Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, screwdriver set.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from the terminals and cable ends using a wire brush.
3. Reconnect the terminals (positive first, then negative).
4. Test battery voltage again to confirm it is sufficient.

3. Starter Relay Check

Sub-steps:
1. Locate the fuse box under the hood.
2. Identify the starter relay and remove it.
3. Swap it with a similar relay (e.g., horn relay) to test functionality.
4. If the starter works with the swapped relay, replace the faulty relay.

4. Starter Motor Replacement (if necessary)

Sub-steps:
1. Remove any components obstructing access to the starter motor.
2. Disconnect the starter wiring harness and solenoid connection.
3. Unbolt the starter motor from its mounting using a socket set.
4. Install the new starter motor, ensuring it is securely bolted.
5. Reconnect the wiring harness and solenoid connection.

5. Ignition Switch Testing

Sub-steps:
1. Access the ignition switch by removing the steering column cover.
2. Use a multimeter to test for voltage at the ignition switch output during the crank position.
3. If no voltage is detected, the ignition switch may need replacement.
