Solution

1. Preparation

Gather tools: Multimeter, socket set, screwdriver, and battery terminal cleaner.
Ensure the vehicle is in a safe position (parked on level ground) and the keys are removed from the ignition.

2. Battery Inspection and Cleaning

Sub-step 1: Disconnect the negative battery terminal first to prevent any short circuits.
Sub-step 2: Remove the positive battery terminal.
Sub-step 3: Clean the battery terminals with a battery terminal cleaner or a mixture of baking soda and water to remove corrosion. Rinse and dry.
Sub-step 4: Reconnect the positive terminal first, followed by the negative terminal.

3. Battery Replacement (if necessary)

Sub-step 1: If the battery is found to be faulty during testing, remove the old battery by loosening the terminal bolts and lifting it out carefully.
Sub-step 2: Install the new battery in the reverse order, ensuring tight connections on both terminals.
Sub-step 3: Secure the battery hold-down bracket.

4. Starter and Relay Check

Sub-step 1: If the battery does not resolve the issue, locate the starter relay and test it by swapping with another relay of the same type.
Sub-step 2: If necessary, remove the starter motor by disconnecting wires and unscrewing it from its mounting.
Sub-step 3: Test the starter motor with direct battery voltage to confirm functionality.
