Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a flat surface, turn off the ignition, and set the parking brake.

2. Battery Inspection and Replacement

Disconnect Battery:
- Use a socket set to remove the negative terminal first, followed by the positive terminal.
- Safety Warning: Ensure the ignition is off and all electrical accessories are turned off.
Inspect and Clean Terminals:
- Check for corrosion on battery terminals.
- Clean terminals with a mixture of baking soda and water if corrosion is present.
Test Battery:
- Reconnect the multimeter to the battery; if the voltage is low, replace the battery.
- If necessary, remove the old battery and install a new one, securing it in place.

3. Starter Motor Inspection and Replacement

Access Starter Motor:
- Raise the vehicle using a jack and secure it with jack stands.
- Remove any components obstructing access to the starter motor, such as the engine cover or splash shield if applicable.
Test Starter Motor Operation:
- Use a multimeter to check for voltage at the starter terminal when the ignition is turned to the start position.
- If there is no voltage, the ignition switch may need testing or replacement.
Remove Starter Motor:
- Disconnect wiring harness and remove mounting bolts using a socket set.
- Carefully remove the starter motor from its position.
Install New Starter Motor:
- Position the new starter motor and secure it with the mounting bolts.
