Radc Calib Issue
AI status
Completed
Completed
100%
Causes
- Incomplete or failed radar calibration routine
- Contaminated or obstructed radar sensor lens
- Mechanical misalignment or improper mounting of radar sensor
- Corroded, loose or damaged wiring/connectors between radar and control module
- Software bug or corrupted calibration data in control module
- Faulty radar sensor or radar control module
Symptoms
- Driver assistance warning message related to radar or Autopilot
- Adaptive cruise control or collision mitigation unavailable or degraded
- Radar reports invalid or out-of-calibration status in service logs
- False/phantom object detections or missed detections
- Calibration routine fails to complete or repeatedly requests recalibration
What to check
- Retrieve OEM fault codes and event log with Tesla service tool; note timestamps and related faults
- Confirm vehicle software level and recent updates or re-flashes
- Visually inspect radar sensor area for contamination, damage or foreign objects
- Inspect sensor mounting points for damage, correct torque and alignment marks
- Check wiring harness and connector pins for corrosion, bent pins, water ingress or loose terminals
- Verify last calibration timestamp and who/where it was performed
Signal parameters
- Radar module status (calibration state)
- Radar raw/processed target count and ranges
- Last calibration timestamp and technician ID
- Module communication status on vehicle network (CAN/CAN-FD)
- Steering angle, vehicle speed and yaw rate during dynamic calibration
- IMU/gyroscope alignment and offsets
Diagnostic algorithm
- Pull the complete fault log and freeze-frame data with OEM diagnostic tool; note linked faults and exact messages.
- Confirm vehicle software/build version and check for technical service bulletins related to radar calibration.
- Visually inspect radar sensor and surrounding area: clean lens, check for impact damage, and confirm mount is secure and aligned to factory marks.
- Inspect wiring harness and connectors for corrosion, water ingress, loose pins or chafing; repair or replace as needed.
- Verify related sensor health (IMU, cameras, wheel speed) and ensure no other sensor faults could prevent calibration.
- Attempt a factory-recommended static or dynamic radar calibration following the manufacturer procedure; record any error codes/messages during the attempt.
- If calibration fails, swap with a known-good radar module (if available and per safety/service rules) or replace sensor/module when bench testing confirms module fault.
- After repair/calibration, clear fault codes, perform a confirmation drive and recheck logs to ensure calibration status is retained.
- If intermittent or software-related, reflash or update module software per dealer procedures and repeat calibration.
Likely causes
- Calibration data corrupted after software update
- Physical impact or body repair altered sensor position
- Connector corrosion causing intermittent data during calibration
- Sensor returned out of factory tolerance (hardware fault)
- Incorrect or incomplete calibration procedure performed
Fault status
Status
Radar calibration data invalid or calibration failed. Radar-based driver assistance features may be limited until calibration and any required repairs are completed.
Repair difficulty: Medium
Diagnostic time: 1.5 - 4.0 hours
