Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, and a wrench.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Battery Inspection

Sub-step 1: Visually inspect the battery for any physical damage or leaks.
Sub-step 2: Clean the battery terminals with a wire brush to remove any corrosion.
Sub-step 3: Reconnect the battery terminals securely.

3. Starter Relay Check

Sub-step 1: Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
Sub-step 2: Remove the starter relay and visually inspect for damage.
Sub-step 3: Swap the relay with another of the same type to test functionality.

4. Starter Motor Testing

Sub-step 1: Locate the starter motor, often found near the transmission bell housing.
Sub-step 2: Use a jumper wire to connect the positive terminal of the starter to the battery; if it engages, the starter is functioning.
Sub-step 3: If the starter does not engage, it may need replacement.

5. Replacement of Components

If the battery is weak, replace it with one that meets OEM specifications (typically 12V, Group 48).
If the starter is faulty, remove it using a socket set (typically requires 10mm and 13mm sockets) and install a new starter motor.
