Solution

1. Preparation

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

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery.
Sub-step 2: Clean the battery terminals and cable ends using a wire brush.
Sub-step 3: Reconnect the terminals securely, starting with the positive terminal followed by the negative.

3. Starter Motor Replacement (if necessary)

Sub-step 1: Disconnect the battery (negative terminal) again for safety.
Sub-step 2: Remove any components obstructing access to the starter motor (e.g., air intake duct).
Sub-step 3: Unbolt and disconnect the electrical connections on the starter motor.
Sub-step 4: Remove the starter motor from its mounting position.
Sub-step 5: Install the new starter motor in reverse order, ensuring all bolts are torqued to manufacturer specifications (typically around 15-25 lb-ft).

4. Final Checks

Sub-step 1: Reconnect the battery and ensure all connections are tight.
Sub-step 2: Verify that all components removed are reinstalled correctly.
Sub-step 3: Attempt to start the vehicle to confirm the issue is resolved.
