Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during the repair.

2. Fluid Change

Drain Transfer Case Fluid:
- Locate the drain plug on the transfer case.
- Using a socket set, remove the drain plug and allow the fluid to drain completely into a container.
Inspect Fluid:
- Check the condition of the drained fluid for metal shavings or burnt smell, indicating internal damage.
Replace with New Fluid:
- Reinstall the drain plug with the appropriate torque (refer to the service manual for specific torque values).
- Use a funnel to fill the transfer case with new fluid, ensuring it meets Honda specifications.

3. Wheel Speed Sensor Check

Remove Wheel Assemblies:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheels to gain access to the wheel speed sensors.
Inspect Sensors:
- Check for dirt, corrosion, or damage on the sensors and connectors.
- Clean the sensors and connectors using electrical cleaner if necessary.
Test Sensor Output:
- Using a multimeter, test the sensor output while spinning the wheel to ensure proper voltage readings.

4. Fuse Replacement (if necessary)

Locate Fuse Box:
- Find the fuse box location (refer to the owner's manual).
Inspect and Replace Fuses:
- Identify the AWD-related fuses, check for blown fuses, and replace them with fuses of the same rating.
