Solution

1. Preparation

Tools Required: Multimeter, Wrench set, Jumper wire, Torque wrench
Ensure the vehicle is in "Park" (automatic) or "Neutral" (manual).
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Service

Sub-steps:
1. Clean the battery terminals using a wire brush to remove any corrosion.
2. Tighten the battery cables to ensure a secure connection.
3. If the battery voltage is low (below 12.4 volts), attempt to jump-start the vehicle or replace the battery.

3. Starter Inspection

Sub-steps:
1. Remove the starter motor by disconnecting the electrical connections and unscrewing mounting bolts.
2. Inspect the starter for damage or wear, including the solenoid.
3. If the starter is faulty, replace it with a new unit, ensuring proper alignment during installation.
4. Reconnect the electrical connections and torque bolts to the manufacturer's specifications.

4. Ignition Switch Check

Sub-steps:
1. Locate the ignition switch, typically found on the steering column.
2. Disconnect the wiring harness and inspect for damage.
3. Use a multimeter to check for continuity when the key is turned to the "Start" position.
4. If there is no continuity, replace the ignition switch.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle to test if the issue is resolved.
