Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, and safety gloves.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery to prevent short circuits.
2. Clean any corrosion from battery terminals using a wire brush or terminal cleaner.
3. Reconnect the battery terminals securely, starting with the positive terminal first.

3. Starter Relay Replacement

Sub-steps:
1. Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
2. Remove the starter relay by pulling it straight out of the socket.
3. Replace with a new or swapped relay to test functionality.

4. Starter Motor Testing

Sub-steps:
1. Disconnect the battery again for safety.
2. Remove the starter motor from its mounting (typically involves unbolting and disconnecting electrical connectors).
3. Bench test the starter by connecting it directly to a charged battery to check for operation.
4. If the starter does not engage, replace it with a new unit.
