Solution

1. Preparation

Ensure the vehicle is in park and the ignition is off.
Gather tools: multimeter, socket set, and jumper cables.
Wear safety glasses and gloves for protection.

2. Battery Inspection

Sub-steps:
1. Use a multimeter to measure the voltage across the battery terminals. A healthy battery should read between 12.4 to 12.7 volts.
2. If the battery voltage is below 12.4 volts, proceed to jump-start the vehicle.
3. If jump-starting is successful, replace the battery if it fails to hold a charge.
Tools Required: Multimeter, jumper cables.

3. Battery Terminal Checks

Sub-steps:
1. Disconnect the negative battery terminal first, then the positive.
2. Inspect for corrosion; clean terminals with a wire brush if necessary.
3. Tighten the connections securely and reconnect in reverse order (positive first, then negative).
Tools Required: Wire brush, socket set.

4. Starter Relay and Fuse Inspection

Sub-steps:
1. Locate the starter relay in the fuse box (consult the owner's manual for exact location).
2. Swap the starter relay with a similar relay in the fuse box to check for functionality.
3. Inspect fuses related to the ignition and start system; replace any blown fuses.
Tools Required: Fuse puller, socket set.

5. Starter System Test

Sub-steps:
1. If the above steps do not resolve the issue, check the starter motor by testing for power at the starter terminal when the key is turned.
2. If power is present and the starter does not engage, replace the starter motor.
Tools Required: Multimeter, socket set.
