Code U0235 Description

The U0235 code indicates that the vehicle's onboard computer has lost communication with the cruise control front distance range sensor. This sensor is responsible for detecting the distance between the vehicle and the vehicle in front of it, allowing the cruise control system to maintain a safe following distance. When communication with this sensor is lost, it can lead to the cruise control system malfunctioning or becoming inoperative. This can result in issues with maintaining a consistent speed, following distance, and overall driving experience.

Common Causes of U0235

  1. Faulty front distance range sensor.
  2. Wiring or connector issues leading to poor communication.
  3. Corrosion or damage to sensor components.
  4. Electronic control module (ECM) communication issues.

Symptoms of U0235

  1. Cruise control not working properly or not engaging at all.
  2. Inconsistent speed control while using cruise control.
  3. Warning light on the dashboard related to cruise control.
  4. Decreased fuel efficiency due to lack of optimal cruise control functionality.
  5. Vehicle may not be able to maintain a safe following distance automatically.

How to Fix U0235

  1. Begin by diagnosing the specific cause of the communication loss, using diagnostic tools to pinpoint the issue.
  2. Inspect the wiring and connectors related to the front distance range sensor for any damage or corrosion, repairing or replacing as needed.
  3. Test the front distance range sensor itself to determine if it is faulty, replacing it if necessary.
  4. Check the ECM for any communication issues and reprogram or replace it if needed.
  5. Clear the diagnostic trouble codes from the vehicle's computer and test the cruise control system to ensure proper functionality.

Cost to Fix U0235

The cost of repairing a lost communication issue with the cruise control front distance range sensor can vary depending on the specific cause of the problem and the make and model of the vehicle. On average, you can expect to pay anywhere from $200 to $500 for parts and labor. It's important to note that additional costs may apply if other components need to be replaced or if there are underlying issues that need to be addressed. It's recommended to get a detailed quote from a qualified mechanic to accurately estimate the repair costs for your vehicle.

Tech Notes for U0235

When there are problems with the way different systems in a vehicle communicate with each other using a technology called Controller Area Network (CAN) communication, Diagnostic Trouble Codes (DTC) are displayed. These codes can be caused by issues with the main bus or branch of the communication network, or with the Electronic Control Units (ECUs) and sensors that make up the different systems. If you see code for both the CAN communication problems and internal or power source problems at the same time, you should focus on fixing the internal or power source problems first.
