Solution

1. Preparation

Tools Required:
- Multimeter
- Battery tester
- Socket set
- Torque wrench
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect the negative terminal of the battery to prevent electrical shorts.
Clean the battery terminals using a wire brush if corrosion is present.
Reconnect the battery terminals securely.
If the battery is weak or faulty, remove it using a socket set and replace it with a new one.
Torque the battery hold-down clamps to the manufacturer’s specifications.

3. Starter Motor Inspection and Replacement

Disconnect the negative battery terminal again for safety.
Locate the starter motor, usually near the transmission.
Inspect the wiring and connections; tighten any loose connections.
If the starter motor is defective, remove it using a socket set.
Install a new starter motor and torque the mounting bolts to specifications.
Reconnect the battery terminals.

4. Relay Check and Replacement

Locate the starter relay in the fuse box.
Remove the relay and visually inspect it for any damage.
If faulty, replace it with a new relay of the same type.
Ensure all connections are secure.
