Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, jumper cables, socket set, safety gloves, and safety glasses.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery.
2. Clean the battery terminals and cable connections using a wire brush.
3. Reconnect the battery terminals tightly, ensuring a good connection.
4. If the battery voltage is low (below 12.6 volts), recharge or replace the battery.

3. Starter Motor Check

Sub-steps:
1. Locate the starter motor (usually near the transmission).
2. Disconnect the wiring harness from the starter.
3. Use a multimeter to check for voltage at the starter terminal when the key is turned to the start position.
4. If there is no voltage, the ignition switch or relay may be faulty.
5. If voltage is present, bench-test the starter by connecting it directly to the battery.

4. Ignition Switch and Relay Inspection

Sub-steps:
1. Locate the ignition switch and ensure all connectors are secure.
2. Check the starter relay (usually located in the fuse box) by swapping it with a similar relay.
3. If the relay is defective, replace it with a new one.
