Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Sub-step 1: Reconnect the battery and use a multimeter to measure the voltage.
Sub-step 2: If the voltage is below 12.4 volts, charge or replace the battery.
Sub-step 3: Clean the battery terminals and cable connections with a wire brush and apply dielectric grease.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor under the vehicle.
Sub-step 2: Disconnect electrical connections from the starter.
Sub-step 3: Use jumper cables to connect the starter directly to the battery (positive to the starter terminal, negative to the starter housing).
Sub-step 4: If the starter engages and the motor cranks, replace the starter.

4. Ignition Switch Check

Sub-step 1: Locate the ignition switch and remove it from the steering column.
Sub-step 2: Use a multimeter to check for continuity when the ignition key is turned to the start position.
Sub-step 3: If there is no continuity, replace the ignition switch.

5. Reassembly

Sub-step 1: Reconnect all components, ensuring they are secure and properly fastened.
Sub-step 2: Reconnect the negative battery terminal.
Sub-step 3: Start the vehicle to confirm that the problem is resolved.
