Common Problems and Symptoms

1. False Alerts

   • Symptoms: The parking sensors issue warnings or alerts even when the vehicle is not near any obstacles.

2. No Alerts

   • Symptoms: The parking sensors do not provide any warning alerts when an obstacle is detected.

3. Inconsistent Functionality

   • Symptoms: The sensors work intermittently, providing alerts sometimes and failing at other times.

4. Sensor Damage

   • Symptoms: Physical damage to the sensors due to impact, weathering, or scratches leading to malfunction.

5. Calibration Issues

   • Symptoms: The sensors appear to detect objects inaccurately, leading to incorrect distance readings.

Tools Required

• Diagnostic Tool: Tesla Toolbox or OBD-II scanner
• Multimeter: To check voltage and continuity
• Torque Wrench: For reinstallation of components
• Screwdrivers (Phillips and Flathead)
• Trim Removal Tools: To avoid damage when accessing the sensors
• Clean Cloth: For cleaning the sensor surfaces
• Electrical Contact Cleaner: For cleaning connector terminals

Repair Instructions

1. False Alerts or No Alerts

• Step 1: Perform a visual inspection of the sensors for dirt or obstructions. Clean the sensor surfaces with a soft cloth.
• Step 2: Check the wiring harness for loose connections. Re-secure any loose connectors.
• Step 3: If the issue persists, perform a reset of the vehicle's system by powering down the vehicle completely (go to Controls > Safety > Power Off, wait for 2 minutes, then power back on).

2. Inconsistent Functionality

• Step 1: Use the diagnostic tool to read any fault codes. Note the codes and refer to the Tesla service manual for guidance.
• Step 2: If the fault codes indicate a specific sensor, replace that sensor. Remove the bumper cover if necessary to access the sensor.
• Step 3: Install the new sensor by reversing the removal process. Ensure to torque any bolts to the manufacturer's specifications.

3. Sensor Damage

• Step 1: Remove the damaged sensor using screwdrivers and trim removal tools.
• Step 2: Install the new sensor, ensuring all connectors are secure.
• Step 3: Reattach the bumper cover and torque to specifications.

4. Calibration Issues

• Step 1: If the sensors require recalibration, follow the Tesla service manual instructions for recalibrating the parking sensors. This may involve specific software steps.
• Step 2: After recalibration, perform a functionality test to ensure accuracy.
