Solution

1. Preparation

Gather tools: multimeter, socket set, torque wrench, screwdriver, replacement battery (if needed).
Ensure the vehicle is in park (or neutral) and the parking brake is applied.
Disconnect the negative terminal of the battery to ensure safety.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from the terminals using a wire brush.
- Tighten the terminal connections to ensure a secure fit.
Test Battery Voltage
- Reconnect the battery, then use a multimeter to measure the voltage.
- If the reading is below 12.4 volts, replace the battery.
Replace Battery
- Disconnect the negative terminal first, followed by the positive terminal.
- Remove the battery hold-down and lift the old battery out.
- Place the new battery in the tray and secure it with the hold-down.
- Connect the positive terminal first, then the negative terminal.

3. Starter and Ignition System Repair

Check Ignition Switch
- Remove the steering column cover to access the ignition switch.
- Test the switch with a multimeter to ensure proper operation; replace if faulty.
Inspect Starter Relay
- Locate the relay in the fuse box; swap it with a similar relay to test.
- If the starter engages, replace the faulty relay.
Inspect Starter Motor
- If the starter still does not engage, check the starter motor connections.
- If damaged, remove the starter from the engine and replace it.
