Solution

1. Preparation

• Ensure the vehicle is in park or neutral and the ignition is off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

• Sub-steps:
  1. Reconnect the battery and use a multimeter to check the voltage; if below 12.4 volts, charge or replace the battery.
  2. If battery is good, clean the battery terminals using a wire brush and a battery terminal cleaner.
• Tools Required: Multimeter, wire brush, battery terminal cleaner.

3. Ignition Switch Testing and Replacement

• Sub-steps:
  1. Remove the steering column cover to access the ignition switch.
  2. Disconnect the ignition switch connector and test for continuity with a multimeter while turning the key to the start position.
  3. If no continuity is found, replace the ignition switch.
• Tools Required: Torx screwdriver set, multimeter.

4. Starter Relay and Wiring Inspection

• Sub-steps:
  1. Locate the fuse box under the hood and identify the starter relay.
  2. Swap the starter relay with a similar relay in the fuse box to test functionality.
  3. If the relay is functional, inspect the wiring leading from the relay to the starter for any breaks or damage.
• Tools Required: Fuse puller or needle-nose pliers.

5. Starter and Solenoid Replacement

• Sub-steps:
  1. Disconnect the negative battery terminal again to ensure safety.
  2. Remove the starter motor by unbolting it from the engine and disconnecting the wiring harness.
  3. If the solenoid is integrated with the starter, replace the entire unit; otherwise, replace the solenoid separately.
  4. Reinstall the starter, reconnect the wiring, and secure it with bolts.
• Tools Required: Socket set, torque wrench.
