Solution

1. Preparation

• Tools Required: Socket set, torque wrench, OBD-II scanner, fluid catch pan
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Drain and Replace Transfer Case Fluid

• Sub-steps:
  1. Place a fluid catch pan under the transfer case.

  4. Remove the fill plug and refill the transfer case with the recommended fluid type (typically Honda Dual Pump Fluid or equivalent).
  5. Replace the fill plug and tighten to the specified torque.

3. Inspect and Replace Transfer Case Actuator (if necessary)

• Sub-steps:
  1. Locate the transfer case actuator, usually mounted on the side of the transfer case.
  2. Disconnect the electrical connector from the actuator.
  3. Remove the mounting bolts securing the actuator and take it off the transfer case.
  4. Install the new actuator by reversing the removal steps, ensuring all connections are secure.

4. Reconnect Battery and Test

• Sub-steps:
  1. Reconnect the negative battery terminal securely.
  2. Start the engine and allow it to idle.
