What is C0C65?

The diagnostic trouble code (DTC) C0C65 is related to the vehicle's advanced driver-assistance systems (ADAS) and typically indicates a malfunction associated with the lane departure warning or lane-keeping assist features. This code is prevalent in various makes and models, particularly the 2016-2020 Toyota RAV4, as well as some Lexus vehicles. When this code is triggered, it signals that the vehicle's onboard computer has detected an issue with the sensors or systems responsible for monitoring lane positioning. This could involve problems with the camera, wiring, or even the software that interprets the data from the sensors. From a real-world perspective, if your vehicle is equipped with lane assist features, you might notice that these functions become inoperative, which can lead to concerns about safety while driving. Ignoring this code may lead to further complications, including accidents due to reduced assistance. Therefore, understanding and addressing DTC C0C65 is crucial for maintaining your vehicle's safety features and ensuring a smooth driving experience.

Symptoms

Common symptoms when C0C65 is present:

  • Check engine light illuminates and remains on, indicating a persistent issue with the ADAS.
  • Lane departure warning alerts may fail to activate or may operate erratically, compromising driving safety.
  • Vehicle drifts out of lane without warning, which can lead to safety concerns during highway driving.
  • Reduced functionality in lane-keeping assist features, leading to increased driver fatigue on long trips.
  • Increased steering effort required to maintain lane position, indicating a potential issue with sensor calibration.

Possible Causes

Most common causes of C0C65 (ordered by frequency):

  1. Faulty or misaligned forward-facing camera, which is responsible for detecting lane markings; likelihood: 40%.
  2. Corroded wiring or loose connections in the lane assist system, which can disrupt the signal flow; likelihood: 30%.
  3. Software glitch in the ADAS module that requires a firmware update; likelihood: 20%.
  4. Unusual tire wear affecting vehicle alignment, which can impact lane detection; likelihood: 5%.
  5. Extreme weather conditions affecting sensor performance, though this is rare; likelihood: 5%.
