Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery Condition:
- Clean terminals with a wire brush if corroded.
- Tighten any loose connections.
Test Battery:
- If the voltage is low, charge the battery using a battery charger.
- If it fails to hold a charge, replace the battery.
- Tools Required: Multimeter, battery charger.
- Parts Required: New battery (if needed).

3. Starter and Relay Replacement

Check and Replace Starter Relay:
- Locate the starter relay in the fuse box.
- Swap with a similar relay to test functionality.
- If faulty, replace with a new relay.
