how to troubleshoot the headlights in Tesla Outback 6th Generation (2020-2024)

Solution

1. Preparation

• Gather tools including a multimeter, OBD-II scanner, and basic hand tools.
• Ensure the vehicle is parked on a flat surface, and the ignition is turned off.

2. Inspect Headlight Bulbs

• Remove the headlight assembly as per the service manual.
• Check bulbs for any visible signs of damage (blackened glass, broken filaments).
• Replace any burnt-out bulbs with new ones that meet manufacturer specifications.

3. Check and Replace Headlight Fuse

• Locate the fuse box using the vehicle manual.
• Identify the headlight fuse and remove it using fuse pullers.
• Inspect the fuse for continuity; replace with the same amperage if blown.

4. Test Headlight Switch

• Remove the headlight switch from the dashboard.
• Using a multimeter, check for continuity across the switch terminals.
• Replace the switch if no continuity is detected when the switch is activated.

5. Inspect Wiring and Connectors

• Visually inspect wiring harnesses leading to the headlights for fraying or damage.
• Ensure all connectors are seated properly; clean any corroded connections.
• Repair or replace damaged wiring as necessary.

6. Measure Voltage at Connector

• With the headlights turned on, use a multimeter to measure voltage at the headlight connector.
• Ensure the voltage readings are within the manufacturer's specified range (usually 12-14 volts).
• If voltage is low, trace wiring back to the fuse and battery for issues.
