Solution

1. Preparation

Gather tools including a multimeter, wrench set, and screwdriver.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection

Step 1: Disconnect the negative battery cable (use a wrench).
Step 2: Clean the battery terminals with a wire brush to remove any corrosion.
Step 3: Reconnect the battery terminals securely.

3. Starter Relay Replacement

Step 1: Locate the starter relay in the fuse box (consult the owner's manual for the exact location).
Step 2: Remove the relay by pulling it straight out.
Step 3: Insert a new starter relay (ensure it matches the original specifications).

4. Ignition Switch Inspection

Step 1: Remove the steering column cover (usually requires a screwdriver).
Step 2: Inspect the ignition switch wiring for damage or loose connections.
Step 3: If necessary, remove the ignition switch and replace it with a new one.

5. Starter Motor Testing

Step 1: If the clicking persists, access the starter motor (usually located near the transmission).
Step 2: Check the wiring connections to the starter motor for tightness and corrosion.
Step 3: Perform a direct connection test to the starter motor using jumper cables to see if it engages.
