Solution

1. Battery Inspection and Cleaning

Sub-steps:
1. Disconnect the negative terminal first, then the positive terminal from the battery.
2. Inspect the terminals for corrosion. Clean them using a mixture of baking soda and water, then rinse with water and dry completely.
3. Reconnect the positive terminal first, followed by the negative terminal.

2. Battery Replacement (if necessary)

Tools Required: Socket set, battery terminal cleaner
Sub-steps:
1. Remove the battery hold-down bracket using a socket wrench.
2. Carefully lift out the old battery and place it on a flat surface.
3. Install the new battery in the reverse order, ensuring the terminals are properly connected.
4. Secure the battery with the hold-down bracket.

3. Starter Motor Inspection

Tools Required: Multimeter, socket set
Sub-steps:
1. Locate the starter motor, typically found near the transmission.
2. Disconnect the wiring harness and the battery cable from the starter.
3. Use a multimeter to check for power at the starter terminal while someone turns the key to the start position.
4. If there is power but the starter does not engage, replace the starter motor.
