Solution

1. Preparation

Ensure the vehicle is in park or neutral and the parking brake is applied.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Tools Required: Multimeter, wire brush, wrench
Clean battery terminals using a wire brush to remove any corrosion.
Reconnect the battery and retest the voltage with the multimeter.
If the voltage is low (below 12.4 volts), replace the battery.

3. Starter Motor Testing

Tools Required: Jumper wire, socket set
Locate the starter motor, typically near the transmission.
Disconnect the wiring harness from the starter.
Use a jumper wire to connect the battery positive terminal directly to the starter terminal to see if it engages.
If the starter engages and the engine cranks, replace the starter motor.

4. Ignition Switch Checking

Tools Required: Screwdriver set, multimeter
Remove the steering column cover to access the ignition switch.
Test the ignition switch for continuity in various positions (OFF, ACC, ON, START).
If there is no continuity in the START position, replace the ignition switch.
