The “Drive Start Control Malfunction Visit Your Dealer” error message in Toyota Camrys is triggered when the drive start control system detects an issue that prevents the vehicle from starting when the gear selector is not in the “Park” position. Common causes of this error include:
Faulty Brake Pedal Sensor: A malfunctioning brake pedal sensor can fail to detect when the brake pedal is depressed, leading to the error message.
Gear Selector Switch Issues: If the gear selector switch is malfunctioning, it may send incorrect signals to the drive start control module, causing the error.
Ignition Switch Problems: Problems with the ignition switch can prevent the vehicle from recognizing when the key is in the “Start” position, resulting in the error message.
Electrical System Malfunctions: Short circuits or loose connections in the electrical system can disrupt communication between the drive start control module and other components, triggering the error.
ECM/PCM Failure: The Engine Control Module (ECM) or Powertrain Control Module (PCM) is responsible for managing the drive start control system. A failure in these modules can lead to the error message.
