Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Clean battery terminals using a battery terminal cleaner to remove corrosion.
2. Reconnect the battery terminals securely.
3. If the battery is found faulty, remove the battery using a socket set (usually 10mm).
4. Install a new battery, ensuring the positive terminal connects first followed by the negative.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor beneath the vehicle, typically near the engine.
2. Disconnect the wiring harness from the starter motor.
3. Remove the mounting bolts (usually 12mm) using a socket set.
4. Inspect the starter gear for wear; replace the starter motor if necessary.
5. Install the new starter motor and torque the bolts to the manufacturer specifications (typically around 15-20 ft-lbs).

4. Testing Relay and Fuse

Sub-steps:
1. Locate the fuse box and identify the starter relay and fuse.
2. Remove the starter relay and use a multimeter to test for continuity.
3. Replace the relay if it is faulty or replace the fuse if blown.
4. Reinstall the relay and fuse securely.
