Solution

1. Preparation

Gather tools and materials. Ensure the vehicle is in park (or neutral) and the ignition is off.
Tools Required:
- Multimeter
- Socket set
- Screwdriver set
- Battery terminal cleaner
- Load tester

2. Battery Inspection and Replacement

Check Battery Condition
- Disconnect the negative terminal first, then the positive terminal.
- Clean the battery terminals using a terminal cleaner.
- Reconnect the terminals, ensuring a tight fit.
Replace Battery if Necessary
- If the battery voltage is below 12.4 volts or fails the load test, remove the old battery.
- Install a new battery, ensuring it matches the specifications (group size, cold cranking amps).
- Connect the positive terminal first, followed by the negative terminal.

3. Starter Inspection

Access Starter Motor
- Locate the starter motor beneath the vehicle. You may need to remove any undercarriage covers.
- Safety Warning: Disconnect the battery before working on electrical components.
Test and Replace Starter Motor
- If the starter relay is functioning and the battery is good, check the starter motor.
- Remove the wiring harness and the mounting bolts securing the starter motor.
- Replace with a new starter motor if it does not engage when tested directly from the battery.
