Solution

1. Preparation

Gather tools: socket set, multimeter, jumper wire, and OBD-II scanner.
Ensure the vehicle is in the park position and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative battery terminal to prevent short circuits.
2. Clean any corrosion from the battery terminals using a wire brush.
3. Reconnect the battery terminals securely.
4. Measure the battery voltage; if below 12.4 volts, charge or replace the battery.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor (typically near the engine’s transmission).
2. Using a jumper wire, connect the positive terminal of the battery to the starter solenoid terminal.
3. If the starter engages and the engine turns over, the starter motor is functional.
4. If not, replace the starter motor.

4. Ignition Switch and Relay Check

Sub-steps:
1. Locate the ignition switch and relay under the dash.
2. Inspect the ignition switch connections for damage or wear.
3. Replace the ignition switch if necessary.
4. Test the starter relay by swapping it with a similar relay in the fuse box.
