2. Battery Inspection and Replacement

Sub-step 1: Reconnect the battery and test voltage again. If below 12.4 volts, charge or replace the battery.
Sub-step 2: If replacing, remove the positive terminal first, followed by the negative terminal.
Sub-step 3: Replace the battery, connecting the positive terminal first, then the negative terminal.
Tools Required: Socket set for battery terminals.

3. Starter Relay and Fuse Check

Sub-step 1: Remove the starter relay from the fuse box.
Sub-step 2: Replace the relay with a new one or a known-good relay of the same type.
Sub-step 3: Inspect and replace any blown fuses related to the starting system as identified in the diagnostic steps.
Tools Required: Fuse puller or flathead screwdriver.

4. Starter Motor Inspection

Sub-step 1: Locate the starter motor underneath the vehicle.
Sub-step 2: Disconnect the wiring harness and remove the mounting bolts using a socket set.
Sub-step 3: Inspect the starter for signs of wear or damage; replace if necessary.
Tools Required: Socket set, wrenches.

5. Final Checks
