why does my Honda Civic 9th Generation (2012-2015) make a clicking sound when I turn the engine off

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, flashlight.
• Disconnect the battery before starting any work to ensure safety.

2. Inspect and Clean Battery Connections

• Sub-steps:
  1. Remove the negative (-) battery terminal first, then the positive (+) terminal.
  2. Clean the terminals and cable connections using a wire brush to remove any corrosion.
  3. Reconnect the positive (+) terminal first, then the negative (-) terminal, ensuring secure connections.

3. Check and Replace Faulty Relays

• Sub-steps:
  1. Locate the fuse box and identify the relays associated with the clicking noise.
  2. Remove the relays one at a time and inspect for signs of wear or damage.
  3. Replace any faulty relays with new ones of the same specifications.

4. Examine Starter Motor

• Sub-steps:
  1. Locate the starter motor, typically mounted near the transmission.
  2. Visually inspect for any signs of wear or damage.
  3. Use a multimeter to test for voltage at the starter when the engine is off to ensure it is not receiving power inadvertently.
  4. If the starter is faulty, remove it and replace it with a new starter motor.
