Solution

1. Preparation

Gather necessary tools: multimeter, socket set, OBD-II scanner, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Step 1: Disconnect the negative battery terminal using a socket wrench.
Step 2: Clean the battery terminals and cable ends with a wire brush if corrosion is present.
Step 3: Reconnect the negative terminal and ensure it is tight.

3. Starter Relay Check

Step 1: Locate the starter relay in the fuse box (refer to the owner’s manual for exact location).
Step 2: Remove the relay and visually inspect it for signs of damage.
Step 3: Swap the starter relay with a similar relay (e.g., horn relay) to test functionality.

4. Starter Motor Replacement (if necessary)

Step 1: Disconnect the negative battery terminal again.
Step 2: Remove any covers or shields obstructing access to the starter motor.
Step 3: Disconnect the wiring harness from the starter motor.
Step 4: Remove the mounting bolts securing the starter motor using a socket set.
Step 5: Install the new starter motor by reversing the removal steps and torque the bolts to the manufacturer’s specifications (typically around 15-20 ft-lbs).
