Test Battery Voltage:
- Reconnect the battery and use a multimeter to check the voltage.
- If the voltage is low (below 12.4 volts), proceed to replace the battery.
Replace Battery (if necessary):
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and install the new one in reverse order.
- Reconnect the negative terminal first, then the positive terminal.

3. Starter Motor Inspection

Locate the Starter Motor:
- Refer to the vehicle’s service manual for the exact location.
Test the Starter Motor:
- Disconnect the wiring harness from the starter.
- Use a multimeter to check for voltage at the starter terminal when the key is turned to the start position.
- If voltage is present and the starter does not engage, replace the starter motor.

4. Final Steps

Reconnect Battery:
- Reconnect the negative battery terminal securely.
Test Start the Vehicle:
