Solution

1. Preparation

Gather tools and parts before starting the repair.
Tools required: Multimeter, socket set, torque wrench, jumper wire, OBD-II scanner.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative battery terminal using a socket wrench.
2. Clean the terminals with a wire brush if corrosion is present.
3. Reconnect the battery terminals and ensure they are tight.

3. Starter Relay Check

Sub-steps:
1. Locate the starter relay in the fuse box (consult the owner’s manual for location).
2. Remove the starter relay and inspect for signs of burning or corrosion.
3. Replace the relay if damaged or swap it with a similar relay for testing.

4. Starter Motor Inspection

Sub-steps:
1. Disconnect the wiring harness from the starter motor.
2. Use a multimeter to check for voltage at the starter when the key is turned.
3. If voltage is present but the starter does not engage, remove the starter from the vehicle.
  - Tools required: Socket set (usually 10mm and 13mm sockets).
4. Test the starter on a bench or have it tested at an auto parts store.
5. Replace the starter if it fails the test.

5. Reassembly

Sub-steps:
1. Reinstall the starter motor and reconnect the wiring harness.
2. Reconnect the battery terminals.
3. Ensure all connections are tight and double-check the installation.
