Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

Tools Required:

Multimeter
Socket set
Screwdriver set
OBD-II scanner (if needed for error codes)

2. Inspect and Replace Fog Light Bulbs

Access the fog light assembly by removing the necessary undercarriage cover (if applicable).
Twist and remove the fog light bulb from the socket.
Inspect the bulb for any signs of damage or filament breakage.
If damaged, replace with a new bulb of the same specification (typically H11 for CR-V).
Reinsert the new bulb into the socket and secure it in place.

3. Check and Replace the Fog Light Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the fog light fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity with a multimeter.
If the fuse is blown, replace it with a fuse of the same amperage (usually 10A).
Reinstall the fuse and close the fuse box.

4. Test the Fog Light Switch

Reconnect the battery.
Turn on the ignition without starting the vehicle.
Use a multimeter to check for power at the fog light switch.
If the switch is not receiving power, trace the wiring back to identify any breaks or issues.

5. Inspect and Replace the Relay

Locate the fog light relay in the fuse box.
Remove the relay and check for continuity.
If the relay is faulty, replace it with a new one.
Reinstall the relay in its original position.
