Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe working environment, parked on a flat surface with the engine off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from terminals using a wire brush.
- If battery voltage is below 12.4 volts, charge or replace the battery.
Replace Battery (if needed):
- Remove the old battery and install the new battery in reverse order.
- Secure battery terminals tightly (positive first, then negative).

3. Starter Motor Check and Replacement

Check Starter Motor:
- Locate the starter motor under the vehicle.
- Inspect for loose connections and secure them.
Replace Starter Motor (if necessary):
- Disconnect the wiring harness from the starter.
- Remove the starter motor mounting bolts using a socket set.
- Install the new starter motor and tighten the bolts to the manufacturer's specifications (typically around 15-30 Nm).
- Reconnect the wiring harness.

4. Reassembly and Final Checks

Reconnect the negative battery terminal.
Start the vehicle to ensure the issue is resolved.
