Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Bulb

Remove the lens cover by unscrewing or unclipping it.
Take out the turn signal bulb from its socket.
Inspect the bulb for any breaks in the filament; replace if necessary.
Reinstall the new bulb and the lens cover.

Locate the fuse box (check the owner’s manual for the exact location).
Identify the fuse associated with the turn signals (typically labeled).
Use the fuse puller tool to remove the fuse.
Check the metal strip inside the fuse; replace with a new fuse of the same amperage if blown.

4. Test and Replace Relay

Locate the turn signal relay in the fuse box or under the dashboard (refer to the owner’s manual).
Remove the relay and test it with a multimeter to ensure continuity.
Replace with a new relay if it does not pass the continuity test.

5. Replace Turn Signal Switch (if necessary)
