Solution

1. Preparation

Gather tools: multimeter, socket set, torque wrench, battery terminal cleaner, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative (-) battery terminal using a socket wrench.
2. Clean the battery terminals with a terminal cleaner to remove any corrosion.
3. Reconnect the terminals and ensure they are tightly secured.

3. Battery Replacement (if necessary)

Sub-steps:
1. If the battery voltage is low or the load test fails, remove the battery by disconnecting the positive (+) terminal first, followed by the negative (-) terminal.
2. Remove the battery hold-down bracket and carefully lift the battery out of the tray.
3. Install the new battery in reverse order: place it in the tray, secure the hold-down bracket, and connect the positive terminal first, then the negative terminal.

4. Starter Inspection/Replacement

Sub-steps:
1. If the battery is good, locate the starter motor, typically mounted on the engine block.
2. Disconnect the wiring harness from the starter motor.
3. Remove the bolts securing the starter motor using a socket set.
4. Remove the starter motor from the vehicle.
5. Install the new starter motor by reversing the removal steps, ensuring all connections are secure.
