Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is in a safe location with the engine off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

• Sub-steps:
  1. Inspect battery terminals for corrosion; clean if necessary.
  2. Use a multimeter to check battery voltage.
  3. If the battery voltage is low, or the battery is old, replace the battery.
  4. Remove the battery using a socket set (usually 10mm) to loosen the hold-down clamp.
  5. Install the new battery, ensuring the positive terminal is connected first, followed by the negative.

3. Starter Motor Testing and Replacement

• Sub-steps:
  1. Locate the starter motor; it is typically mounted on the engine block.
  2. Disconnect the electrical connectors and remove the mounting bolts using a socket set.
  3. Inspect the starter motor for damage or wear.
  4. If the motor is faulty, replace it with a new one, ensuring proper alignment during installation.
  5. Reconnect the electrical connectors and secure the starter motor with bolts, torqueing them to manufacturer specifications.

4. Relay and Electrical Check

• Sub-steps:
  1. Locate the starter relay in the fuse box.
  2. Remove and test the relay with a multimeter for continuity.
  3. Replace the relay if it is defective.
  4. Inspect any fuses related to the starting system; replace any that are blown.
