Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is in park or neutral.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Sub-steps:
- Remove the battery terminals (negative first, then positive).
- Inspect the terminals for corrosion; clean with a wire brush if necessary.
- Reconnect the terminals securely.
Tools Required: Wire brush, terminal cleaning tool.

3. Battery Replacement (if necessary)

Sub-steps:
- If the battery voltage is below 12.4 volts, replace the battery.
- Remove the old battery by unscrewing the hold-down clamp and lifting it out.
- Install the new battery, ensuring correct polarity (positive to positive, negative to negative).
- Reconnect the terminals (positive first, then negative).
Tools Required: Socket set for battery clamp.

4. Starter Inspection

Sub-steps:
- If the battery is good, locate the starter motor.
- Check connections at the starter for tightness and signs of wear.
- If necessary, remove the starter motor for bench testing.
Tools Required: Socket set, torque wrench.

5. Replace Starter (if necessary)

Sub-steps:
- If the starter is faulty, install a new starter by reversing the removal process.
- Torque the mounting bolts to the manufacturer’s specifications.
- Reconnect electrical connections to the starter.
Tools Required: Torque wrench.
