2022 R1S Driver+ Assist System Errors - Constantly Unavailable

Vehicle: 2022 Rivian R1S Launch Edition

Hey everyone,

My 2022 Rivian R1S Launch Edition has been giving me constant trouble with the Driver+ assist system. For the past few weeks, I've been getting frequent messages like 'Driver+ Unavailable' or 'Driver+ Sensor Blocked' even when the sensors are perfectly clean and there's no obstruction. Sometimes, it works for a few minutes, then just cuts out again. It's making highway driving, where I rely on adaptive cruise and lane keeping, really frustrating.

I've tried cleaning all the camera lenses and radar sensors meticulously, restarting the vehicle, but nothing seems to make a difference. It feels like a deeper electrical or sensor calibration issue. Has anyone else experienced these persistent Driver+ errors on their R1S? What was the resolution? I'm hoping it's not a major sensor replacement job.

ClearTheCode admin answer:

Driver+ assist system errors can be concerning, as these systems rely on a complex array of sensors, cameras, and processing units to function safely. Persistent 'Unavailable' messages, especially when no physical obstruction is present, point towards an underlying electronic issue.

Possible Causes:

  1. Sensor Malfunction: One or more of the radar, ultrasonic, or camera sensors could be faulty or sending incorrect data to the control module.
  2. Wiring/Connectivity Issue: Damaged or loose wiring harnesses connecting the sensors to the main control unit can lead to intermittent data loss and system errors.
  3. Control Module Fault: The main Driver+ (or ADAS) control module itself could be malfunctioning, failing to properly process sensor inputs or output commands.
  4. Calibration Issue: After a minor impact, windshield replacement, or even sometimes spontaneously, sensors (especially cameras and radar) can lose their precise calibration, leading to incorrect readings and system deactivation.
  5. Software Glitch: A bug in the vehicle's software could be causing the system to incorrectly interpret sensor data or prematurely disable Driver+.

Common OBD Codes (Rivian-specific codes will be more precise, but these are generic examples):

  • U0401: Invalid Data Received from ECM/PCM A (generic communication error).
  • C0051: Steering Angle Sensor Performance (if related to lane keeping).
  • B1000: Generic Electronic Module Fault (can indicate a problem with the ADAS control unit).
  • Specific codes related to individual radar, camera, or ultrasonic sensor failures.

Troubleshooting Steps (Limited):

  1. Ensure Clear View: Double-check all camera lenses (windshield, side mirrors, front/rear) and radar sensors (front bumper, rear bumper) for any smudges, dirt, or ice, even if you think they're clean.
  2. Software Update: Verify that your Rivian has the latest software updates, as these often include bug fixes for ADAS systems.
  3. Document Conditions: Note down exactly when and where the errors occur. Is it specific speeds? Weather? After a certain time? This information is vital for diagnostics.

When to See a Shop:

  • Immediately. Persistent Driver+ errors, especially if they affect safety features like adaptive cruise control or emergency braking, should be addressed by a service professional.
  • If the issue does not resolve after ensuring all sensors are clean and the software is updated.
  • If you receive specific warning messages that advise service.

Diagnosing ADAS issues requires specialized tools to read sensor data, check module communication, and perform sensor calibrations. A Rivian service center will be able to perform a thorough diagnostic and determine if a sensor, module, or calibration is needed.
