Solution

1. Preparation

Gather tools and materials.
Disconnect the negative battery cable.
Tools Required: Socket set, multimeter, jumper cables, wrenches.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion with a wire brush.
- Tighten the connections securely.
Test Battery Voltage:
- Connect a multimeter to the battery terminals.
- If voltage is below 12.4 volts, proceed to replace the battery.
Replace Battery:
- Remove the battery hold-down clamps using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Install the new battery by connecting the positive terminal first, then the negative terminal, and secure it with the clamps.

3. Starter Motor Inspection

Check Starter Relay:
- Locate the starter relay in the fuse box (refer to the vehicle’s manual for exact location).
- Swap the relay with another of the same type.
Test Starter Motor:
- If the clicking persists, disconnect the starter motor wires.
- Use jumper cables to connect directly to the starter motor to check for operation.
- If the starter does not engage, replace the starter motor.
