Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Replacement

Tools Required: Wrench set, battery terminal cleaner, multimeter
Sub-steps:
1. Remove the battery hold-down bracket using a wrench.
2. Disconnect the positive (+) terminal followed by the negative (-) terminal.
3. Carefully lift out the old battery and clean the battery tray.
4. Place the new battery into the tray, ensuring it is secure.
5. Connect the positive (+) terminal first, followed by the negative (-) terminal.
6. Reinstall the battery hold-down bracket.

3. Starter Motor Inspection/Replacement

Tools Required: Socket set, torque wrench, multimeter
Sub-steps:
1. Locate the starter motor, typically near the transmission.
2. Disconnect the battery (if not already done).
3. Remove the electrical connections from the starter motor.
4. Unbolt the starter motor using the socket set.
5. Replace with a new starter motor, ensuring it is properly aligned.
6. Reconnect the electrical terminals and torque the bolts to manufacturer specifications.

4. Ignition Switch and Relay Check

Tools Required: Multimeter, screwdrivers
Sub-steps:
