Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Gather all necessary tools.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from the battery terminals and cable ends using a wire brush.
3. If the battery voltage is below 12.4 volts, charge or replace the battery.
4. Reinstall the battery (positive terminal first, then negative).
Tools Required: Multimeter, wire brush, socket set.
Safety Warnings: Wear gloves and safety goggles when handling the battery.

3. Ignition Switch Testing

Sub-steps:
1. Remove the ignition switch cover using a screwdriver.
2. Disconnect the wiring harness from the ignition switch.
3. Use a multimeter to check for continuity when the key is turned to the "start" position. If no continuity is detected, replace the ignition switch.
Tools Required: Screwdriver, multimeter.

4. Starter Motor and Relay Check

Sub-steps:
1. Locate the starter motor (generally near the engine block).
2. Test the starter motor by applying direct battery voltage to the motor terminals; if it does not engage, replace the starter.
3. Check the starter relay by swapping it with a similar relay in the fuse box (if available).
Tools Required: Socket set, jumper wires.
Safety Warnings: Ensure the vehicle is in a secure position to prevent rolling.
