Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, torque wrench.
Ensure the vehicle is in a safe location with the ignition off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-step 1: Remove the battery terminals (negative first) and inspect for corrosion. Clean terminals if needed.
Sub-step 2: If the battery voltage is below 12.4 volts, jump-start the vehicle or replace the battery if it fails to hold a charge.
Tools Required: Battery terminal cleaner, ratchet and socket for battery terminals.

3. Starter and Relay Check

Sub-step 1: Locate the starter relay in the fuse box and swap it with a similar relay.
Sub-step 2: If the vehicle starts, replace the faulty relay.
Sub-step 3: If the issue persists, remove the starter motor for testing.
Tools Required: Socket set, screwdriver.

4. Starter Motor Replacement

Sub-step 1: Disconnect the negative battery terminal again for safety.
Sub-step 2: Remove the wiring harness from the starter motor.
Sub-step 3: Unbolt the starter motor from its mount using a socket wrench.
Sub-step 4: Install the new starter motor, torque bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Tools Required: Socket set, torque wrench.
