Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual) and set the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Battery Connections

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean the terminals and cable ends with a wire brush or terminal cleaner.
3. Reconnect the terminals, securing them tightly (positive first, then negative).

3. Test and Replace the Battery (if necessary)

Sub-steps:
1. Reconnect the battery and test the voltage with a multimeter.
2. If the voltage is low (below 12.4 volts), charge the battery or replace it.
3. Install a new battery if needed, ensuring proper orientation and connection.

4. Inspect and Replace the Starter Relay

Sub-steps:
1. Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
2. Remove the relay and visually inspect it for damage.
3. Replace with a new or functioning relay if necessary.

5. Test Starter Motor

Sub-steps:
1. If the issue persists, access the starter motor (may involve removing other components).
2. Use a multimeter to test for power at the starter terminal when the key is turned to the start position.
3. If no power is present, check wiring and switches; replace the starter motor if needed.
