Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is in a safe, flat area, and the ignition is turned off.
Disconnect the negative terminal of the battery to avoid electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal followed by the positive terminal.
2. Clean any corrosion from the terminals using a wire brush.
3. Test the battery with a multimeter again; if it reads below 12.4 volts, recharge or replace it.
4. If replacing, install a new battery, ensuring correct polarity.
5. Reconnect the battery terminals, starting with the positive terminal followed by the negative terminal.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor underneath the vehicle.
2. Disconnect the electrical connector from the starter.
3. Use a jumper wire to connect the positive battery terminal directly to the starter motor’s terminal (ensure the vehicle is in neutral).
4. If the starter engages and the engine cranks, the starter is faulty and needs replacement.

4. Inspecting and Replacing the Ignition Switch

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Disconnect the wiring harness from the ignition switch.
3. Use a multimeter to check for continuity in the ignition switch.
4. If faulty, replace the ignition switch with a new one and reassemble the steering column.
