when the ASC system goes off the right track. Let’s jump right in!

ASC System Service Required: What Does It Mean?

asc system service required

Mitsubishi’s active stability control (ASC) system includes three main functions: anti-lock brake system, traction control, and stability control function.

When something goes wrong with this system, the car will send you a warning indicator called ASC system service required on the dashboard. Or the ASC icon will light up to announce unstable handling.

About ASC System

The ASC system takes control over inputs like wheel speed and brake pressure.

Once the traction reduces significantly, ASC also alters the engine power to make up a respective loss force and guarantee the active control of the vehicle.

When the issues relating to ASC arise, the light on the instrument panel will blink to indicate the dangerous situation.

In particular, the amount of wheel slip is insufficient, so you need to slow down for a safe purpose.

The car starts rough then smooths out if you ease the issue with proper solution. Or the traction control function will set off to ensure sufficient pulling force for the engine.

Apart from those problems, a faulty ABS wheel speed sensor is the most common trigger. You must focus on the constant brake pedal squeaking and apply the appropriate fixing method.

In addition, there are other rare situations but still likely to occur, like faulty ABS pump, blown fuse, or defective steering angle sensor.

Better known than never can prevent your vehicle from ASC service required.

Symptoms: Bad ASC System

A wide range of symptoms indicates that your vehicle needs an ASC system service required outlander.

Notice these signs to timely determine the ASC-related issues and have the right mending measures.

An ASC System That Stops Working

The ASC system required can relate to the damaged ABS sensor. The ABS and traction lie on the single module, easily resulting in a loss of an anti-lock braking system.

Thus, it would help to push harder on the brake pedal to reduce car speed or stop entirely.

One thing will lead to another; the vehicle will encounter the high possibility of losing a large amount of traction and ending up with hydroplaning.

On the other side, ABS warning lights come mainly from the sensor. For example, dust or metal strings cause the polluted sensor, thereby reducing the performance of ABS.

In another case, the breakage of sensor wiring triggers the interruption and non-continuity of the ABS.

Traction Light Staying On

We will use the traction control system (TCS) switch to manage the traction properties, which helps drivers to run the car engine according to their intention.

The staying on traction light means that the TCS has gone corrupting or defective. You will find it hard to spin the wheel or switch the traction.

Aside from the light signal, you could also base on the failed module traction control.

This symptom occurs once it is unlikely to turn off the traction switch. You have to fix or replace a whole new button to operate the traction effectively and safely.

Breaking-traction Wheels

Suppose there is any failure happening with the traction control module.

In that case, taking control of the brake pedal is difficult, especially in weather like wet or snow. Then, TCS combines with ABS systems to deal with hydroplaning.

Normally, the start of TCS won’t require that enough hydroplane length. It just happens in case the TCS’s functions go wrong.

Limp-mode Engine

Limp mode provides a safe motor and transmission engine control. With this mode, you can lower the power and limit the RPM of your vehicle.

The car will turn right to the limp mode when something wrong gets detected.

What Are Causes Of A Bad ASC System?

ABS Speed Sensor

This type of sensor transmits the wheel speed issue to the ASC computer.

Because it lies down on the wheel, the possibility of getting submerged in the water is likely to happen commonly. So regular check is necessary to ensure the sensor readings run proficiently.

Brake Pedal Switch

Make sure the brake pedal goes under pressure using the switch signals.

The car won’t kick in without the pressed brake pedal. If you ignore this element, the ASC warning lights will occur immediately.

Electrical Short

ASC warning messages also stem from this unexpected issue – the brake light bulb.

In particular, the corroded connectors and incorrect resistance of aftermarket LED bulbs are the main reasons.

Misalignment

Misalignment means the different sizes in the tire, which leads to the implausible readings of the steering wheel angle sensor. From there, the ASC system can work well based on those malfunctions.

Besides, the 4WD system installed enables your vehicle to prevent any damage. When any unsafe situation happens, the ASC mechanism will notify you quickly with high accuracy.

When you see the non-stop ASC light, your car is facing an extremely dangerous situation. Thus, bring your vehicle to the reliable garage and get them professionally diagnosed.

How To Deal With ASC System Service Required?

When ASC service required Mitsubishi lancer begins, be calm to detect the main trigger and use the appropriate method to solve it properly.

If you want to diagnose the reasons causing the ASC warning light, there is a requirement for dedicated tools.

In more detail, you need an OBD-II ABS scanner for Mitsubishi, which operates as an ABS code reader.

The steps below still work well on the current Mitsubishi versions, especially the 2014 Mitsubishi outlander ASC system service required. Please follow as directed for an effective usage purpose.

  • Connect the ABS scanner to the OBD-II port under the car dashboard.
  • Start the scanner
  • Choose icon Mitsubishi on the menu
  • Choose an anti-lock brake system
  • Choose read code mode
  • Then the scanner will quickly scan all the potential problems
  • Afterward, correct the wrong codes and, of course, pass the stored codes.

How To Manually Turn Off Mitsubishi ASC System

To deactivate the operating ASC system, press the ASC button on the instrument panel in three seconds. Then, the signal light will turn off.

However, we highly recommend you always turn on the ASC mechanism for a smooth driving journey.

Final Thought

Asc system service required plays a crucial role in daily vehicle operating.

Never ignore or skip the notification when the ASC system goes bad. Otherwise, you may end up involved in several unfortunate accidents.

Do the diagnosis process and get your vehicle fixed timely and properly. Hence, you can protect yourself and lengthen the engine control’s life span.

All in all, we hope the information above is useful for you to practice with the Mitsubishi activation.

Thank you very much for reading, and see you in the upcoming article.
