Faulty Wiring: Damaged or faulty wiring and connectors can cause malfunction. Electric signals cannot flow to and from the ECU and sensors. Corrosion is the most common cause of disrupting the signals that can trigger the warning to pop up.

ABS Speed Sensor: The Drive Start Control relies on the ABS speed sensors to detect the wheel speed. It tells the ECU how fast the vehicle is going. If there is a malfunction within the ABS speed sensors, The Drive Start Control cannot operate properly.

Park/Neutral Position Switch: It is responsible for telling the Drive Start Control which gear position the driver is on for it to know what corrective measures are needed. If the Park/neutral position malfunctions, drivers can experience incorrect gear selection and difficulty starting the car.

Accelerator Pedal: If the Accelerator pedal is malfunctioning, it can give inaccurate signals to the ECU, leading to a problem with the Drive Start Control System’s ability to manage engine power.

Ignition Coils and Spark Plugs: The engine needs ignition coils and spark plugs to operate. Multiple systems might be affected if there is a problem with just one of them. Driver can experience a lack of power, engine misfires, and rough idling.
