Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is in a safe location with the engine off.
• Disconnect the negative battery terminal to avoid electrical shorts.

2. Battery Inspection

• Sub-steps:
  1. Clean battery terminals with a wire brush to remove corrosion.
  2. Reconnect the battery and retest the voltage; ensure it is above 12.4 volts.
  3. If the battery is weak, jump-start the vehicle or replace the battery as necessary.

3. Starter Relay Replacement

• Sub-steps:
  1. Locate the fuse box; consult the owner’s manual for the exact location of the starter relay.

  3. If no voltage is present, replace the ignition switch.

5. Starter Motor Inspection

• Sub-steps:
  1. Locate the starter motor; typically found near the transmission.
