Drive Start Control Malfunction

There are a lot of crashes because of sudden starting or stopping after shifting the wrong gear or pressing too hard on the accelerator.

A car safety system called drive-start control was developed by Toyota to mitigate damages from accidents. Is it as strong as we think it is?

There were some complaints on the Internet about the malfunction of the drive start control. In our article, we will find out what it is and how to deal with the drive control malfunction.

What Is a Drive Start Control System?

Misapplication incidents in the car can lead to serious accidents each year.

To create a competitive advantage over its competitors, Toyota has added new safety features to its vehicles, such as a drive start control system.

The introduction of the Drive start control system can be considered an important step in improving the safety of Toyota models.

The input of the engine as well as the output power will be controlled by this system when there is a sudden change in the brake system.

The car will accelerate suddenly in the opposite direction if the driver becomes flustered from approaching an obstacle and shifts gears with the pedals pressed.

The operation information and vehicle speed will be analyzed at that time by your engine computer.

After that, the output of the data engine is controlled so that the speed and acceleration are kept below a certain level.

There is a reduction in the sudden start or acceleration conditions.

When the driver causes the car to accelerate suddenly, Drive-start Control will control the engine power to help the car operate in normal mode.

On models with the continuously variable transmission, Drive-start Control is especially useful for inexperienced drivers.

A warning light is displayed on the dashboard and the engine power is reduced if the drive start-control system discovers that the wrong gear has been selected while the driver is pressing the gas.

Common Reasons

Why don’t we know there are problems with your drive start control? What causes the drive start control to malfunction is the most important thing.

A warning light on the dashboard of a Toyota car is the most obvious sign you can see.

It can be accompanied by a combination of other symptoms if it is related to a lot of other problems in the car. It is time to find the reasons.

Ecu Faulty

When the engine control unit malfunctions, it can make a DSC error.

To calculate and manage the timing, speed, idling, and so on, your vehicle gets input from various sensors, and it is the brain of your vehicle.

The Electronic ERG valve and purge valve are examples of the various valves it controls.

A bad ECU can cause the engine computer to receive the wrong data or delay when transferring information from the DCU, which can prevent the engine from starting.

Bad Ignition Coil

The purpose of the coil is to change low voltage into high. The computer tells the ignition system and spark plugs when to ignite the air and fuel in the combustion chamber.

The most optimal time to ignite the air and fuel mixture is determined by the data gathered from various engine sensors and the timing of the firing.

This will help improve the performance of the engine. Engine misfires, lack of power, check engine light flashing, rough idling, slow acceleration, and stalling are some of the things the driver will see when this part is failing.

The effects of the system will be disabled at that point.

Faulty Fuse 

There is a chance that the drive control malfunction is caused by the fuse problem.

Fire and explosion can be caused by car fuses, they are responsible for protecting electrical equipment on vehicles.

The device will be protected by the fuse when the Ampere increases suddenly.

You have a wide range of electronic devices in your vehicle that depends on the charging system’s voltage.

Modern computer-controlled vehicles have a lot of electrical problems that can be caused by a blown fuse.

The components of the battery or central engine unit are related to some of the relays. You might experience a breakdown of the DSC system if the fault lies within the fuses.

Abs Sensor Error

An ABS sensor is used to detect the speed of each wheel and transmit a signal to the slip control ECU.

The vehicle is in operation for a long time when it is mounted near the wheel.

Dirt can cause the sensors to become dirty, which can affect the quality of work and make the indicator light up.

The action that transfers from the drive control system is not allowed to be received and adjusted when the ABS fails.

Bad Car Battery

A bad battery can cause the control system to break.

Car batteries act as a secondary source of electricity, storing and converting energy into electricity to supply equipment on the vehicle.

When the generator isn’t fully charged when the vehicle isn’t starting or the electrical equipment on the vehicle isn’t working.

During that time, the battery will provide power. If the car battery does not have enough power, it will cause the engine to stall or start later than usual.

Solutions

What would happen if your system doesn’t work right? There is a chance the car will not start. The vehicle may be unable to reach high speeds because it is underpowered.

The vehicle could be less stable and more prone to skidding. What are you going to do?

Pull over and take your car to the technician when the warning light appears on your dashboard. There are several solutions that you can use to deal with this phenomenon.

Clean the ABS Sensor

The wheel speed is received by the part that sends the signal to the system controller. If the car runs on bad roads, the sensor may be damaged or blocked.

You can clean the sensor with a soft towel after the sensor. Water and detergents can cause unwanted touch to the sensor.

In rough environments, the ABS sensor is a precise instrument.

It can provide accurate signals when the vehicle is moving at high speeds but a strong impact can damage the sensor irreparably and we need to keep this in mind.

Check the Wiring

Most Toyota owners who experience Driving Start Control problems find the root of the problem to be the wiring on their vehicle.

The other parts of your car should also be spared from the unwanted conditions that happen to the DSC system. The actual function of your vehicle will be influenced by the wires.

Some plugs and cords are disconnected. If you find a broken wire, you can either fix it yourself or have a specialist do it.

Replace the Blown Fuse

The same thing as having your car run without problems the moment you start it is a perfectly functioning car fuse.

It’s important to know how to replace the fuse in your car if the electrical equipment in it stops working. A blown fuse can happen at any time.

If an overload is detected or the circuit malfunctions, the fuse will blow. It would be great to have a trusted mechanic fix the blown fuse.

If you haven’t already, there’s no reason you shouldn’t teach yourself how to change a fuse in your car.

Conclusion

If you don’t drive a Toyota, you probably aren’t aware of the DSC system. The drive-start control system is a unique feature of Toyota vehicles.

Don’t have the system if you are driving a Toyota right now. Your model may have been around for a while.

To protect as many people as possible from accidents caused by pedal misapplication. Safety technologies developed by Toyota meet the needs of the drivers.

Through this topic, you will hopefully learn more about the safety system. When the drive starts control malfunction you should collect useful information.
