Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Sub-steps:
1. Reconnect the battery terminal and check voltage again.
2. If the battery voltage is below 12.4 volts, charge or replace the battery.
3. Clean the terminals with a wire brush if corrosion is present.
Tools Required: Multimeter, wire brush.

3. Starter Relay and Fuse Check

Sub-steps:
1. Locate the fuse box and identify the starter relay and fuse positions.
2. Remove the starter relay and test for continuity with a multimeter.
3. Replace any blown fuses and the relay if faulty.
Tools Required: Multimeter, fuse puller.

4. Starter Motor Test

Sub-steps:
1. Locate the starter motor.
2. Using a jumper wire, connect the battery directly to the starter terminal.
3. If the motor engages, the starter is functional; if not, replace the starter motor.
Tools Required: Jumper wire, socket set.

5. Reassemble

Sub-steps:
1. Reconnect any removed components.
2. Reconnect the negative battery terminal.
3. Start the vehicle to confirm repair success.
