Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner, safety gloves.
Safety Warnings: Disconnect the battery before working on electrical systems to prevent short circuits.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Remove the negative (-) terminal first, then the positive (+) terminal.
- Clean any corrosion with a terminal cleaner and reattach securely.
Test Battery Voltage:
- Use a multimeter to check voltage; if below 12.4 volts, recharge or replace the battery.
Replace Battery (if required):
- Remove the battery hold-down bracket using the socket set.
- Lift out the old battery and replace with a new one, ensuring correct polarity.
- Reattach the positive (+) terminal first, followed by the negative (-) terminal.

3. Starter and Relay Inspection

Check Starter Relay:
- Locate the starter relay in the fuse box (refer to the owner’s manual).
- Remove and test with a multimeter; replace if faulty.
Inspect Starter Motor:
- Use the socket set to remove the starter motor from its mounting.
- Test for continuity with a multimeter; replace the starter if defective.

4. Reassembly and Final Checks

Reassemble Components:
- Reattach any removed components, ensuring all bolts are torqued to specifications.
