Solution

1. Preparation

Gather all tools and parts required.
Ensure the vehicle is in a safe location with the ignition off.
Disconnect the negative battery terminal to prevent electrical short circuits.

2. Check and Replace Battery

Tools Required: Wrench set, battery terminal cleaner.
Inspect battery terminals and clean any corrosion using a battery terminal cleaner.
If the battery voltage is below 12.4 volts, replace the battery.
- Remove the battery hold-down bracket using the wrench.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and install the new one by connecting the positive terminal first, followed by the negative terminal.
- Secure the battery in place with the hold-down bracket.

3. Test and Replace Starter Motor

Tools Required: Socket set, torque wrench.
If the battery is functioning correctly, locate the starter motor.
Remove the wiring harness connected to the starter motor.
Unbolt the starter motor using a socket set and remove it from the engine.
Test the starter motor by connecting it directly to the battery.
- If it does not engage, replace the starter motor with a new one.
Install the new starter motor and torque the bolts to the manufacturer's specifications.

4. Check and Replace Starter Relay
