Nowadays, vehicles are more intelligent and self-reliant machines. Vehicles are much more advance in any field whatever you pick. Every part of the automobile has numerous advancements in it. now it comes with the brain. So, that they can perform in the numerous different situations every vehicle nowadays is are multipurpose vehicle.

Now your ride on road is like gliding over the road. If we look back in years the was too bumpier and you must be tired from that if you traveled a long trip. So we are here to discuss ASCs and if you have ASC system service required.

What Does ASC System Mean?

ASC (Active stability control system) is invented to make your ride comfortable. So that you can work without any hesitation in your mind. It is controlling the other stability equipment, for example, ABS (anti-lock braking system), traction control system, and the stability control system also. To notice the defects in that particular system. So that you can prevent the misbehavior of the vehicle and you will about the what are the faults that happen with your vehicle.

How Does ASC work?

As we discussed that it is controlling or we can say it communicates to give the command to the other equipment which works for the stability of the vehicle on the road. It controls the ABS, Traction control system, and the stability control system.

1. ABS (Anti-Lock Braking System)

It is the very basic function in every vehicle and generally comes with every vehicle nowadays. It is very elementary and very basic to make the controlled stability in your vehicle. That works to control the brakes to the wheel jamming during braking. If you are in a panic situation and applied the panic brake then it is responsible for not jamming the brake means before jamming the wheels it releases the brake and is applied again and operated in milliseconds. Also, give improved braking and make your vehicle stable on the road or slippery surfaces.

2. Traction Control System

This system also controls the stability of your vehicle during acceleration. Because if accelerate hard to the vehicle then there are possibilities of slipping of vehicles on the road and causing the accident to yourself. This system also uses brakes to control the stability means when you get started with your vehicle. When you give the hard acceleration to your vehicle initially then it applies the brake to control that extra power on the wheels. That can cause the slipping of the vehicle on the road or slippery surfaces.

3. Stability Control System

The stability control system is the advance to stabilize the vehicle on the road or the slippery surface. You can say the traction control system is a part of stability control not vice-versa. The stability control system works on the engine as well as on the brakes to control the vehicle’s stability. When you accelerate your vehicle hard then it will reduce the power at the engine and also use the brake to control wheel behavior. according to the surface. 

After controlling these systems then ASC monitors engine power, brake pressure, and wheel speed. And controls the loose traction situation. So that your vehicle maintains the ample amount of traction that is necessary to be on-road without slipping of wheels.

Symptoms Of Bad ASC System

There is a proper message that comes on the DIC (Driver information cluster) that denotes that there is a problem with your ASC system. And following are the events that happen when you have a bad ASC system:

  1. ASC Service Required light (at the DIC) comes on.
  2. When driving in unsafe conditions, the ASC light won’t blink- blinking is the indicator when you drive on a slippery surface that ASC is in working condition.
  3. The ABS doesn’t engage under a panic stop.
  4. You have a loss of traction due to the 4WD being disengaged again and again.
  5. ASC System Service Required — message showing on the DIC.
  6. Noticeable wheelspin — when the traction is poor and on the steeps.
  7. Loss of traction — either oversteer or understeer. 
  8. The engine does not start—and also triggers the ASC warning message. 
  9. A 4WD system won’t be operable  —on vehicles equipped with permanent all-wheel-drive systems. 
  10. Cruise control won’t work. — The cruise control isn’t enabled. 
  11. Automatically gets ASC Off Transmission will be stuck and you will no longer change gears. 
  12. ASC light flickery with sound for several minutes when you start to drive.

Can We Control ASC On/Off Manually?

Yes, you can operate the ASC on/off manually when you start the vehicle then it will automatically start. When you stop the vehicle with the ignition on then you need to switch off the ASC System to prevent its contribution by the dedicated switch given near the steering. But make sure it is always in condition when you driving, especially on slippery surfaces.
